Brain Anatomy and Function Revision
Questions with Complete Solutions
|Latest Update 2024
brain stem - ANSWER important processing center and relay station for info headed to or
from cerebrum or cerebellum
eeg - ANSWER electroencephalogram
cerebrospinal fluid - ANSWER supports brain and transports nutrients, chemical messengers,
and wastes
which meningitis is more deadly? - ANSWER bacterial
fold in brain - ANSWER gyri
depressions in brain - ANSWER sulci
Central Nervous System - ANSWER brain and spinal cord
Peripheral Nervous System - ANSWER everything except brain and spinal cord; divided into
Somatic Nervous Sytem and Autonomic Nervous System
Somatic Nervous Sytem - ANSWER [part of Peripheral Nervous System that] moves skeletal
muscles
Autonomic Nervous System - ANSWER [part of Peripheral Nervous System that]
moves smooth/cardiac muscles and affects fat and glands
, gray matter - ANSWER neuron cell bodies (lines outside of brain)
white matter - ANSWER neuron axons (inside of brain)
neuroglia - ANSWER aka glial cells; support neurons by regulating environment and destroying
pathogens; several types exist
sensory neurons - ANSWER afferent; pick up on external or internal
environments ex: taste, pain. touch
motor neurons - ANSWER efferent; cause movement of smooth, skeletal, or cardiac muscle
interneurons - ANSWER only in brains and spinal cord; link nerves in reflex arch, may play a
role in memory
dendrite - ANSWER [part of neuron that] receives message
cell body - ANSWER [part of neuron that] contains organelles
nissl body - ANSWER [part of neuron that] clusters rough ER and free ribosomes; makes
cell body appear gray
axon - ANSWER [part of neuron that] continues messages to synaptic terminals
action potential - ANSWER actual message that's being sent though a neuron
resting potential - ANSWER neuron is polarized; Na(+) on outside and K(-) on inside
