The central nervous system consists of the?
The central nervous system consists of the brain and spinal cord. The nerves leading from the spinal cord make up the peripheral nervous system.
What advantages are associated with the spinal cord and spinal nerves nerves functioning below the level of consciousness?
You can have and you have the reflex arc situated spinal cord level. The function of the reflex arc can not be overemphasized. This reflex withdrawal from the harmful stimulus protects you to great extent. Secondly the spinal cord is well placed away from the brain. So that the arrangement of nerves in your brain becomes less complicated.
How spinal nerves connected to the spinal cord?
dorsal and ventral roots.Each spinal nerve is attached to the spinal cord via 2 dorsal roots and 2 ventral roots. The term "spinal nerve" actually refers to the location where these 4 roots come together outside of the spinal cord.
How does damage to the spinal cord affect the nerves in the body?
Damage to the spinal cord can disrupt the communication between the brain and the nerves in the body, leading to loss of sensation, movement, and function below the level of injury. This can result in paralysis, loss of reflexes, and other neurological impairments.
Why people don't have any sensations below their shoulder with broken neck?
The spinal cord in your neck connects all of your nerves (therefore your sense of touch) to your brain...if this becomes damaged or severed, the nerves below it cannot transfer the electric signal to your brain to
Why are there 31 pairs of spinal nerve yet you only have 30 vertebrae?
There are 31 pairs of spinal nerves because the first cervical nerve exits above the first cervical vertebra. The remaining spinal nerves exit below their corresponding vertebrae. Therefore, there is one more pair of spinal nerves than there are vertebrae in the spinal column.
What is the conus medullaris attaching to?
The conus medullaris is the terminal end of the spinal cord. It occurs near lumbar nerves 1 (L1) and 2 (L2). After the spinal cord terminates, the spinal nerves continue as dangling nerves called the cauda equina. The upper end of the conus medullaris is usually not well defined.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.
what consists the peripheral nervous system?
-cranial nerves: which are located on the brain and carry impulses to the head and neck -spinal nerves: which extend from the spine and provide information to areas of the body below the neck -autonomile nerves: which responsible for involuntary body functions such as breathing and digestion
What is conus at L1?
The conus medullaris at L1 refers to the tapered end of the spinal cord, which typically terminates at the level of the first lumbar vertebra (L1) in adults. Below this point, the spinal nerves continue as a bundle called the cauda equina. The conus medullaris is significant because it marks the transition from the spinal cord to the peripheral nerves, and any injury or disease affecting this region can lead to neurological deficits.
