wrist, also called carpus, complex joint between the five metacarpal bones of the hand and the radius and ulna bones of the forearm. The wrist is composed of eight or nine small, short bones (carpal bones) roughly arranged in two rows.

What classification is the wrist joint?

condyloid synovial jointThe wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.

What is the movement of the wrist called?

Radial deviation, otherwise known as radial flexion, is the movement of bending the wrist to the thumb, or radial bone, side.

What muscles stabilize the wrist?

The extensor carpi radialis longus arises just above the ECRB muscle on the outside of the elbow and attaches to the 2nd hand bone. Along with the ECRB, its primary function is to straighten and stabilize the wrist. It also pulls the wrist into radial deviation.

How do I get bigger wrists?

To get bigger wrists, you can do curls and extensions, knuckle pushups, any exercise asking to squeeze your wrist hard (pull ups, chin ups and, deadlifts) or using hand grips. Don't overtrain, as it will impair your everyday life and set you back weeks in your progress.

What bones make up wrist joint?

Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.

What is wrist flexion?

Wrist flexion is the action of bending your hand down at the wrist, so that your palm faces in toward your arm. It's part of the normal range of motion of your wrist.

What is the hand called in anatomy?

The front, or palm-side, of the hand is referred to as the palmar side. The back of the hand is called the dorsal side. There are 27 bones within the wrist and hand.

Is scaphoid hand or wrist?

The scaphoid bone is one of the carpal bones on the thumb side of the wrist, just above the radius. The bone is important for both motion and stability in the wrist joint. The word "scaphoid" comes from the Greek term for "boat." The scaphoid bone resembles a boat with its relatively long, curved shape.

What is the anatomy of the hand?

The human hand is made up of the wrist, palm, and fingers and consists of 27 bones, 27 joints, 34 muscles, over 100 ligaments and tendons, and many blood vessels and nerves. The hands enable us to perform many of our daily activities such as driving, writing and cooking.

What are the bones of the wrist?

Bones of the wrist. The radius and ulna are the long bones of the forearm. The ulna is the larger of the two bones, although it tapers at the wrist end, to become narrower than the Radius. The Radius is positioned on the thumb side of the wrist, and the ulna on the little finger side.

Where are the muscles that act on the wrist located?

Most of the muscles which act on the wrist joint are situated within the forearm, with only the tendon crossing the joint and inserting on the hand. The muscles on the back of the forearm (dorsal aspect) act to extend the wrist or pull it back as if pulling a ring-pull:

Which nerve supplies the small finger and the outer half of the ring finger?

The ulnar nerve supplies the small finger and the outer half of the ring finger.

Which nerve is responsible for the development of carpal tunnel syndrome?

The median nerve is responsible for the development of carpal tunnel syndrome. It passes through the carpal tunnel and splits into four branches which each travel to the thumb and next three fingers. It provides sensation to all of these fingers, although only the inside half of the ring finger.

How many nerves pass through the wrist?

Three nerves pass from the forearm, across the wrist, and into the hand. These are:

What are the ligaments in the wrist?

As you can imagine, this results in a large number of ligaments! Two of the largest ligaments of the wrist are the medial (ulnar) and lateral (radial) collateral ligaments.

Which carpal bone crosses both rows?

Triquetrum – proximal. Pisiform – proximal. Capitate – distal. Trapezium – distal. Trapezoid – distal. Hamate – distal. Scaphoid. The scaphoid bone crosses both rows as it is the largest carpal bone. The scaphoid and the lunate are the two bones that actually articulate with the radius and ulna to form the wrist joint.

What bones are in the wrist?

Wrist. The wrist connects the hand to the forearm. It consists of the distal ends of the radius and ulna bones, eight carpal bones, and the proximal ends of five metacarpal bones. This arrangement of bones allows for a wide range of movement. The wrist can bend, straighten, move laterally, and rotate. It is relatively prone to injury.

