What else can I help you with?
The anterior root of the spinal cord is composed of?
motor fibers
The anterior root and the posterior root fuse to form?
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
What is located outside the brain and spinal cord?
anterior root
Where are neurosomas of the anterior root located?
Neurosomas of the anterior root are located within the grey matter of the spinal cord. They consist of cell bodies of motor neurons that project their axons out of the spinal cord to innervate muscles and glands.
Where along a reflex arc would you find association neurons?
From the posterior root ganglion to the anterior horn of the spinal cord.
What is the difference between the dorsal root the ventral root and the dorsal root ganglion?
Ventral root is the ventral portion of spinal cord,there is no ganglion,cell body is of motor types ,cell info goes out of spinal cord of anterior horn. dorsal root is dorsal portion of spinal cord,it posses ganglion,cell body is of sensory types,information goes into spinal cord posterior horn
Where does synapses occur in the spinal cord?
Cell body of sensory neuron - in dorsal root ganglion. Cell body of motor neuron - in anterior gray horn.
Structures form by the fusion on the anterior root and posterior nerve root?
Spinal nerve.....
At t10-T11 there is a central disc bulge which indents the anterior thecal sac and abuts the cord?
Herniated disks can compress the spinal cord as the nucleus pulposa pushes out forward (anteriolaterally) and can cause spinal root compression. This can lead to unilateral deficit causing weakness.
Spinal cord flattened ventrally due to intermittent impingement?
Spinal Stenosis is a degenerative process on the spinal cord. Narrowing of the spinal canal begins to the flattened the spinal cord resulting in root nerve compression.
Are neurosomas of the anterior root located in the gray matter?
Yes, neurosomas of the anterior root are located in the gray matter of the spinal cord. The gray matter contains cell bodies, dendrites, and unmyelinated axons, whereas the white matter consists mostly of myelinated axons.
What part of the brain is located outside the cranium?
The spinal cord is part of the central nervous system that extends from the brainstem to the lower back and can be considered outside the cranium. It is housed within the spinal canal of the vertebral column.
