What carries out these functions?
-control of the ANS
-production of hormones
-regulation of emotion and behavioral patterns and eating and drinking
- control of body temp
-regulation of circadian rhythms and states of consciousness - ANSWER-the dicephalon
which consists of the thalamus and the hypothalamus
the pineal gland is part of the ___________ system - ANSWER-endocrine
What are the roles of the epithalamus? - ANSWER--secrets melatonin via the pineal
gland
-regulates blood pressure, fluid balance, hunger, and thirst
_________ are folds that occur due to the gray matter of the cortex enlarging much
faster than the deeper white matter - ANSWER-Gyri
What kind of tract contains axons that conduct nerve impulses between gyris in the
same hemisphere? - ANSWER-association tracts
what kind of tract contains axons that conduct nerve impulses from gyri in one cerebral
hemisphere to corresponding gyri in other cerebral hemispheres? example = corpus
callosum - ANSWER-commissural tracts
, what is the name of the distorted map of the body located in the primary somatosensory
area? - ANSWER-the sensory homunculus
Where is the Broca`s speech area located? - ANSWER-the frontal lobe close to the
lateral cerebral sulcus
What brain waves when found in an awake adult represent brain damage? - ANSWER-
delta waves
What brain waves disappear during sleep? - ANSWER-alpha waves
What waves normally occur in people experiencing with emotional stress or disorders? -
ANSWER-theta waves
How many cranial special sensory nerves are there? - ANSWER-3
how many cranial motor nerves are there? - ANSWER-5
How many cranial mixed nerves are there? - ANSWER-4
These nerves carry axons of sensory neurons and are unique to the head with a cell
body located in ganglia outside the brain - ANSWER-special sensory nerves
______________ is the conscious or subconscious awareness of changes in the
external or internal environement - ANSWER-sensation
These sensory receptors are bare dendrites that lack any structural specialization.
Ex: receptors for pain, temp, itch, tickle - ANSWER-Free nerve endings
What kind of receptors are associated with visceral sensation such as pressure and
vibration? - ANSWER-encapsulated nerve ending
the sensation of hearing, visions, smell, taste, touch, pressure, vibration, temperature
and pain are all conveyed by ______________ - ANSWER-exteroceptors
Where are interoceptors found? - ANSWER-in blood vessels, visceral organs, muscles,
and the nervous system
What are the proprioceptors in skeletal muscles that are responsible for monitoring
changes in the length of the muscles in stretch reflexes? - ANSWER-muscle spindles
These are located at the junction of a tendon and a muscle - ANSWER-tendon organs
These neurons conduct impulses from somatic receptors into the brain or spinal cord -
ANSWER-First-order neruons
