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

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
,3|Page
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
, 4|Page
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
Nerve impulses fro pain, temperature, itch, and tickles
ascend to the cerebral cortex along the
________________________ pathway - ANSWER-
anterolateral
Nerve impulses for most somatic sensation from the face,
nasal cavity, oral cavity etc, ascend tot he cerebral cortex
along the ______________________ pathway -
ANSWER-trigeminothalamic
The axons of the second order neurons cross tot he
opposite side of the pons and medulla and then ascend as
the ____________________________ tract - ANSWER-
trigeminothalamic
