EXAM QUESTIONS AND ANSWERS
GRADED A+ 2025/2026
Rostral - ANS towards the forehead
Caudal - ANS toward the tail or spinal cord
reticular formation - ANS a nerve network in the brainstem that plays an important role in
controlling arousal
reticular activating system - ANS Located in the upper brain stem; responsible for
maintenance of consciousness, specifically one's level of arousal.
Cerebellum function - ANS the "little brain" at the rear of the brainstem; functions include
processing sensory input and coordinating movement output and balance BALANCE
Hypothalamus function - ANS A neural structure lying below the thalamus; it directs several
maintenance activities (eating, drinking, body temperature), helps govern the endocrine system
via the pituitary gland, and is linked to emotion and reward.
4 regions of hypothalamus - ANS mammillary, tuberal, supraoptic, preoptic
1 @COPYRIGHT 2025/2026 ALLRIGHTS RESERVED.
, frontal lobe - ANS The lobe at the front of the brain associated with movement, speech, and
impulsive behavior. (primary motor lobe)
parietal lobe - ANS receives sensory input for touch and body position (primary sensory area)
occipital lobe - ANS visual cortex
insula - ANS regions of cortex located at the junction of the frontal and temporal lobes
Thalamus - ANS the brain's sensory control center, located on top of the brainstem; it directs
messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum
and medulla (RELAY STATION BY OCCIPITAL LOBE)
brain - ANS gray matter on the outside, white matter on the inside
spinal cord - ANS gray matter on the inside, white matter on the outside
Dreams - ANS a sequence of images, emotions, and thoughts passing through a sleeping
person's mind (REM SLEEP)
Wernicke's area - ANS controls language reception - a brain area involved in language
comprehension and expression; usually in the left temporal lobe. Transmits speech to Broca's
Area
Broca's area - ANS Controls language expression - an area of the frontal lobe, usually in the
left hemisphere, that directs the muscle movements involved in speech.
12 pair of cranial nerves - ANS Attach directly to the brain and can be motor, sensory, or both
sensory cranial nerves - ANS 1, 2, 8 (I,II,VII)
