 sarcomere- basic contractile unit of muscle fibers. Contains two protien filaments - actin and myosin. - contractile fibers the that surround circular-ring-shape like a doughnut , such as muscles the mouth , Pupils and the anus. Convergent - Fan shaped or triangular , attach to a fixed bone. They have fascicles spread wide together that over a area and come at a single joint major muscle flexes the upper arm /Chest , Pectoralis major Parallel-musclesInclude : Rectus abdominis , biceps branchii , Sternocleidomastoid. Long muscles made up of fibers that run parallel to each other. When they contract , they Shorten in length and increase diameter , allows movement lower leg back leg Side digitorum longus - unipennate - Extensor , Flexor hallucis longus , Gluteus maximus , lateral gastrocnemius. Muscle fibers are all on one side of the tendon. Shoulder multipennate-deltoiduscle. Have fascicles that Insert on multiple tendons tapering towards a common tendon. of arm anterior fusiform-biceps branchii , Palmaris longus. Greater range of motion and joint velocity. quads - middle ear Bipennate-Rectus femoris , Stapedius. muscles that have fibers on two sides of the tendon  * muscles make the rotater cuff : Supraspinatus up , infraspinatus , teres minor , subscapularis. Lateral and medial views of the extrinsic eye muscles Direction of eye movement produced by extrinsic eye muscles Levator palpebrae Levator palpebrae superioris superioris Superior Trochlea Trochlea (ligamentous sling) Optic rectus Superior oblique Frontal bone Trochlea nerve Optic Ex t r i n s i c Eye nerve Muscles Superior oblique Superior rectus Lateral rectus Lateral Medial rectus Medial rectus rectus Inferior oblique Inferior Inferior rectus oblique Maxilla Inferior rectus © 2018 Pearson Education, Inc.
