Dissection Theory of Upperlimb

In this eLearning module, you will learn about Cubital Fossa and anastomosis around the elbow joint. The cubital fossa is a small triangular area located on the anterior surface of the elbow, with the apex of the triangle pointing distally. It is bordered by two forearm muscles, brachioradialis laterally and pronator teres medially. Anastomosis at the level of the elbow joint connects the deep, or normal, brachial artery with major arterial variations of the upper limb.

In this eLearning module, you will learn about Muscles of Anterior Compartment of Forearm. The muscles in the anterior compartment of the forearm are organised into three layers, superficial, intermediate, deep. The forearm is the portion of the arm distal to the elbow and proximal to the wrist. This muscle group is associated with pronation of the forearm, flexion of the wrist and flexion of the fingers.

In this eLearning module, you will learn about Axilla - II Axillary artery and axillary vein. The axillary artery is a blood vessel that provides the axilla, the lateral portion of the thorax, and the upper limb with oxygenated blood. The axilla is the name given to an area that lies underneath the glenohumeral joint, at the junction of the upper limb and the thorax. The axillary artery is a large muscular vessel that travels through the axilla.

In this eLearning module, you will learn about Spaces of Scapula & Scapular Anastomoses. The scapular region is on the superior posterior surface of the trunk and is defined by the muscles that attach to the scapulaThe pectoral girdle has a rich plexus of arterial vessels that anastomose around the scapula and its muscles known as the scapular anastomosis.

In this eLearning module, you will learn about Muscles of Hand. The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. These muscles can be subdivided into two groups, extrinsic and intrinsic. The extrinsic muscles are located in the anterior and posterior compartments of the forearm. They control crude movements and produce a forceful grip. The intrinsic muscles are those muscles that are responsible for the fine motor functions of the hand.

In this eLearning module, you will learn about Flexor Retinaculum. Flexor retinaculum is a strong fibrous band which bridges the anterior concavity of the carpal bones thus converts it into a tunnel, the carpal tunnel. The flexor retinaculum protects nine of the forearm flexor tendons and median nerve as they pass through the carpal tunnel. The ulna aspect of the flexor retinaculum forms the floor of Guyon"s canal.

In this eLearning module, you will learn about Introduction to Upperlimb. The upper limb is associated with the lateral aspect of the lower portion of the neck. It is suspended from the trunk by muscles and a small skeletal articulation between the clavicle and the sternum, the sternoclavicular joint. It consists of three sections, the upper arm, forearm, and hand. It also consists of many nerves, blood vessels (arteries and veins), and muscles. There are 4 main groups of bones in the upper limb, the bones of the shoulder girdle, upper arm, forearm, and the bones of the hand.

In this eLearning module, you will learn about Spaces in the hand/ Fascial spaces in the palm. Spaces of hand are formed by fascia and fascial septae. Fascia and fascial septae of the hand are arranged in such a manner that many spaces are formed. The important spaces on the palmar aspect are midpalmar space, thenar space, pulp spaces of the fingers.

In this eLearning module, you will learn about Extensor Retinaculum. Extensor Retinaculum is a fibrous, thickened band that holds the extensor tendons at the dorsum of the wrist. Extensor Retinaculum helps to keep the extensor tendons in alignment and prevent bowstringing during movements. By extending fascial attachments to the underlying bones and periosteum, the retinaculum forms six osseofascial compartments over the dorsal wrist.

In this eLearning module, you will learn about Pectoral Region & mammary gland. The breast and pectoral region is on the anterior and superior part of the thorax. Structural support for the pectoral muscles and the mammary glands is primarily provided by the upper eight ribs along with their attachment to the lateral part of the sternum by way of costal cartilages. The mammary gland is a gland located in the breasts of females that is responsible for lactation, or the production of milk.

In this eLearning module, you will learn about Vessels & nerves of anterior compartment of forearm. The forearm is the region of the body spanning from the elbow to the wrist. The muscles in the anterior compartment of the forearm are organised into three layers, superficial, intermediate, deep. Cutaneous nerve supply of the forearm.

In this eLearning module, you will learn about Vessels & nerves of arm. The arteries that supply the arm is the brachial artery and its four branches, profunda brachii artery, nutrient artery to humerus, superior ulnar collateral artery, inferior ulnar collateral artery. Through the four branches the brachial artery supplies the content of the arm. The nerves of the upper limb include the musculocutaneous, axillary, median, radial and ulnar nerves.

In this eLearning module, you will learn about Muscles of Arm. The upper arm is located between the shoulder joint and elbow joint. It contains four muscles in which 3 are located in the anterior compartment; biceps brachii, brachialis, coracobrachialis, and one in the posterior compartment; triceps brachii.

In this eLearning module, you will learn about Vessels and Nerves of Posterior Compartment of forearm. The forearm is divided into the posterior compartment and the anterior compartment by the deep fascia, lateral intermuscular septum and the interosseous membrane between the ulna and radius. The arterial supply is carried out by anterior and posterior interosseous arteries, which are branches of the short common interosseous artery, arise from the proximal ulnar artery. All muscles in the extensor compartment are supplied by the radial nerve.

In this eLearning module, you will learn about Axilla - I Introduction And Content of axilla. In this eLearning module, you will learn aboutThe axilla is an anatomical region under the shoulder joint where the arm connects to the shoulder. The axilla allows the passage of several muscles, blood vessels such as the axillary artery and vein, and crucial nerves like the brachial plexus. The floor of the axilla is tough axillary fascia that connects the thoracic wall, the gleno-humeral joint, and the posterior part of the axilla.

In this eLearning module, you will learn about Brachial Plexus, The Brachial Plexus is the network of nerves that sends signals from your spinal cord to your shoulder, arm and hand. It is formed from the ventral rami of the 5th to 8th cervical nerves and the ascending part of the ventral ramus of the 1st thoracic nerve. The brachial plexus passes from the neck to the axilla and supplies the upper limb.

In this eLearning module, you will learn about the Vessels & Nerves of Hand. Human hands are supplied by an intricate network of blood vessels & nerves. The hand’s blood supply comes entirely from 2 main sources: the ulnar & radial arteries. Both originate from the brachial artery. The ulnar artery travels down the medial forearm & enters the hand medially, while the radial artery runs down the lateral forearm & enters the hand laterally.

In this eLearning module, you will learn about the Muscles of Scapular Region. The scapula or shoulder blade is the bone that connects the clavicle to the humerus. Muscles of the scapula include the rotator cuff muscles, teres major, subscapularis, teres minor & infraspinatus. These muscles attach to the scapular surface & assist with abduction and external and internal rotation of the glenohumeral joint.
