Where are interoceptors found? ------------Correct 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? ------------
Correct Answer--------------------muscle spindles
These are located at the junction of a tendon and a muscle ------------Correct
Answer--------------------tendon organs
These neurons conduct impulses from somatic receptors into the brain or spinal
cord ------------Correct Answer--------------------First-order neruons
These neurons conduct impulses from the brain stem and spinal cord to the
thalamus ------------Correct Answer--------------------second-order neurons
,These neurons conduct impulses from the thalamus to the primary
somatosensory area of the cortex on the same side ------------Correct 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 ------------Correct Answer--------------------
posterior column-medial lemniscus
Nerve impulses fro pain, temperature, itch, and tickles ascend to the cerebral
cortex along the ________________________ pathway ------------Correct Answer--
------------------anterolateral
Nerve impulses for most somatic sensation from the face, nasal cavity, oral cavity
etc, ascend tot he cerebral cortex along the ______________________ pathway --
----------Correct 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 ------------
Correct Answer--------------------trigeminothalamic
Where is the primary somatosensory area located ? ------------Correct 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 ------------Correct Answer--------------------
direct motor pathways
Where is the primary motor area located ? ------------Correct 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 ------------Correct 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 ------------Correct Answer--------------------the
cerebellum
What are the integrative functions of the cerebrum? ------------Correct Answer------
--------------cerebral activities (sleep & wakefulness), learning, memory, emotional
response
between the origin and insertion which is usually located proximally in limbs ? -----
-------Correct Answer--------------------Origin
What happens during REVERSE MUSCLE ACTION? ------------Correct Answer----------
----------specific movements of the body the actions are reversed THEREFOR the
positions of the origin and insertion of a muscle are switched
What is a mechanical advantage using the example of a lever? ------------Correct
Answer--------------------if the load is closer to the fulcrum and the effort is farther
from the fulcrum only a small about of effort is needed to move the load
Bones serve as levers and joints serve as ________ for the lever ------------Correct
Answer--------------------fulcrum
