Information about Intertubercular Groove

The humerus is a long bone in the arm or fore-legs (animals) that runs from the shoulder to the elbow. On a skeleton, it fits between the scapula and the ulna. It consists of the following three sections:

• Upper extremity of humerus
• Body of humerus

In human anatomy, the biceps brachii is a muscle located on the upper arm. The biceps has several functions, the most important simply being to flex the elbow and to rotate the forearm.

The anterior humeral circumflex artery (anterior circumflex artery, anterior circumflex humeral artery), considerably smaller than the posterior, arises nearly opposite it, from the lateral side of the axillary artery.

In human anatomy, the shoulder comprises the part of the body where the arm attaches to the torso. It is made up of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone) as well as associated muscles, ligaments and tendons.

The radial sulcus is a groove for the radial nerve on the humerus bone.

The center of the lateral border of the humerus is traversed by a broad but shallow oblique depression, the radial sulcus (musculospiral groove, radial groove, spiral groove).

Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals.

In human anatomy, the upper limb (also upper extremity) refers to what in common English is known as the arm, that is, the region of the shoulder to the fingertips. It includes the entire limb, and thus, is not synonymous with the term upper arm.

The pectoral girdle is the set of bones which connect the upper limb to the axial skeleton on each side. It consists of the clavicle and scapula in humans and, in those species with three bones in the pectoral girdle, the coracoid. Some mammalian species (e.g.

scapula, or shoulder blade, is the bone that connects the humerus (arm bone) with the clavicle (collar bone).

The scapula forms the posterior part of the shoulder girdle. In humans, it is a flat bone, roughly triangular in shape.

The spine of the scapula is a prominent plate of bone, which crosses obliquely the medial four-fifths of the dorsal surface of the scapula at its upper part, and separates the supra- from the infraspinatous fossa.

The suprascapular notch (or scapular notch) is a notch in the lateral part of the upper border of the scapula, just next to the base of the coracoid process.

The acromion process, or simply the acromion, is an anatomical feature on the scapula.

In humans

It is a continuation of the scapular spine, and hooks over anteriorly.

The acromion articulates with the clavicle to form the acromioclavicular joint.

The coracoid process is a small hook-like structure that comes off the scapula to point forward.

Attachments

It is the site of attachment for several structures:

• The pectoralis minor muscle - to 3rd to 5th ribs.

The costal or ventral surface of the scapula presents a broad concavity, the subscapular fossa.

It provides an attachment for the subscapularis muscle.
