The bicipital aponeurosis originates from the distal insertion of the biceps brachii, and inserts into the deep fascia of the forearm. [1] The biceps tendon inserts on the radial tuberosity, and the bicipital aponeurosis lies medially to it. [2] It reinforces the cubital fossa, helping to protect the brachial artery and the median nerve running ...
The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm") is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Both heads of the muscle arise on the scapula and join to form a single muscle belly which is attached to the upper forearm.
The anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment. The compartment contains three muscles; the biceps brachii, the brachialis and the ...
The mid-upper arm fat area (MUAFA) is an estimation of the area of the far portions of the upper arm, and is simply the difference between the MUAA and the MUAMA: [6] = [6] From the MUAFA is derived the arm fat index (AFI), a percentage of the arm that is fat, using the following formula: [6]
[1] [2] When the forearm is pronated, the brachioradialis tends to supinate as it flexes. [2] In a supinated position, it tends to pronate as it flexes. [2] This also assists the biceps brachii. [2] The brachioradialis is a stronger elbow flexor when the forearm is in a midposition between supination and pronation at the radioulnar joint. When ...
Forearm flexors: The muscles on the pinky side of your lower arm help grab and grip. Thenar muscles: The muscles that help your thumb pinch toward your fingers.
The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow. It lies beneath the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit). It originates from the anterior aspect of the distal humerus; [1] it inserts onto the tuberosity of the ulna.
The bicipitoradial bursa is a bursa located between the distal tendon of the biceps brachii muscle and the anterior part of the tuberosity of the radius. [1] It partially or completely wraps around the biceps tendon. It ensures frictionless motion between the biceps tendon and the proximal radius during pronation and supination of the forearm ...
