Tendons and Ligaments
Tendons and ligaments Tendons A fibrous connective tissue that attaches muscle to bone. Tough yet flexible Tendons purpose is to move the bone Ligaments A fibrous connective tissue that attaches bone to bone Serves to hold structures together and keep them stable – particularly at the joint Slightly elastic so they can be stretched and gradually lengthen, increasing flexibility

Origin vs. Insertion Origin Immovable point of attachment of a muscle to a bone. Does not change its shape when the muscle moves A muscle contracts toward it Typically higher on the bone Insertion Muscle attachment to a moveable bone. Does not change its shape when the muscle moves Has the greatest motion when the muscle contracts Typically lower on the bone

Pectoralis Major Location : Chest Muscle Function : Moves the shoulder and arm towards the chest Pushes Origin : Sternum and Second through Sixth Rib Insertion : Clavicle and the Humerus
Latissimus Dorsi Location : Down spine, across the back armpit Function : Pulls arm toward back Origin : Thoracic/Lumbar Vertebrae, Sacrum, Pelvis, and four most inferior ribs Insertion : Back of Humerus
Gluteus Maximus Location : Buttocks Function : Straightens the leg at the hip Origin : Pelvis, Sacrum and Coccyx Insertion : Femur
Abdominals Location : Stomach area Function : Flexes the trunk (sit-up) Origin : Thoracic Diaphragm Insertion : Pelvis and between the lumbar vertebrae and sacrum
Hamstrings Location : Back of thigh Function : Bends the knee and strengthens leg at hip Origin : Underneath the gluteus maximus and the pelvic bone Insertion : Tibia
Quadriceps Location : Front of thigh Function : Straightens the knee, raises the leg at the hip Origin : Femur/pelvis Insertion : Patella
Sartorius Location : Outer thigh at hip, across the thigh to the inside of the lower leg at the top of the knee Function : Rotates the thigh Origin : Pelvis Insertion : Inside of the tibia ** Longest muscle
Gastrocnemius Location : Calf muscle, Back of lower leg Function : Raises you up on your toes Origin : Femur Insertion : Achilles tendon to the heel
Anterior Tibialis Location : Front of the lower leg Function : Pulls foot up towards lower leg Origin : Tibia Insertion : Foot
Sternocleidomastoid Location : Neck Function : Turns the head side to side Origin : Inside part of the clavicle Insertion : Temporal bone (cranium)
