Document Summary

Smell, bypasses everything and goes straight to limbic system. Total area is approximately 2. 5 cm/sq. inch in each nasal cavity. Life of sensory cells is approximately 30 days, and approximately 1% is lost yearly. 3 characteristics of substance; volatile, water and lipid soluble. Mucus made of water and fats. Provide organism with the ability to move around the world it lives in. The ability to move its own body. Movement : to perform a movement we need to know: The present length (muscle spindles) of the muscle it will move 1a afferent neuron. The present tension (golgi tendon organ) in the muscle it will move 1b afferent neuron. Proprioceptors: muscle spindle and golgi tendon organ. Tendon in series with muscle and tendon; information about tension within the muscle. A receptor specialized sensory nerve ending. An afferent neuron propagate sensory impulses. A motor neuron - innervates the effector organ.
