Biceps Brachii - It's attachments are the coracoid process, supraglenoid tuberosity, and radial tuberosity. When it contracts it causes flexion and supination. It's located close to the endangerment site the antecubital. This area is known for housing chronic pain.

Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example, originates at the chin (geneion) and inserts in the tongue (glossus). Some muscles are named for the arrangement of the fascicle groups. For example the rectus abdominus is the straight muscle that is in the adbominus.

The biceps femoris is one of the three muscles including the semitendinosus, and the semimembranosus, that make up the group of muscles called the hamstrings. The hamstrings are located on the posterior side of the leg. The biceps femoris originates on the ischial tuberosity and inserts on the head of the fibula. The movement of the biceps femoris is responsible for the flexion of the knee and the external rotation of the lower leg. Flexion of the knee happens when the back of the foot is raised toward the back of the leg.

In the text of Lippert she explains that there are many muscles in the body, but were focusing on just the muscles involved with the elbow. “The brachialis muscles, it has two heads and is located on the arm also knows as just the biceps and its actions are to flex the elbow” 3 (p. 152) “The

There are about 600 muscles in the body working together to create movement. Muscle contractions pull both ends of the muscle towards one another. One bone attached to each muscle is always more stabilized than the other. The less stabilized bone moves during muscle contraction due to the weaker stability. The points of attachment determine which bone will move. The least movable part is called the origin; it is the part that attaches closer to the midline of the body. This leaves the most movable part called the insertion. Each of these points can be identified in individual muscles to assist trainers in understanding how the muscles and joints work together to create motion.

The shoulder helps you to have full range of movement of your arm so that you can move your arm in a complete circle. Different bones and muscles make up the shoulder. There is the scapula, or the shoulder bone, this is the flat triangular bone that you feel in your back. Extending over the front of the shoulder and over is the clavicle, or collar bone, which is attached to the scapula and sternum, helping to stabilize the movement of the shoulder. The humerus is the longest bone in the arm and is connected to the scapula and clavicle.

There are the Smooth, the Skeletal, and the Cardiac muscular tissues. Smooth muscles are made of spindle-shaped cells.

Muscles work in groups. Reciprocal inhibition is the arrangement and use of opposite pairs of muscles, that is when one muscle contracts the opposing muscle lengthens and vice versa. For example, the muscles responsible for movement of the lower arm at the elbow are the biceps brachii muscle and the triceps brachii muscle. In order to raise the upper arm the biceps brachii is the prime mover. When this muscle is stimulated and therefore shortens, the nerve impulse to the opposite muscle (triceps brachii, the antagonist) is inhibited.

semitendinosus muscle, figure 1, the muscles extending - except the short head of the biceps - ie between two joints of the hip and knee.

Several muscles of the upper and lower arm attach at the elbow on the olecranon process. In the posterior compartment of the upper arm, the three heads of the triceps brachii converge into a single tendon that connects

Triceps brachii: This muscle at the back of the upper arm extends the arm and fixes the elbow when the hand is used for fine movements.

Other than bones, this system is also a network of tendons, ligaments and cartilage that connects them. Tendons play an important role as they connect a muscle to the bone. This whole process comes under The muscular system which consists of skeletal, smooth and cardiac muscles. Skeletal muscles are voluntary and attach to bones by tendons and other tissue. Cardiac muscles are involuntary muscles around the heart whereas smooth muscles surround organs of the

Skeletal muscles consist of numerous elongated cells called muscle fibres; these fibres are arranged in bundles called fasciculi. Each muscle is composed of hundreds of muscle fibres enclosed within a protective tissue envelope; most of these fibres extend the full length of the muscle. The fibres within each fasciculus are separated

Some skeletal muscles in face are directly attached to skin this helps in facial expression. Contraction helps in pulling the tendons on the bones that causes movement such as extension of arm, breathing, cycling, typing and writing. In breathing not only it helps for inhale and exhale but also laugh, sneeze and cough. Generate heat as a byproduct of muscle activity. It maintains of posture. The gluteal
