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 drugs affect the process of synaptic transmission?
They can act in a number of ways, both presynaptically and postsynaptically. They can affect how vescicles release neurotransmitters, how neurotransmitters are cleaved/reuptake, they can block receptors, destroy receptors, agonistically bind to receptors which mimics the neurotransmitter. These are a few.
Why electrical impulses are referred to as neural impulses?
Electrical impulses are referred to as neural impulses because a neural impulse cause electrical impulses. Neurons use electrical impulses to send messages.
Why does your bottom lip keep twitching for 2 weeks?
Probably due to the nerves. You can get Botox shots to help with that. If you are still having trouble see a physician.
What does the short end of a nerve fiber has?
Lol i betchaa all these questions are for some desperate student who hasnt listend in class and has got overdue homework.....just quietly...(Thats ME;)
C. Dendrites and axons both extend from the cell body of the neuron in a branching fashion.
ipsilaterally
What is the difference in transmission between myelinated and unmyelinated fibers?
Impulse transmission on an unmyelinated nerve fiber is much slower than the impulse transmission on a myelinated nerve fiber.
Can you have a tumor in the cranial nerve meninges?
Yes. you can have a Meningioma of the Optic Nerve.
When a nerve is stimulated, its cell membrane is depolarised so that the inside of the cell becomes less
negative. The potential is conducted along the axon to the axon terminal. At the dendrite it stimulates the
release of a chemical transmitter, which diffuses across a synapse. The transmitter binds to receptor sites
on the postsynaptic cell membrane to stimulate the generation of another impulse.
Do action potential cause electrical and chemical change in neuron?
Yes, you see when a action potential process is taking place the negative ions are in the center of the nerve and the positives are on the outside, during the action potential however they swap places, which in doing so changes the electrical and chemicals in the nerve cell.
How would you define the gap in the gap theory?
This gap is referred to as the service gap and is considered the most important because it determines the level of satisfaction/dissatisfaction with the service and, ultimately, the organization.
Is there a medical term for uncomfortable legs while trying to sleep besides restless legs?
Yes. It is called, Restless Leg Syndrome AKA RLS
