Spinal nerves exiting the cord from the level of L4 to S4?
Spinal nerves exiting the cord from the level of L4 to S4 supply motor and sensory innervation to the lower extremities, including the buttocks, thighs, legs, and feet. They contribute to functions such as walking, standing, and bladder control. Damage to these nerves can lead to symptoms such as weakness, numbness, and pain in the lower body.
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.
What is the cause of quadriplegia?
quadriplegia occurs after damage to the upper spinal cord at the level of the shoulders or higher (the nerves controlling the arms leave the spine at that level).
What is the main cause of quadriplegia?
quadriplegia occurs after damage to the upper spinal cord at the level of the shoulders or higher (the nerves controlling the arms leave the spine at that level).
Are spinal nerves grouped and named according to their function?
They are numbered by the level on spinal cord: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal.
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.
Where is the nerve in your back or spine that controls the bladder?
The bladder receives information through the lumbar nerve plexus that is formed from spinal nerves that extend from the spinal cord and exit through the vertebral foramen (holes in between spinal bones )of the lower lumbar spine. Because the information comes from a nerve group, or plexus, it receives nerve impulse from more than one level of spinal cord. Thomas A. Bea
Is a newborn paralyzed immediately if it has Spina Bifida?
No, not necessarily. The level of paralysis is dependent on the level of the lesion, what vertebrae were affected and whether the lesion was open and the spinal cord and nerves were exposed.

What does neurobiology mean?
Neurobiology is the study of the nervous system, including the brain, spinal cord, and peripheral nerves, and how they function at the cellular and molecular level to regulate behavior, cognition, and other physiological processes. It seeks to understand how neural circuits are formed, how they communicate, and how they are altered in disease or injury.
What is the spinal cord terminus?
Not much information here in context to efficiently answer the question but I will try. The spinal cord generally ends (terminates) around the L1 vertebral level in the lumbar spinal column give or take a level or so in normal humans. After this, small spinal nerves continue down in a sac and exit the lumbar and sacral spine to innervate the pelvis and lower extremities.
