Exam 2 BIOS 252 Chamberlain University Questions and Answers
Rostral - Answer- towards the forehead
Caudal - Answer- toward the tail or spinal cord
reticular formation - Answer- a nerve network in the brainstem that plays an important role in controlling arousal
reticular activating system - Answer- Located in the upper brain stem; responsible for maintenance of consciousness, specifically one's level of arousal.
Cerebellum function - Answer- the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance BALANCE
Hypothalamus function - Answer- 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 - Answer- mammillary, tuberal, supraoptic, preoptic
frontal lobe - Answer- The lobe at the front of the brain associated with movement, speech, and impulsive behavior. (primary motor lobe)
parietal lobe - Answer- receives sensory input for touch and body position (primary sensory area)
occipital lobe - Answer- visual cortex
insula - Answer- regions of cortex located at the junction of the frontal and temporal lobes Thalamus - Answer- 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 - Answer- gray matter on the outside, white matter on the inside
spinal cord - Answer- gray matter on the inside, white matter on the outside
Dreams - Answer- a sequence of images, emotions, and thoughts passing through a sleeping person's mind (REM SLEEP)
Wernicke's area - Answer- 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 - Answer- 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 - Answer- Attach directly to the brain and can be motor, sensory, or both
sensory cranial nerves - Answer- 1, 2, 8 (I,II,VII)
motor cranial nerves - Answer- 3, 4, 6, 11, 12 (III,IV,VI,XI,XII)
oculomotor, trochlear, abducens, accessory, hypoglossal
mixed cranial nerves - Answer- 5, 7, 9, 10 (VVII,IX,X)
5 branches of facial nerves - Answer- temporal, zygomatic, buccal, mandibular, cervical
cranial nerve goes to innervate abdomen and thorax - Answer- visceral nerve
Divisions of the ANS - Answer- sympathetic and parasympathetic
sympathetic nervous system - Answer- the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations, fight or flight
parasympathetic nervous system - Answer- rest and digest; the division of the autonomic nervous system that calms the body, conserving its energy
adrenal cortex - Answer- the outer portion of the adrenal glands
adrenal medulla - Answer- secretes epinephrine and norepinephrine
Acetylcholine (ACh) - Answer- enables muscle action, learning, and memory
