What is intermuscular septa of arm?

The lateral intermuscular septum separates the anterior and posterior compartments of the arm and extends from the crest of the greater tuberosity of the humerus to the lateral epicondyle where it becomes confluent with the annular ligament encircling the radial head [10].

Where is the intermuscular septum?

The medial intermuscular septum, thicker than the preceding, extends from the lower part of the crest of the lesser tubercle of the humerus below the Teres major, along the medial supracondylar ridge to the medial epicondyle; it is blended with the tendon of the Coracobrachialis, and affords attachment to the Triceps …

Is Septa an intermuscular fascia?

The deep transverse fascia or transverse intermuscular septum of leg is a transversely placed, intermuscular septum, from the deep fascia, between the superficial and deep muscles of the back of the leg. At the sides it is connected to the margins of the tibia and fibula.

What is the medial intermuscular septum?

Anatomical terminology The medial intermuscular septum of thigh is a fold of deep fascia in the thigh. It is between the vastus medialis, and the adductors and pectineus. It separates the anterior compartment of the thigh from the medial compartment of the thigh.

What is Intermuscular?

n. Any of the aponeurotic sheets separating various muscles of the extremities, including the anterior and posterior crural septa, the lateral and medial femoral septa, and the lateral and medial humeral septa.

What is anterior forearm?

The superficial anterior forearm muscles are a group of five muscles located in the anterior (flexor) compartment of the forearm. These muscles include the pronator teres, flexor carpi radialis, flexor carpi ulnaris, palmaris longus and flexor digitorum superficialis.

What is intermuscular septa of leg?

Anatomical terminology The anterior intermuscular septum of leg or anterior crural intermuscular septum is a band of fascia which separates the lateral from the anterior compartment of leg.

What is the intermuscular septa made of?

Fibrous connective-tissue sheets that partition muscle groups in the limbs. Both muscles arise from the adjacent anterior and posterior intermuscular septa.

How many fascial compartments are in the forearm?

The forearm is the region of the body spanning from the elbow to the wrist. It consists of several muscles and an extensive neurovascular network encased in three compartments. These include the anterior compartment, posterior compartment, and the mobile wad.

How are forearm compartments formed?

The upper limb is divided into two segments, the arm and the forearm. Each of these segments is further divided into two compartments which are formed by deep fascia – tough connective tissue septa (walls). Each compartment encloses specific muscles and nerves.

What is intermuscular septum of leg?

The anterior intermuscular septum of leg or anterior crural intermuscular septum is a band of fascia which separates the lateral from the anterior compartment of leg.

What is the function of intermuscular septa?

1. A connective tissue septum that separates two muscles, esp. one from which muscles may take their origin.

What does the intermuscular septa do?

The Intermuscular Septa The deep fascia of the arm completely encircles it, like a tube. It is continuous above with the fascia covering the deltoid, pectoralis major and teres major muscles, and axillary fascia. Below, it is continuous with the fascia of the forearm and is attached to the olecranon and internal and external condyles.

What is the intermuscular septum of the elbow?

These intermuscular septa are of importance in operative procedures because they indicate the limits of the muscles and position of nerves and vessels. Inasmuch as the movements of the elbow-joint are anteroposterior only and not lateral, the muscles are principally on the front and back and not on the sides.

What are the two compartments of the forearm?

Just like the arm, the forearm is divided into two compartments by deep fascia; the interosseous membrane, and the fibrous intermuscular septa. This creates an anterior compartment that contains the flexor muscles, and a posterior one that contains the extensor muscles.

What are the internal and external septa of the humerus?

On each side of the lower half of the humerus, extending from the condyles and the bone above outward to the deep fascia, are two fibrous partitions. They are the internal and external intermuscular septa. The space in front of them is filled by the flexors, the biceps, and brachialis anticus, and the space behind contains the triceps extensor.
