At the synapses, just below the brain, there is a tiny gap disconnecting them. A nerve impulse must first be sent, meaning a small electric shock sent through the synapses and body to wherever it's going. When the impulse arrives back, the shock is sent back up the synapses to the brain confirming it went to the right part of the body, causing a tic, knee-jerk reaction, something like that.

What does the nerve cell protective sheath do?
It serves the same function as insulation covering wire. It ensures the electric impluse is carried along quickly and efficiently.
What is retrobulbar neuritis?
Nerve damage that occurs in the section of the optic nerve located behind the eyeball
Sound which impinges on the inner ear and the auditory nerve arrives as a fairly meaningless stimulus At this point it should be viewed as?
perception
What occurs in the cochlea in the ear?
That is where the vibrations in the air are turned into a nerve signal and sent to the brain.
When nerve impulses pass to the diaphragm the diaphragm relaxes and exhalation occurs is this true or false?

Explain the way in which a nerve impluse is conducted from a sensory site to produce an effect?
the best way to answer this question is to attend your next scince leson.
What is somato somatic synapes?
This is a type of referred pain which occurs when sensory information comes to the spinal cord, but is interpreted by the brain and spinal cord as coming from another location. For example, when someone has sciatica, the pain is felt down the leg, when the origination point may be a pinched nerve in the lower spinal column.

What is a description of carpal tunnel syndrome?
Median nerve entrapment, at the wrist, occurs by swelling and compression of the tendon sheath containing this nerve.
What occurs when the respiratory center stops sending nerve signals to the diaphragm and the rib cage?
muscles relax and expiration occurs
Where does nerve conduction deafness occur?
Nerve conduction deafness is one of the two types of deafness that can happen. It occurs when there is a break in communication between the nerve cells and the inner ear.
What condition occurs when the median nerve in the wrist is compressed?
Carpal tunnel syndrome.
