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.
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
What branch of the spinal nerve contain autonomic fibers?
The rami communications
What carries impulses from the cns to the effectors?
Eletrical impulses throughout the nervous system
What makes up your nervous system?
The nervous system consists of the brain and the spinal cord. Nerve fibers of the spinal cord spread out to the different part of body. These nerve fibers are part of the peripheral nervous system and are the nerves that are found outside the spinal cord and brain.
Nerve fibers in what division of the autonomic nervous system arise from the brainstem and the sacral region of the spinal cord?
Brain
What is another name for parasympathetic?
The parasympathetic division is also called the craniosacral division because it arises from te brain and sacral region of the spinal cord; its fibers travel in certain cranial and sacral nerves.

What fibers do ventral spinal cord roots contain?
The ventral roots contain motor fibers.
Does the spinal cord have a backbone?
The spinal cord is a bundle of nerve fibers which is inside of the vertebrae (backbones).
What part of the spinal nerve consists of motor fibers leaving the spinal cord?
The ventral root.
The gray matter of the spinal cord?
Is located within the spinal cord and contains unmyelinated fibers.
What does a pelvic splanchnic nerve contains?
Preganglionic parasympathetic fibers. In the Parasympathetic division, the preganglionic axons leave the ventral roots of the spinal cord and collectively form the pelvic splanchnic nerves.
Does the proximal end of the spinal cord attach to the cerebellum?
no
The anterior root of the spinal cord is composed of?
motor fibers
Which structure is a bundle or group of nerve fibers located within the brain or spinal cord?
a tract is a bundle or group of nerve fibers located within the brain or spinal cord
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
