To remember which is which remember supination has up in it.

Anatomy of the forearm. Vascular Anatomy of the Upper Arm. The forearm consists of two long bones. The muscle splits into four tendons at the wrist which travel through the carpal tunnel and attaches to the middle phalanges of the four fingers.

Triceps brachii is innervated by the radial nerve C6-C8 and receives its blood supply from the deep brachial and superior ulnar collateral arteries. The forearm is the region of the upper limb between the elbow and the wrist. The muscle is a good anatomical landmark in the forearm the median nerve and ulnar artery pass between its two heads and then travel posteriorly.

Vascular Anatomy of the Forearm. The back compartment of the forearm includes 12 muscles that are largely involved in the movements of extension or straightening of the wrist and fingers and the palm-up rotation of the arm. Flexion of the forearm is achieved by a group of three muscles the brachialis biceps brachii and brachioradialis.

Anatomy - Back of forearm 1. The radius and the ulna. These forearm bones articulate with each other in two locations.

It articulates with the scapula Fig. Body Part Organ or Organ Component T023 MSH. The anatomy of the arm consists of only three bones but a number of muscles tendons and nerves.

At the elbow bending is flexion straightening is extension. They include four superficial two intermediate and six deep muscles. Overall the forearm comprises the lower half of the arm.

Right the fibula and the tibia bones of the lower leg. The muscles that extend the hand at the wrist are located on the posterior portion of the forearm. 131 at the glenohumeral joint proximally and the radius and the ulna distally at the elbow joint.

The radius and ulna bones of the forearm shown in supination the arm rotated outward so that the palm of the hand faces forward. Additionally due to its attachment on the scapula it can also act as a weak extensor and adductor of the arm at the shoulder joint. The forearm contains more muscles than the upper arm does.

The term forearm is used in anatomy to distinguish it from the arm a word which is most often used to describe the entire appendage of the upper limb but which in anatomy technically means only the region of the upper arm whereas the lower arm is called the forearm. However its compartmental anatomy has not been widely reviewed in the radiology literature. Forearm C0016536 Definition NCI The structure on the upper limb between the elbow and the wrist.

13 The Anatomy of the Arm 131 Humerus The humerus is the largest bone in the upper limb. Left The radius and the ulna bones of the forearm. Rotation of the forearm is referred to as pronation and supination.

Deep Muscle group 2. The ulna is located medially and is both longer and larger than the radius which runs parallel to it laterally. These two bones are held together by the intervening interosseous membrane.

All three heads join to form a single tendon which inserts onto the olecranon of ulna and fascia of the forearm. Vascular Anatomy of the Spine. - Elbow consists of 3 articulations.

Ulnohumeral elbow flexionextension Radiohumeral forearm pronationsupination Radioulnar forearm pronationsupination Elbow Joint Articulation 6. These flexor muscles are all located on the anterior side of the upper arm and extend from the humerus and scapula to the ulna and radius of the forearm. There are two groups of muscles at the back of forearm.

It is homologous to the region of the leg. The ulnar median and radial nerves are the major nerves of the forearm. Superficial Muscle group 2.

Definition NCI_CDISC The structure on the upper limb between the elbow and the wrist. Division of the forearm into the mobile wad volar and dorsal compartments provides a convenient and practical way to review its important muscles nerves and vessels. Extensor digiti minimi 7.

It has two heads one originates from the medial epicondyle of the humerus the other from the radius. Triceps brachii is the prime extensor of the forearm at the elbow joint. These two long bones form a rotational joint.

There are seven muscles in the superficial group. Extensor carpi radialis longus 4. Pronation puts the palm of the hand down and supination brings it up.

At the end of the forearm are the metacarpal bones which make up the wrist joint and attach the hand to the arm. The anatomy of the forearm is depicted in several excellent atlases. The tendons of the hand extensor muscles pass under the extensor retinaculum and attach to the.

It extends from the elbow joint to the hand and it is made up of the ulna and radius bones.
