how will nervous tissue help you pass this course

Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons. Brain, Spinal Cord, and nerves are composed of nervous tissue, they are specialized for being stimulated to transmit stimulus from one to another part of the body rapidly.

Full Answer

How will nervous tissue help you?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.

How do nerve cells help in passing information?

Neurons talk to each other using special chemicals called neurotransmitters. Neurotransmitters are like chemical words, sending “messages” from one neuron to another. There are many different sorts of neurotransmitters: some stimulate neurons, making them more active; others inhibit them, making them less active.

How does the nervous tissue take action?

The junction between neuron and the muscle cell is called neuromuscular junction. When a nerve impulse (information) reaches the muscles through the neuromuscular junction, the muscles show the action (response). The muscles show the action/response by contraction and relaxation of the special muscle proteins.

The four types of neuroglia found in the central nervous system are astrocytes, microglial cells, ependymal cells, and oligodendrocytes. The two types of neuroglia found in the peripheral nervous system are satellite cells and Schwann cells. Neurons are the other the other type of cell that comprise nervous tissue.

How do nerve cells communicate?

Nerve cells or neurons communicate with each other by releasing specific molecules in the gap between them, the synapses. The sending neuron passes on messages through packets of chemicals called neurotransmitters, which are picked up by the receiving cell with the help of receptors on its surface.

How do nerve cells operate and communicate?

Nerve cells communicate by using electrical signals. Dendrites, the widely branched portion of the neuron, receive signals from other neurons and then transmit them over a thin cell extension -- the axon -- to other nerve cells. Axon and dendrites are usually interconnected by the neuron's cell body.

What part of the brain controls decision making?

Frontal lobeFrontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement.

Which part of the brain is responsible for memories language and intelligence?

The cerebrum (the outer layer is called the cerebral cortex), which is split into two hemispheres and is highly folded. It controls intelligence, personality, conscious thought and high-level functions, such as language and verbal memory.

What Is Nervous Tissue?

Nervous tissue is one of four specialized animal tissue types. Where is nervous tissue found? The nervous tissue location is in the central and peripheral nervous system in multicellular animals. Nervous tissue is important for sending messages throughout the body, which allow the body to interpret stimuli from the environment, move, adapt and process information.

What does the nervous system do to the body?

This helps our body monitor potential problems within our organ systems.

What are the two types of nervous tissue?

There are two main types of nervous tissue, neurons and neuroglia. These two types of cells fulfill different roles in the nervous system and can be found in different locations in the body. Next, let's look at the nervous tissue examples of neurons and neuroglia in detail.

What are the two main locations of the nervous system?

This can be in the central nervous system, or the peripheral nervous system. In the central nervous system, there are two main locations, the brain and spinal cord . The brain and spinal cord are made of nerves, white matter, and gray matter. The brains main function is to process information, acting like a central computer. The spinal cord sends messages between the brain and body. It is composed of long nerves that enter and exit through the vertebrae in the spinal column.

What are the different types of neurons?

Neurons are the cells of the nervous system. They facilitate the transfer of information throughout the body by sending electrochemical signals. Neurons make up the white and gray matter in the brain, and the nerves of the body. There are several different types of neurons including: 1 Interneurons 2 Sensory neurons 3 Motor neurons

What are the cells of the nervous system?

Neurons are the cells of the nervous system. They facilitate the transfer of information throughout the body by sending electrochemical signals. Neurons make up the white and gray matter in the brain, and the nerves of the body. There are several different types of neurons including:

What are the supporting cells of neurons?

Neuroglia are the supporting cells of neurons. They do not send electrochemical messages themselves, but rather create a healthy environment to support and protect neurons. Neuroglia are found in both the central and peripheral nervous system. Like neurons, there are several types of neuroglia:
