NEURON FUNCTION WORKSHEET ACTUAL
EXAM PAPER 2026 QUESTIONS WITH
ANSWERS GRADED A+
◍ Why are most cancers gliomas?.
Answer: glial cells never stop dividing
◍ - unidirectional - ATP independent- conducted by sliding, polimerizing, and
protein interacting.
Answer: slow axonal transport
◍ During the rapid depolarization of an action potential, the plasma membrane
is more permeable to (sodium/ potassium).
Answer: sodium
◍ Purkinje fibers/ multipolar neruons.
Answer:
◍ axon function.
Answer: send signal from the neuron to the next cell
◍ soma.
Answer:
◍ slow axonal transport.
Answer: SCa - neurofilaments and microtubulesSCb - polypeptides from
cytoskeletal proteins like actin to soluble enzymes of intermediary
metabolism.
◍ The function of the sodium-potassium ion exchange pump is to.
Answer: maintain the resting membrane potential (RMP)
◍ sodium permeability.
Answer: 1
, ◍ axon.
Answer:
◍ Peripheral demyelination: a. typically effects small diameter axons before
large diameter axons. b. is a characteristic feature of multiple sclerosis c.
affects the structure of oligodendrocytesd. typically affects schwann cells of
large, well-myelinated axonse. typically affects the axon at the ventral root
of the spinal cord..
Answer: d. typically affects Schwann cells of large, well-myelinated axons.
◍ The repolarization phase of action of action potentials in neurons is due
primarily to the flow of.
Answer: potassium flowing out of the cell.
◍ in a(n) ______ synapse, current flows directly between cells..
Answer: electrical
◍ at a _______ synapse, a neurotransmitter is released to stimulate the
postsynaptic membrane.
Answer: chemical
◍ -mostly in sensory components like the RETINA- associated with sensory
processing.
Answer: bipolar
◍ Functionally, which cellular location is the neuron's "decision-making site"
as to whether or not an action potential will be initiated?.
Answer: the axon hillock
◍ Schwann Cells.
Answer: produce myelin in PNS
◍ For a neuron with an initial membrane potential at -70, an increase in the
movement of potassium ions out of that neuron's cytoplasm would result in
the.
Answer: hyper polarization of a cell
◍ Axon terminals function.
