Muscle Anatomy Team Sports 1 Muscle Anatomy • Three types of muscles • 6 basic muscles • Ligaments vs. Tendons Types of Muscles Ligaments vs. Tendons • Skeletal/Voluntary- Skeletal muscle fibers occur in muscles which are attached to the skeleton. Those muscles that can be moved by our thoughts and actions. • Smooth/Involuntary MuscleMuscles that moves internal organs, such as the bowels, and vessels. Reflex action is made without our thought. • Cardiac- The muscle of the heart Ex: This muscle is constantly working automatically without thought or reflex being needed. Without this cardiac functioning muscle, we die! • Ligaments connect bones while tendons connect muscles to bones. Muscle Anatomy • Deltoids- a large, triangular muscle covering the joint of the shoulder, the action of which raises the arm away from the side of the body. • Basic Exercise: Shoulder press Muscle Anatomy • Latissimus Dorsi- a broad, flat muscle on each side of the mid-back, the action of which draws the arm backward and downward and rotates the front of the arm toward the body. • Basic exercise: lat pull down Muscle Anatomy • Hamstrings- any of the muscles/tendons that bound the bend of the knee. • Basic exercise: leg curls Muscle Anatomy • The masseter muscle is a facial muscle that plays a major role in the chewing of food. The muscle is shaped similar to a parallelogram, connecting to the mandible and the cheekbone. • Basic Exercise: jaw rotation, resistance type chewing motion http://www.healthline.com/human-body-maps/masseter-muscle: Dec. 2014: Copyright © 2005 - 2014 Healthline Networks, Inc. Muscle Anatomy • Anterior Cruciate Ligament- The ACL, is a primary stabilizing ligament within the center of the knee joint that prevents hyperextension and excessive rotation of the joint. Muscle Anatomy • Pronator Teres- a muscle that is primarily in the forearm and inserts into the radius. Pronates the hand and forearm (turns it hand palm up) • Basic exercise- dumbbell pronation, (any movement involving wrist rotation) Muscle Anatomy • Correctly label the six muscles/ligaments on the diagram provided. • Glue or tape into your notebook on the output side.
