Document Summary
Origin - stationary and proximal attachment where the muscle starts. Insertion - attachment where the muscle ends that moves and is distal. Wide layer of tendons to a narrow tendon. Several tendon at 1 end and only 1 on the other end. Can be described in 2 ways: referencing the bone affected in the movement (e. g. biceps brachii causes forearm, by referencing the joint involved in movement (e. g. biceps brachii causes flexion of flexion) the elbow) Verbal and nonverbal communication (laughing, frowning etc. ) 4 groups: muscles of head and neck. Functions palatal muscles raise the soft palate pharyngeal constrictors ( always a part of the pharynx) squeeze the pharynx laryngeal elevators raise the larynx and close off the airway. Anterior neck muscles control position of the larynx (control food/air separation, in elders, this is weakened) depress the mandible tense floor of mouth provide stable foundation for muscles of tongue and pharynx.
