How does the brain and spinal cord work together?
Spinal nerves connect the brain with the nerves in most parts of the body. Other nerves go directly from the brain to the eyes, ears, and other parts of the head. This network of nerves carries messages back and forth between the brain and the rest of the body.
Which of the following best describes spinal cord?
The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. It encloses the central canal of the spinal cord, which contains cerebrospinal fluid.
What is it called when the brain spinal cord and nerves are working together?
The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts.
What part of the brain connects the brain to the spinal cord?
The brainstem is the lower extension of the brain, located in front of the cerebellum and connected to the spinal cord. It consists of three structures: the midbrain, pons and medulla oblongata.
What is the difference between brain and spinal cord?
The brain is housed inside the skull and it controls most of the activities of the body. … The spinal cord is made up of nerves that carry information between the brain and the rest of the body.
What is the structure and function of the spinal cord?
The spinal cord is part of the central nervous system. This long structure runs down the center of your back, and it mediates messages between the brain and the peripheral nerves. The spinal cord is primarily composed of nerves, which are organized in systematic pathways, also described as tracts.
What is spinal segment?
A spinal segment is defined by dorsal roots entering and ventral roots exiting the cord, (i.e., a spinal cord section that gives rise to one spinal nerve is considered as a segment.) (Figure 3.4). Figure 3.4. (A) Drawing of the spinal cord with its spinal roots.
