What kind of nerves carry impulses toward the cns?
Afferent
Why are some nerves called afferent nerves and others are called efferent nerves- how do they differ in function?
Afferent nerves are those that send impulses from the PNS to the CNS. Efferent nerves send impulses from the CNS to the PNS. So the first goes toward the Central Nervous System and the second goes away from it.
Can sensory nerves send information from your brain to your hand?
No , they send from hand to cns .
Sympathetic nerves exit the CNS through what nerves?
You have sympathetic trunks located by either side of vertebral column. You have thoracolumber out flow for sympathetic system. You do not have nerves for the same.
What are the three types of neuron?
Functional types of neurons: 1. sensory (afferent) neurons - input to CNS from sensory receptors; dendrites located at receptors, axons in nerves, cell bodies in ganglia outside the CNS 2. motor (efferent) neurons - output from CNS to effectors cell bodies and dendrites located in the CNS, axons in nerves 3. interneurons - communicate and integrate information within the CNS; located entirely within the CNS
Do most nerves within the cns never regenerate?
yes cranial nerves can regenerate
Are cns nerves able to regenerate?
False
Do Peripheral nerves regenerate?
If they are perfectly realigned through neurosurgery, there is a chance that they can regenerate. But we are not talking about an entire plexus of nerves.
Does massage therapy help facial muscles and nerves regenerate?
Massage therapy can help facial muscles and nerves regenerate by increasing blood flow to the area. Massage therapy alone will not regenerate muscles or nerves.
Does the CNS nerve fibers lack the intrinsic capacity to regenerate while PNS nerve fibers are able to regenerate?
Yes
What are the nerves that gather information from the environment and carry it to the CNS?
The sensory nerves
What part of the CNS gives rise to sympathetic nerves?
The parts of the CNS that give rise to sympathetic nerves are the thoracic and lumbar regions of the spinal cord.
What is the nerves that send messages from the CNS to internal organs?
Motor Neurones send the impulse from the CNS to the effector muscle
What kind of nerves carry impulses toward the cns?
Afferent
Nerves that transmit impulses to the CNS are called?
motor

An impulse reaches the CNS from the PNS via the?
Afferent nerves
