BANK COMPLETE QUESTIONS AND
ANSWERS GRADED A+ 2026
⩥ Sensory input function(PNS). Answer: Gathers information by
detecting changes(light, sound, any changes in and out of the body)
Once stimulated information is carried by sensory receptors to the CNS
as an sensory impulse
⩥ Interneuron. Answer: Transfers information from one part of the CNS
to another only in CNS
⩥ Integrative function. Answer: Coordinates sensory information to
create sensations, memory, thoughts
Makes decisions on body's response to sensory information
Intergration occurs in the interneurons
⩥ motor neurons (efferent). Answer: Transfer instructions from the CNS
to effectors(muscle or gland)
⩥ Divisions of PNS. Answer: somatic and autonomic
, ⩥ somatic nervous system. Answer: the division of the peripheral
nervous system that controls the body's skeletal muscles
⩥ autonomic nervous system. Answer: The part of the PNS that controls
the glands the smooth muscles, and cardiac muscles of the internal
organs
⩥ cells of the nervous system. Answer: neurons and neuroglia
⩥ Neuron. Answer: a nerve cell; the basic building block of the nervous
system vary in shape and size
⩥ cell body (soma or perikaryon). Answer: Central portion of the neuron
contains the nucleus, cytoplasm, organelles, neurofilaments,
chromatophilic substance(nissal bodies in RER) very unique to neurons
⩥ Dendrites. Answer: Short and branched receptive surfaces
Many per neuron
Receptive part of the neuron
Carries impulses toward the cell body
⩥ Axon. Answer: One per neuron, long thin process, carries impulses
away from the cell body
