UPDATED QUESTIONS AND ANSWERS
◉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
◉These neurons conduct impulses from the brain stem and spinal
cord to the thalamus Answer: second-order neurons
◉These neurons conduct impulses from the thalamus to the
primary somatosensory area of the cortex on the same side Answer:
third-order neurons
◉Nerve impulses for touch, pressure, vibration, and conscious
proprioception from the limbs, trunk, neck,, and posterior head
ascend to the cerebral cortex along the __________________________
pathway Answer: posterior column-medial lemniscus
