Sensory Nerve
myofobril
Myelinated Fibers.
Muscle cells are called 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.
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
Nerve cells called neurons sends messages from brain to body along fibers called axons.
myofobril
Dendrites
False. Afferent fibers carry the messages to the brain while Efferent fibers carry them to the CNS which then goes directly to the motor unit for a reaction to the stimulus.
i think the brain sends messages between different parts of the body.
Myelinated Fibers.
Muscle cells are called fibers.
Spinal Cord.
Usually they are simply called nerves. Depending on the scenario, sometimes they are called nerve tracts or pathways.
yes the dermis contains both elastic and collagen fibers
I also think that you may be thinking of how one half (or one side) of the brain carries messages to the other side. That is done with a wide, flat bundle of neural fibers called the corpus callosum.
no
