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.

Are nerves everywhere on the human body?
yes their is nerves in are body because if we don't have nerves in are body we won't be to scard watching t.v or other things .
C1-8. These nerves enter from the eight cervical or neck vertebrae.
What is the majority of all afferent pathways pass through and synapse with neurons?
The motor neuron is the final common pathway for all neurons to travel to complete their synapse. Afferent neurons or unipolar neurons all pass through the cord and brain on this journey.
What is the PNS glial cell that surrounds neuron cell bodies in ganglia?
In this case it is satellite cell. In the PNS system there are only two types of cells which are in the neural structures outside the CNS, Schwann Cells and Satellite cells. The Satellite cells surround neuron cell bodies in ganglia.
How do schwann cells in the peripheral nervous system repair damaged nerves?
forminga cellular cord that directs axonal regrowth.
How do the nodes of Ranvier differ from other segments of the same axon?
The nodes are more permeable to ions
The venom of the black widow spider causes violent muscle contractions by flooding synapses with?
It floods the synapses with Acetycholine or ACh.
The interior surface of a cell membrane of a polarized neuron is negatively charged due to the presence of large molecules like proteins and nucleic acids. This negative charge creates an electrical gradient that helps maintain the resting membrane potential of the neuron. In contrast, the external environment is more positively charged in comparison.
How the maintenance of a polarized state in a resting nerve is provided?
Maintenance of a polarized state of a resting nerve is achieved through continuous expenditure of energy.
What is the function of the vasomotor center?
vasomotor centre is under medullary control and is responsible for vasoconstriction /vasodilatation so that blood pressure is maintained.
How do you get rid of a pinched nerve from the foot?
You should first see a doctor to confirm you truly have a pinched nerve in your foot. if it is a pinched nerve, avoid all strenuous activity until the pain subsides. Often, taping or bandaging the foot for a few days will take care of the problem.
