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.
Does the ventral ramus contain only motor fibers?
True
Are efferent nerve fibers described as motor nerve fibers?
Yes.
The combination of a neuron and the muscle fibers it associates with is called?
Motor unit = the single motor neuron and the multiple muscle fibers that it innervates.
What is the term for nerves carrying both sensory and motor fibers?
Nerves carrying both sensory and motor fibers are called sensorimotor nerves.

Does the ventral ramus contain only motor fibers?
True
Is the glossopharyngeal nerve the only nerve that contains sensory fibers?
no
Spinal nerve contains both motor and sensory nerve fibers for 2-way communications?
yes
Is the glossopharyngeal nerve the only cranial nerve that contains sensory fibers?
no
What is the function of the glossopharyngeal?
It contains both sensory and motor fibers, and supplys the tongue soft palate, pharynx, and parotid gland.

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 is a motor unit is made up of?
Motor neurons and the muscle fibers they transmit signals toA motor unit is a collection of muscle fibers that contract as a single functional unit when stimulated by an impulse from a motor neuron. The actual size can vary greatly, from many large muscle fibers in the quadriceps muscle group per motor unit to just a few muscle fibers in the muscles of the fingers per motor unit.
Does the dorsal ramus consist only of motor fibers bringing information to the spinal cord?
False.
Does the oculomotor nerve have motor fibers?
Yes it is motor and parasympathetic.
Are efferent nerve fibers also described as motor nerve fibers?
yes
