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
,2|Page
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
Where is the primary somatosensory area located ? - ANSWER-the postcentral gyri of the
parietal lobes of the cerebral cortex
These motor pathways provide input to lower motor neurons from axons that extend directly
from the cerebral cortex - ANSWER-direct motor pathways
______________ 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
, 3|Page
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
Where is the primary motor area located ? - ANSWER-precentral gyrus of frontal lobe
What are these the functions of ?
-play large role in initiation and termination of movements
- suppress unwanted movements
- influences muscle tone
-influences many aspects of cortical function - ANSWER-Basal Nuclei
What part of the CNS has these functions?
- monitoring intention for movements
-monitoring actual movement
- comparing command signals with sensory information
- sending out corrective feedback - ANSWER-the cerebellum
