The perineum is the diamond-shaped space between the pubic symphysis (anteriorly), the coccyx (posteriorly), and the ischial tuberosities (laterally), lying just inferior to the pelvic diaphragm (levator ani and coccygeus). : posterior neck muscles; includes the splenius capitis and splenius cervicis, splenius capitis The movements of the thumb play an integral role in most precise movements of the hand. The pelvic floor muscles support the pelvic organs, resist intra-abdominal pressure, and work as sphincters for the urethra, rectum, and vagina. The tendons are strong bands of dense, regular connective tissue that connect muscles to bones. The deep anterior compartment The flexor pollicis longus and the flexor digitorum profundus  produce flexion and bend fingers to make a fist. to access the musculoskeletal  reading review, Crash course video on muscles Muscles That Position the Pectoral Girdle, Similar to the muscles that position the pectoral girdle, muscles that cross the shoulder joint and move the humerus bone of the arm include both, . ). When you inhale, your chest rises because the cavity expands. This arrangement of three bands of muscles in different orientations allows various movements and rotations of the trunk. s  ulna bones The forearm, made of the : three transverse bands of collagen fibers that divide the rectus abdominis into segments, transversus abdomini The inferior surface is concave, creating the curved roof of the abdominal cavity. ). Muscles, Fascia, & … : muscles that span the spaces between the ribs, internal intercostal Because it is so moveable, the tongue facilitates complex speech patterns and sounds. The skeletal muscles are divided into : muscle that provides weak flexion of the hand at the wrist, pectoral girdle , The thenar muscles include the abductor pollicis brevis, opponens pollicis, flexor pollicis brevis, and the adductor pollicis. The muscles in the anterior compartment of the leg: the tibialis anterior, a long and thick muscle on the lateral surface of the tibia, the extensor hallucis longus, deep under it, and the extensor digitorum longus, lateral to it, all contribute to raising the front of the foot when they contract. The anterior muscles of the neck facilitate swallowing and speech. : muscle deep to the biceps brachii that provides power in flexing the forearm. . Those who have a muscle or joint injury will most likely be sent to a physical therapist (PT) after seeing their regular doctor. ) strong tendon that inserts into the calcaneal bone of the ankle, dorsal group ). The adductor longus flexes the thigh, whereas the adductor magnus extends it. , which is the prime mover of the eyebrows. , In medical terms, it is a joint between the proximal phalanx of either of the toes and the head of the adjacent bone of the foot. : circular muscle that moves the lips, palatoglossus For the purpose of this review, each of these systems will be discussed and explored separately. It controls flexion, lateral flexion, and rotation of the vertebral column, and maintains the lumbar curve.
