HPE 365 Study Guide - Midterm Guide: Subscapularis Muscle, Latissimus Dorsi Muscle, Pectoralis Major Muscle
Document Summary
Biomechanics exam 1 study guide. Joint capsule surrounds the bony ends forming the joints. Joint cavity area inside the joint capsule. Ligaments connect bone to bone. Hyaline cartilage covers articular surfaces on ends of bones inside joint cavity. Dorsal & plantar flexion. Horizontal flexion & extension. Kinesiology the study of human movement. Structural kinesiology the study of muscles, bones & joints involved in the science of movement. Biomechanics the physics (mechanics) of motion exhibited or produced by biological systems. Muscles: 600+ muscles, 215 pairs of skeletal muscles work in cooperation with each other. Roles of muscles: transverse/horizontal. Concentric shorting of the muscle (causing motion) Eccentric lengthening of the muscle (controlling motion) Hamstring muscles: rectus femoris, vastus intermedius (sits under the rectus femoris, vastus lateralis, vastus medialis. They all insert on the tibial tuberosity. All do extension except the rectus femoris also does flexion of the hip & anterior pelvic rotation: semitendinosus, semimembranosus, biceps femoris.
