Watch this video (http://openstaxcollege.org/l/motorpathway) to learn more about the descending motor pathway for the somatic nervous system. The autonomic connections are mentioned, which are covered in another chapter. From this brief video, only some of the descending motor pathway of the somatic nervous system is described. Which division of the pathway is described and which division is left out?
Conformational changes in channel proteins brought about by voltage changes are responsible for opening and closing Na+ and K+ gates during the generation of an action potential. (True or false?)
Which of these locations is where the greatest level of integration is taking place in the example of testing the temperature of the shower? skeletal muscle spinal cord thalamus cerebral cortex

Benign Paroxysmal Positional Vertigo is a disorder where some of the calcium carbonate crystals in the utricle migrate into the semicircular canals. Why does this condition cause periods of dizziness? The hair cells in the semicircular canals will be constantly activated The hair cells in the semicircular canals will now be stimulated by gravity The utricle will no longer recognize acceleration There will be too much volume in the semicircular canals for them to detect motion.
Define an action potential.
