What is a bicipital groove?
The bicipital groove is an indentation that lies along the anterior aspect of the proximal humerus and contains the tendon of the long head of the biceps brachii muscle (fig. 1 ).
What is bicipital groove in medical terms?
Medical Definition of bicipital groove : a furrow on the upper part of the humerus occupied by the long head of the biceps.
What is the bicipital groove formed by?
The medial bicipital groove is seen on the surface anatomy of the upper arm. It is formed by the longitudinal hollow between the biceps and triceps muscles. The pulse of the brachial artery can be felt in the medial bicipital groove.
Where do I find the bicipital groove?
Place your index finger on one tubercle and the ring finger of the same hand on the other tubercle. The middle finger of the same hand is placed in between the other two fingers to palpate the area of the biciptal groove. The tendon of the long head of the biceps brachii is located in this groove.
Why is it called the bicipital groove?
The bicipital groove (intertubercular groove, sulcus intertubercularis) is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle. It allows for the long tendon of the biceps brachii muscle to pass….

- lateral lip (crest of the greater tuberosity): pectoralis major.
- floor: latissimus dorsi.

What does aponeurosis mean in anatomy?
aponeurosis, a flat sheet or ribbon of tendonlike material that anchors a muscle or connects it with the part that the muscle moves. The aponeurosis is composed of dense fibrous connective tissue containing fibroblasts (collagen-secreting spindle-shaped cells) and bundles of collagenous fibres in ordered arrays.
Which is the bicep?
The biceps is a muscle on the front part of the upper arm. The tendons that connect the biceps muscle to the shoulder joint in two places are called the proximal biceps tendons. The tendon that attaches the biceps muscle to the forearm bones (radius and ulna) is called the distal biceps tendon.
What nerve passes through the bicipital groove?
The greater and lesser tubercles of humerus are separated from each other by a deep groove, the intertubercular groove (bicipital groove), which lodges the long tendon of the Biceps brachii and transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.
What is the Bicipital Aponeurosis?
Bicipital aponeurosis or lacertus fibrosus is an aponeurosis from the tendon of biceps brachii muscle in the cubital fossa. The bicipital aponeurosis is presumed to protect the neurovascular bundle in the cubital fossa such as median nerve and the brachial artery, which pass deep to it [1].
What is the meaning of the bicipital groove?
bicipital groove [bīsip′ətəl] a groove between the greater and lesser tubercles of the humerus for passage of the tendon of the long head of the biceps muscle.
What kind of tendon is in the bicipital groove?
The bicipital groove is typically 4-6 mm deep 1 . It contains the tendon of the long head of the biceps brachii muscle, which is ensheathed in a synovial reflection of the glenohumeral joint. Three muscle tendons insert on the bicipital groove region:
Where is the bicipital groove on the humerus?
A valley on the proximal anterior surface of the humerus between the greater and lesser trochanters. The long tendon of the biceps slides along the bicipital groove. Want to thank TFD for its existence?
What can bicipital groove morphometry be used for?
The variant morphometry of bicipital groove is reported to be associated with pathologies of biceps tendon and is useful in surgical procedures in this region. The pathologies of biceps tendon are frequent causes of shoulder pain.