What causes a wrist to become inflamed?

Repetitive stress is another condition that affects the wrist. It can be caused by typing, sports, or other activities that involve repetitive motions. Repetitive stress can cause the carpal tunnel to become thickened and inflamed. The carpal tunnel is a tube of nerves and tendons that passes through the wrist.

What causes swelling in wrist?

The wrist can also be affected by arthritis, including osteoarthritis, rheumatoid arthritis, and gout. These conditions involve swelling of the joints from various causes. Arthritis can worsen with age. Last medically reviewed on January 22, 2018.

What is the carpal tunnel?

The carpal tunnel is a tube of nerves and tendons that passes through the wrist. Tendinitis, sprains, and strain are other common injuries, which affect the connective tissues of the wrist. Wrist pain may also result from medical conditions, such as osteoporosis.

Can wrist bones be injured?

This arrangement of bones allows for a wide range of movement. The wrist can bend, straighten, move laterally, and rotate. It is relatively prone to injury. Force or stress can injure any of the bones. Fracture is one common injury. It involves swelling and pain.

What is the wrist made of?

Wrist injuries. Share on Pinterest. Your wrist is made up of many smaller bones and joints that allow your hand to move in several directions. It also includes the end of the arm bones. Let’s take a closer look.

How many joints does the wrist have?

The wrist has three main joints. This makes the wrist more stable than if it had only one joint. It also gives your wrist and hand a wide range of movement. The wrist joints let your wrist move your hand up and down, like when you lift your hand to wave.

What is the most common fracture in the wrist?

The most common kind of fracture in the wrist is a distal radius fracture. A scaphoid fracture is the most commonly broken carpal bone. This is the large bone on the thumb side of your wrist. It can fracture when you try to catch yourself in a fall or collision with an outstretched hand.

What is the condition where the ulna is slightly longer than the radius?

Impaction syndrome. Also called ulnocarpal abutment, this wrist condition happens when the ulna arm bone is slightly longer than the radius. This makes the ulnocarpal joint between this bone and your wrist bones less stable. Impaction syndrome can lead to increased contact between the ulna and carpal bones, leading to pain and weakness.

How do you sprain your wrist?

You can sprain your wrist by stretching it too far or carrying something heavy. A sprain happens when there’s damage to a ligament.

What connective tissue attaches muscles to bones?

Tendons. Tendons are another kind of elastic connective tissue that attaches muscles to bones. This lets you move your wrist and other bones.

What connects the wrist bones to each other?

Ligaments . Ligaments connect the wrist bones to each other and to the hand and forearm bones. Ligaments are like elastic bands that keep bones in place. They cross the wrist from each side to hold the bones together. Tendons. Tendons are another kind of elastic connective tissue that attaches muscles to bones.

What is the purpose of the wrist?

In most textbooks you'll find the wrist's purpose stated as: "The wrist ( and hand) allow for the manipulation of objects in space and provide us with the dexterity required for fine motor skills.".

What is the osteology of the wrist?

Osteology of the Wrist: The wrist is the junction of the distal end of the radius/ulna and the adjacent carpal bones. It is often compared to the ankle joint (s) in structure, however through evolution, the wrist has become more delicate and lost many of the characteristics that would allow it to be a truly effective weight-bearing joint.

What are the ligaments in the wrist?

There are many ligaments in the wrist joint, and rather than name them all, we can group them into two categories: Dorsal Intercarpal Ligaments: A series of ligaments that extend transversely across the dorsal (back) surface of the wrist connecting the carpals to one another and the carpals to the radius/ulna.

What is the hypermobile radiocarpal joint?

For this reason, often the radiocarpal joint is hypermobile (extra flexible), bordering on unstable , and is very susceptible to injury. This joint also allows a side to side glide which causes the hand and wrist to "tilt" left and right into radial deviation and ulnar deviation.

Which joint allows the hand and wrist to move down and up?

