BIOL 251 ANATOMY AND PHYSIOLOGY EXAM 2 - NERVOUS
SYSTEM AND NERVOUS TISSUE FUNDAMENTALS QUESTIONS
WITH CORRECT ANSWERS 2026 RATED A+
1. Nervous system functions-ANSWER- sensory input, integration, motor output
2. Sensory input-ANSWER- monitors changes inside and outside the body
3. Function of nervous system-ANSWER- sensory input-ANSWER- monitors changes inside and
outside the body
4. Function of nervous system-ANSWER- motor output (motor response)-ANSWER- nervous
system activates
Effector organs to cause a response
5. Effector organ-ANSWER- responsible for carrying out decision made by brain
6. Cell types in nervous system-ANSWER- neurons and neuroglia
7. Neurons-ANSWER-
8. Neurons-ANSWER- nerve cells that can respond to stimuli and transmit electric signals
9. Components of the Nervous System-ANSWER- central nervous system and peripheral nervous
system
10. Central nervous system-ANSWER- brain and spinal cord
Function
-ANSWER- is responsible for interpreting sensory input and deciding
Motor output
11. Peripheral nervous system-ANSWER- composed of bundles of nerves coming from the
brain/spinal cord
Function-ANSWER- spinal nerves and cranial nerves link rest of body to CNA
12. Peripheral nervous system divisions-ANSWER- afferent and efferent
13. Afferent-ANSWER- carrying impulses toward CNS
(arrive)- impulses allow cns to interpret information, send signal
14. Efferent-ANSWER- carry impulses from CNS to effector organs
, (exit)- impulses activate muscle or glands to carry out motor response
15. Astrocytes(CNS)-ANSWER- most abundant and versatile of the neuroglia- star shaped,
connecting to and wrapping around neurons, synaptic nerve endings, surrounding blood
capillaries
16. Major functions of astrocytes-ANSWER- -provide nutrient supply for neuron cells, allows
migration of young
Neurons, "clean up" outside neuron cells (eg; leaked K+ ions, neurotransmitters)
17. Microglial cell (CNS)-ANSWER- function-ANSWER- contact nearby neuron cells to monitor
health, migrate toward injured
Neurons, where they transform into a macrophage and phagocytize the neuron
Importance-ANSWER- immune system has very limited access to CNS

18. Ependymal cells(CNS)-ANSWER- most cells have cilia, line central cavities of CNS to circulate
and secret cere
Brospinal fluid within cavities
19. Oligodendrocytes(CNS)-ANSWER- associated with thicker nerve fibers in CNS, wrapping
around each fiber to
Produce myelin sheath, creates insulin cover for individual neurons allowing for fast and easy
transmission
20. Satellite cells (PNS)-ANSWER- support and protect neuron in PNS, functions similarly to
astrocytes
21. Schwann Cells (PNS)-ANSWER- surround nerve fibers of pns to form myelin sheaths,
function similar to oligoden
Drocytes
22. Neurons-ANSWER- cells of the nervous system specialized to generate or transmit electrical
signals (nerve impulses),
