Document Summary

Face and hands forward: planes, frontal/ coronal, sagittal, transverse, movements, anterior- forward, posterior- backward, medial- inward, lateral- outward, superior- upward. Its job is to move in multiple trajectories and ways: muscle information, muscles shorten to about 1/3 of their length, origin, the point of attachment of the least mobile element. Isotonic: muscle contracts and elongates, making kinetic movements. Isometric: think a plank, muscle contraction but working, co-contraction of agonists and antagonists, multiple activity in the absence of movement. Lecture 2: face, oral cavity, pharynx, larynx, ues & esophagus, trachea, lungs, abdomen, face, the anterior surface of the head. Inhale: close larynx to build pressure, open larynx while forcefully exhale, larynx is the only place where you can build air pressure at. Sphincter: a ring-like with fibers that constantly go in a circle, smaller in diameter when contracted, your esophagus is condensed tube until the upper esophagus sphincter does its jobs, the upper esophageal sphincter.
