The dorsal root of a spinal nerve contain what?
axons of sensory neurons
What type of nerve fibers are found in the ventral ramus of a spinal nerve?
The ventral ramus of a spinal nerve contains both sensory and motor nerve fibers. These fibers innervate the muscles, joints, and skin on the front part of the body.
What type of fibers make up the posterior and anterior roots of the spinal nerve?
Both Afferent and Efferentboth sensory and motorContains motor & sensory fibers!The spinal cord consists of nerve fibers that are afferent and efferent.
Afferent nerve fibers enter the part of the spinal cord called?
Afferent nerve fibers enter the spinal cord through the dorsal roots.
Spinal nerve contains both motor and sensory nerve fibers for 2-way communications?
yes
Fiber type in anterior ramus?
alpha spinal motor neuron axons leave the spinal column and enter the nerves via the ventral rami.
A spinal nerve is made of .?
Spinal nerves (aka mixed spinal nerves) are formed from the dorsal and ventral roots coming out of the spinal cord.A spinal nerve is made of mixed nerves. They have both sensory and a motor aspect. The roots of sensory fibers are on the dorsal side of the spinal cord.
What spinal nerve is made of?
Spinal nerves (aka mixed spinal nerves) are formed from the dorsal and ventral roots coming out of the spinal cord.A spinal nerve is made of mixed nerves. They have both sensory and a motor aspect. The roots of sensory fibers are on the dorsal side of the spinal cord.
Where can both sensory and motor fibers be found together?
Mixed nerves like the spinal nerves have both sensory afferents and motor efferents.
What cranial nerve motor fibers to sternocleidomastoid and trapezius?
The sternocleidomastoid and trapezius muscles are controlled by the accessory cranial nerve. Some call it cranial nerve XI.
Difference between dorsal ramus and dorsal root?
The roots are two split bases of spinal nerves that connect to the spinal cord. The rami are branches of the spinal nerve that form a complex system throughout the body with the two primary ones being the dorsal (posterior) ramus and the anterior ramus. A diagram would look like an x with the two roots coming together from the spinal cord to go through the intervertebral forming a spinal nerve then splitting again immediately after the intervertebral foramen forming the rami of the spinal nerve
What nerve carries only sensory fibers?
nerves carrying just sensory fibers are referred to as sensory and or what nerves?
