What does the ventral root of a spinal nerve do?
the ventral root carries motor response
Which spinal cord structure contains the axons of cns motor neurons that control muscle and glands?
ventral root
What would happen if the ventral root was cut?
ventral root from the ventral horn of the spinal cord is motor. If ventral root is cut it will lead to to a kind of paralysis called flaccid paralysis. This is because ventral horn contains lower motor neurons. As such the skeletal muscle innervated by the root is paralysed
Is ventral root a loss of motor function?
Yes, the ventral root of a spinal nerve is the efferent motor root, consists of axons of motor neurons. It joins the dorsal root to form a mixed spinal nerve, which consists of afferent sensory neurons (from the dorsal root) and efferent motor neurons (from the ventral root). Therefore severing the ventral root will result in a loss of motor function for the myotome supplied by that spinal nerve.
The motor root of the spinal nerve is also referred to as the?
ventral root
Fibers type in the ventral root?
motor
Are dorsal and ventral roots spinal nerves?
The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
What fiber type in ventral root?
Efferent or Motor
Sensory neurons enter the spinal cord via what root?
ventral root yo
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
An area of body insensitve to a pinprick would involve injury to what aspect of the nerve root?
You are speaking of sensation and sensation travels in the dorsal root. The fibers within that root that carry pin-prick sensation would most likely be the A-delta fibers
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
