What passes through medial bicipital groove?

What passes through medial 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.
…

What passes through intertubercular sulcus?

Fibrocartilage lines the intertubercular sulcus of the humerus and protects both the bone and the tendon of the long head of biceps brachii where the tendon passes through the sulcus. It provides a smooth, resilient, lubricated gliding surface on the bone.

What muscles go through bicipital groove?

Three muscle tendons insert on the bicipital groove region: lateral lip (crest of the greater tuberosity): pectoralis major. floor: latissimus dorsi. medial lip (crest of the lesser tuberosity): teres major.

Which muscle inserts into the greater tubercle and lateral lip of intertubercular sulcus of humerus?

The pectoralis major attaches to the lateral lip of the intertubercular sulcus.

What nerve passes through intertubercular groove?

Musculocutaneous nerve

The bicipital groove (intertubercular groove or sulcus) lies between the lateral edge of the lesser tuberosity medially and the greater tuberosity laterally. It is converted to a tunnel by the transverse humeral ligament, a thick band uniting the bony margins. . Musculocutaneous nerve (C5, 6 ).

Where is the intertubercular sulcus?

Description. The intertubercular groove (bicipital groove) is located between the greater and lesser tubercles on the cranioproximal part of the humerus. This groove is subdivided by a flat protuberance in ruminants and a prominent ridge in horses, called the intermediate tubercle.

Which head of the biceps brachii passes through the intertubercular groove?

After originating on the supraglenoid tubercle, the tendon of the biceps brachii muscle passes distally through the intertubercular groove of the humerus, where it is stabilized by the transverse humeral ligament. The muscle inserts distally on the radius and ulna, and its main function is flexion of the elbow.

How do you say intertubercular sulcus?

How To Say Intertubercular – YouTube

Is the bicipital groove the same as the intertubercular groove?

Anatomical Parts
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.

Where does the latissimus dorsi attach?

Through the thoracolumbar fascia latissimus dorsi attaches to the lumbar and sacral spinous processes (T6 to S5 levels), and the supraspinous ligament.

Which muscle inserts on the intertubercular sulcus of the humerus?

The lateral part forms the medial margin of the intertubercular sulcus. The subscapularis muscle attaches at this tubercle and the transverse ligament of the shoulder also attaches on its lateral part.

Which muscle inserts at the intertubercular sulcus of the humerus and is innervated by the lower Subscapular nerve?

Teres major muscle

What runs through the radial groove?

A broad, shallow groove that spirals down the posterior surface of the humerus and marks the route of the radial nerve and the deep brachial artery.

What do you mean by sulcus?

furrow, groove
-ˌsī : furrow, groove. especially : a shallow furrow on the surface of the brain separating adjacent convolutions.

What is mean by sulci?

Sulcus: A groove, furrow, or trench. The plural is sulci. In anatomy, there are many sulci; an example is the superior pulmonary sulcus.

Where is intertubercular sulcus located?

From a functional point of view, the most important region of the bicipital groove is the intertubercular sulcus, which is bounded by the lesser tuberosity medially, the greater tuberosity laterally, and the transverse humeral ligament superiorly (fig.

What tendon is located in the bicipital groove?

Bicipital groove (BG) is an indentation on the anterior aspect of proximal part of humerus. This groove allows tendon of long head of biceps brachi muscle enveloped in synovial sheath and ascending branch of anterior circumflex humeral artery to pass through it.

What are the attachments of the latissimus dorsi?

What is the origin and insertion of the latissimus dorsi?

Origin of the latissimus dorsi is from spinous processes of thoracic T7–T12, thoracolumbar fascia, iliac crest and inferior 3 or 4 ribs, inferior angle of scapula and insertion on floor of intertubercular groove of the humerus.

Where does the latissimus dorsi insertion?

Latissimus dorsi muscle

Which muscle inserts on the medial lip of the Intertubercular sulcus?

What nerve innervates the latissimus dorsi?

The thoracodorsal nerve
The thoracodorsal nerve is a pure motor nerve that innervates the latissimus dorsi muscle.

What is radial sulcus?

The radial groove (also known as the musculospiral groove, radial sulcus, or spiral groove) is a broad but shallow oblique depression for the radial nerve and deep brachial artery. It is located on the center of the lateral border of the humerus bone.

What muscles attach to the radial groove?

Radial nerve gives out muscular branches to supply the long head, medial head, and lateral head of triceps brachii muscles before and during its course in the radial sulcus. After it emerges out from the radial sulcus, it supplies the brachialis, brachioradialis and extensor carpi radialis longus.
