Document Summary

5 muscles and nerves of the head, neck, and trunk. Muscle: name the different types of muscular tissue, explain how a muscle produces movement, explain the nomenclature of the skeletal muscle. Muscle classification: skeletal voluntary control, striated, cardiac involuntary control, striated, only found in heart, smooth involuntary control, nonstriated, smooth. If you know the origin and insertion of a muscle, you can often point out the function; pulling on a string from insertion to the origin: origin, usually proximal usually remains fixed during contraction. Insertion: usually distal usually moves towards the origin. Function extensor, digitorum, erector spinae: attachment to the sternum, clavicle, and mastoid process. Muscles of the head: categorize the muscles of the head and explain their characteristics including, origin, insertion, innervation, function. Tongue muscles change shape and location of tongue to assist in mastication, swallowing, and speech. 5 branches of facial nerves come out in front of ear and split into different directions.