The proximal row of carpals is convex on the concave radius. This joint allows the hand and wrist to move down (palmar flexion) and up (extension or dorsiflexion). In gymnastics/acrobatics/yoga, more extension is required than most other sports as weight bearing forces the wrist into that position.

What is radiocarpal joint?

The radiocarpal joint: This is the intersection of the distal end of the radius and the proximal row of carpals (as described above). It is a true synovial joint, meaning that there is a joint capsule containing lubricating fluid within. The proximal row of carpals is convex on the concave radius.

What is the position of the forearm that allows the wrist to pronate?

This is best described as a "pivot" joint and allows (in conjunction with the proximal radioulnar joint at the elbow) the forearm to pronate (turn down) and supinate (turn up). The stability of this joint is essential for any weight bearing on the hand and wrist as it creates the "mortice" for the proximal carpals.

What are the tendons in the wrist?

Anatomy 101: Wrist Tendons. Tendons are fibrous cords that are similar to a rope, attached to muscles and bone. The tendons that control movement in your hands, wrists and fingers run through your forearm. There are 6 tendons that help move your wrist. The wrist tendons are:

Which tendon works to straighten the wrist?

It also helps bend the wrist in the direction of the thumb. Extensor carpi ulnaris: This tendon works with the ECRB and ECRL to straighten the wrist.

Which tendons work together to bend back the wrist?

Extensor carpi radialis brevis: This is one of 3 tendons (along with the next two on this list) that work together to bend back the wrist. It starts in the forearm and travels to the thumb side of the wrist, attaching to the base of the hand bones.

Which tendon bends the wrist?

Flexor carpi ulnaris: This is the other tendon that bends the wrist. It attaches to the pisiform, another wrist bone, and to the 5th hand bone. Palmaris longus tendon: This tendon is unique because only 3/4 of the population has it. For those who do have it, it can vary in size.

What are the two tendons that help move the wrist?

There are 6 tendons that help move your wrist. The wrist tendons are: Flexor carpi radialis: This tendon is one of two tendons that bend the wrist. It attaches to the base of the second and third hand bones. It also attaches to the trapezium, one of your wrist bones. Flexor carpi ulnaris: This is the other tendon that bends the wrist.

Which direction does the wrist tendons move?

It differs from these other two tendons in that it moves the wrist in the direction of the pinky rather than the thumb. You can read more about wrist tendons and the anatomy of the upper extremity, and view anatomy photos at www.HandCare.org. You can also learn about common hand/finger, wrist, arm and shoulder conditions or injuries.

Can you live without a tendon?

For those who do have it, it can vary in size. It is, however, a tendon you can live without because it has very little function in the hand and wrist. This tendon is often used to repair other tendons since it serves such a small purpose.

Osteology Wrist Anatomy

Osteology Wrist Anatomy consists of 8 carpal bones that’s arranged in two rows, the proximal row which contains from lateral to medial ( scaphoid, lunate, triquetrum, and pisiform ), while the distal row contains the following from lateral to medial ( trapezium, trapezoid, capitate, and hamate ).

Radiocarpal joint

Ellipsoid shape involving distal radius and the scaphoid, lunate, and triquetrum. It’s located at the level of the crease of proximal wrist flexion.

Midcarpal Joints

The midcarpal joint lies between the two rows of carpal bones. It is referred to as a “compound” articulation because each row has both a concave and a convex segment. wrist flexion, extension, and radial deviation are mainly midcarpal joint motions.

Thumb CMC Joint

The thumb is the most important digit of the hand and greatly magnifies the complexity of human prehension. Functionally, the sellar (saddle-shaped) Thumb CMC Joint is the most important joint of the thumb and consists of the articulation between the base of the first metacarpal and the distal aspect of the trapezium.

Other CMC Joints

The distal borders of the distal carpal row bones articulate with the bases of the metacarpals, thereby forming the CMC joints. The CMC articulations of the fingers permit only gliding movements.
