Muscles of the Upper Arm There are three muscles located in the anterior compartment of the upper arm – biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve. A good memory aid for this is BBC – biceps, brachialis, coracobrachialis.

Arm The human arm is a complex system of bones, muscles, nerves, and vessels.he arm consists of several segments that together make it one of the most useful and complex tools of the human body. These parts are: 1  Upper arm: Extending from the shoulder to the elbow, the upper arm provides pulling and lifting strength.

Muscles of the Elbow An additional nine muscles cross the elbow to act upon on the wrist and joints of the hand. These muscles can be broadly grouped into the flexor and extensor groups of the forearm. The flexor group - including the brachialis, biceps brachii, and the brachioradialis - bend the arm by decreasing the angle between the forearm and upper arm.

Trabe In 2372, attempts by Captain Kathryn Janeway of the Federation starship USS Voyager to form an alliance with one or more Kazon sects led to her forming such an alliance with the Trabe instead. The Trabe leader, Mabus, proposed a bolder plan, one that would bring peace between Voyager, the Trabe, and the Kazon.

- The shoulder forms a base for the arm with most of the upper arm muscles originating from this area. In the upper arm, the biceps and triceps are arranged to give the forearm power to thrust and bend. The two muscles join at the elbow and allow you to bend and straighten your arm and also rotate your wrist and hand.The forearm muscles transmit power to the wrist, hands, and fingers.he biceps brachii (two-headed arm muscle) consists of the long head and the short head. It extends from the shoulder to the elbow and is the main flexor of the elbow joint. When working with other nearby muscles, it can also move the shoulder, since its upper ends are attached to the scapula (shoulder blade).

Arm In human anatomy, the arm is the upper limb of the body, comprising regions between the glenohumeral joint (shoulder joint) and the elbow joint. In common usage the arm extends to the hand. It can be divided into the upper arm (brachium), the forearm (ante brachium), and the hand (manus).Anatomically the shoulder girdle with bones and corresponding muscles is by definition a part of the arm. The Latin term brachium may refer to both the arm as a whole or to the upper arm on its own.n human anatomy, the arm is the upper limb of the body, comprising regions between the glenohumeral joint (shoulder joint) and the elbow joint.

Anatomy Your arm is kept in your shoulder socket by your rotator cuff. The rotator cuff is a network of four muscles that come together as tendons to form a covering around the head of the humerus. The rotator cuff attaches the humerus to the shoulder blade and helps to lift and rotate your arm.

Bones of the Arm and Hand Many muscles attach to the scapula to move the shoulder, including the trapezius, deltoid, rhomboids, and the muscles of the rotator cuff. The humerus is the only bone of the upper arm. It is a long, large bone that extends from the scapula of the shoulder to the ulna and radius of the lower arm. The proximal end of the humerus, known as the head, is a round structure that forms the ball of the ball-and-socket shoulder joint.

Anatomy Your shoulder is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle). The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid.A combination of muscles and tendons keeps your arm bone centered in your shoulder socket. These tissues are called the rotator cuff. They cover the head of your upper arm bone and attach it to your shoulder blade.hat most people call the shoulder is really several joints that combine with tendons and muscles to allow a wide range of motion in the arm — from scratching your back to throwing the perfect pitch. Mobility has its price, however.

Biceps For other uses, see Biceps (disambiguation). In human anatomy, the biceps brachii (/ˈbaɪsɛps ˈbreɪki.aɪ/), commonly known as the biceps, is a two-headed muscle that lies on the upper arm between the shoulder and the elbow. Both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.

The Rotator Cuff - S.I.T.S Muscles The Four Rotator Cuff Muscles: The four muscles that form the rotator cuff are the supraspinatus, infraspinatus, teres minor, and subscapularis. Often the mnemonic S.I.T.S is used to help remember the muscles that make up the rotator cuff. Supraspinatus: The supraspinatus muscle originates above the spine of the scapula and inserts on the greater tuberosity of the humerus. The supraspinatus abducts, or elevates, the shoulder joint out to the side.

Muscles It is controlled by two muscles, the biceps on the front of the upper arm, and the triceps on the back of the upper arm. The biceps and the triceps are antagonistic muscles. when the biceps muscle contracts, the forearm moves up. when the triceps muscle contracts, the forearm moves down. This solves the problem. To lift the forearm, the biceps contracts and the triceps relaxes.

What Are the Names of the Muscles in the Arm & Shoulder? The pectoralis muscles -- major and minor -- attach your ribs to the front of your upper arm. These muscles lift your arm forward, bring it in toward your body and rotate your shoulder inward. The coracobrachialis is a deep muscle on the front of your upper arm that moves your arm forward.
