Introduction to Muscles (02:09)
Learn about cardiac, smooth and skeletal muscle.
Skeletal Muscles (04:42)
Striated, voluntary muscles maintain posture by resisting gravity's pull, adjust themselves to stabilize joints, and generate heat. The seven naming criteria include location, shape, relative size, origin and insertion, direction of fibers, number of origins, and action; view examples.
Muscles of the Head (01:04)
Learn about the epicranius, orbicularis oculi, zygomaticus, risorius, orbicularis oris, and buccinator. Mastication muscles include masseter, temporalis and pterygoids. Intrinsic and extrinsic muscles control the tongue.
Anterior Neck and Throat Muscles (01:08)
Learn about the supra hyoid and infrahyoid muscles, pharyngeal constrictor, sternocleidomastoid, scalenes, splenius, semispinalis, and trapezius muscles. The erector spinae, semispinalis, and quadratus lumborum help move the trunk.
Muscles of the Thorax (01:16)
Deep thoracic muscles include external intercostals, internal intercostals, and the diaphragm. Superficial thoracic muscles include pectoralis major and minor, serratus anterior, subclavius, trapezius, rhomboids, and levator scapulae. Hear abdominal wall muscle functions.
Muscles of the Pectoral Girdle (00:41)
Muscles move the arm by directly acting on the humerus. These include the pectoralis major, latissimus dorsi, deltoid, teres major, teres minor, subcapularis, supraspinatus, and infraspinatus.
Muscles of the Limbs (00:56)
Learn about arm, superficial forearm muscles, and deep forearm muscles.
Muscles of the Hip and Leg (01:37)
Learn about hip, thigh, leg, and deep leg muscles, including quadriceps and hamstring.
Joints are sites where bones join together to make movement. Functional classifications include synarthroses, amphiarthrosis and diarthroses. Structural classifications include fibrous, cartilaginous and synovial joints. View examples of each.
Joint Problems (02:14)
Common injuries include sprains and dislocations. Arthritis refers to over 100 different kinds of inflammatory diseases; learn about osteoarthritis, rheumatoid and gout.
Muscles Review (01:38)
Review muscle types, skeletal muscle naming criteria, functional and structural joint types, and joint problems.
