Musculoskeletal and Endocrine Q & As
(Verified Answers) 2026
Peripheral Nevous System (PNS) - Correct Answers ✅12
pairs of cranial nerves and 31 spinal nerves
PNS - Correct Answers ✅somatic nervous system and
autonomic nervous system
afferent nerves - Correct Answers ✅Also called sensory
nerves; nerves that carry impulses from cells, tissue, and
organs back to CNS via sensory receptors.
efferent nerves - Correct Answers ✅Also called motor
nerves; nerves that carry information out of the CNS to other
areas of the body (cells, tissues, and organs).
Neuron - Correct Answers ✅a nerve cell; the basic building
block of the nervous system
-uses glucose as fuel source
Parts of a neuron - Correct Answers ✅cell body, dendrites,
axon
CNS cell bodies - Correct Answers ✅-where most cell
bodies are found

Pathophysiology Neurologic System,
Musculoskeletal and Endocrine Q & As
(Verified Answers) 2026
-grouped together are called nuclei
ganglia or plexus - Correct Answers ✅-cell bodies groups in
PNS
Dendrites - Correct Answers ✅Branchlike parts of a neuron
that are specialized to receive information and direct it to the
cell body.
The Axon - Correct Answers ✅the extension of a neuron,
conducts impulses to other neurons or to muscles or glands
Myelin Sheath - Correct Answers ✅-lipid material that
covers axons
-pillow cases on axon
-divided down the axon by nodes of Ranvier
Nodes of Ranvier - Correct Answers ✅Gaps in the myelin
sheath to which voltage-gated sodium channels are confined.
-where nutrient exchange occurs
Myelin Sheath - Correct Answers ✅how impulses flow
between nodes of Ranvier

salutatory conduction - Correct Answers ✅the propagation
of action potentials along myelinated axons from one node of
Ranvier to the next node, increasing the conduction velocity
of action potentials.
associational neurons - Correct Answers ✅also called
interneurons, largest in number, located in CNS
-transmit impulses from neuron to neuron
Cranial nerve I - Correct Answers ✅Olfactory (smell)
Cranial nerve II - Correct Answers ✅Optic - vision
Cranial nerve III - Correct Answers ✅Oculomotor (motor)
