Is the humerus distal to the elbow?

The radial nerve has a long and tortuous course in the upper limb and lies in close proximity to the bone in the spiral groove, making it susceptible to injuries. The prevalence of radial nerve palsy following fracture of the humerus shaft is 11.8% [ 1 ], while incidence of iatrogenic injuries is approximately 4.2% [ 2 ].

What is the course of the radial nerve?

Course. The radial nerve lies posterior to the axillary artery in the axilla and enters the posterior compartment of the arm under teres major muscle via the triangular interval. In the posterior compartment of the arm, it winds its way around the spiral groove of the humerus, accompanying profunda brachii artery.Feb 2, 2022

Which part of humerus is a bone marking for radial nerve?

Posterior Markings of the Humerus Bone:

Radial groove or sulcus (Sulcus nervi) is a shallow depression that runs diagonally along the lateral posterior surface of the bone, next to the deltoid tuberosity. It forms a partial passageway for the radial nerve and deep brachial artery.

What landmark on the humerus articulates with the radius?

Immediately lateral to the trochlea is the capitulum (“small head”), a knob-like structure located on the anterior surface of the distal humerus. The capitulum articulates with the radius bone of the forearm.

Where is the radial groove of the humerus?

The radial sulcus (also known as the musculospiral groove, radial groove, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone.

What are the part of humerus?

The lower end of the humerus includes two smooth articular surfaces (capitulum and trochlea), two depressions (fossae) that form part of the elbow joint, and two projections (epicondyles). The capitulum laterally articulates with the radius; the trochlea, a spool-shaped surface, articulates with the ulna.

What is the radial fossa?

The radial fossa is a slight depression found on the humerus above the front part of the capitulum. It receives the anterior border of the head of the radius when the forearm is flexed.

Which bony landmark of the humerus articulates with the ulna to form the elbow joint?

trochlea
The elbow joint is formed by the articulation between the trochlea of the humerus and the trochlear notch of the ulna, plus the articulation between the capitulum of the humerus and the head of the radius. The proximal radioulnar joint is the articulation between the head of the radius and the radial notch of the ulna.

Is humerus axial or appendicular?

appendicular
Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.Nov 17, 2018

Which landmark is found on the distal end of the humerus?

The olecranon fossa is the large depression at the distal end of the humerus. The olecranon fossa of the humerus together with the olecranon process of the ulna permit full extension of the forearm.

What does the radius articulate with?

The radius articulates proximally at the elbow with the capitulum of the humerus and the radial notch of the ulna. It articulates at its distal end with the ulna at the ulnar notch and with the articular surfaces of the scaphoid and lunate carpal bones.Aug 8, 2021

Which bone articulates with the ulna quizlet?
