Nerves
Nerves are thread-like structures that form a network of pathways that transmit information from the brain to the body and the body to the brain, in the form of electrical impulses.

How do you feel texture with your fingers?
There are sensory neurons on your fingers and all over your body, which then goes to your interneuron in your spinal cord, then it sends a message to your brain.
Are gap junctions chemical synapses?
Gap junctions are connections between cells and some do pass ions from one cell to another cell. Some are chemical, some are electrical synapses ans some are direct connections.
A neuron is a single unit of nerve fiber. Most neurons jobs are to allow chemical and electrical impulses to pass from one part of the body to the other. Neurons in the brain function the same way, sending impulses back and forth.
What are the basic principles of somatic motor pathways?
The basic "principal" behind somatic motor pathways is a pathway from your "brain" or regions in or near the brain where nerve impluses travel from and go to skeletal muscle to cause a muscle contraction. (It's complicated, but doesn't get any more basic than this) -Jordan Bourne
What is the area in the eye where the optic nerve leaves the eyeball?
The fovea isnt the answer. Fovea is the area that has the most acute focus. The place the optic nerve leaves the eye is known as the BLIND SPOT.-jericho
Hair is dead cells and actually has no nerves. When you pull on your hair, it is actually the living nerves in your scalp which register it.
S1-5. These nerves enter through the sacral or pelvic vertebrae.
Which of the following does not receive branch fibers of the vagus nerves?
Inferior hypogastric plexus
Do dendrites receive chemical or electrical messages from other cells?
both, but usually biochemical since the synaptic gap is normally too wide for bioelectrical signals to cross.
Does the Vagus nerve carry nerve impulses that decrease the heart rate?
The vagus nerve releases the neurotransmitter, aceytlcholine, that slows down the heart rate. It is not the nerve impulses per se that do this, rather it is the the release of transmitter and it's interaction with post-synaptic receptors that have this effect.
What is responsible for transmission of nerve impulse across a synapse?
NEUROTRANSMITTER is responsible for transmission of nerve impulses.Eg.dopamine,acetylcholine etc.
Can you fix the phrenic nerve?
The phrenic nerve may be fixed if damaged, but one of the only successful treatments is surgery. Recovery may take a long time, depending on the person's immune system.
How do you heal radial nerve damage in cats?
Go to the vet.
Prognosis depends on the severity of the damage. See here for further info:

Could an injury to the wrist cause a piched nerve to the cervical area?
Thank you for your question. My answer is "No."
However, an injury to the cervical spinal nerves or those even lower, like an injury to the axillary (armpit) nerves or those in the elbow region can cause the symptoms of a pinched nerve with pain in the wrist. Pain would be located at the nerve injury or down the limb from the injured nerve. The only way a wrist injury could possibly cause a pinched nerve to your cervical region is if your wrist injury caused you to hold your wrist in a position that would strain your neck and pinch the nerves there. Very difficult to do.
Where is the hillock of the neuron?
The nerve cell hillock is the beginning of the axon immediately after the soma. This is where the action potential originates.
The parasympathetic nervous system has long preganglionic and short postganglionic fibers
