Of the three borders of the scapula, the superior border (or superior margin) is the shortest and thinnest; it is concave, and extends from the medial angle to the base of the coracoid process. ...

Structure It arises from the upper border of the scapula, and occasionally from the superior transverse scapular ligament which crosses the scapular notch, its extent of attachment to the scapula varying from a few millimetres to 2.5 cm. Left scapula - front view () Left scapula - rear view () In anatomy, the scapula, or shoulder blade, is the bone that connects the humerus (arm bone) with the clavicle (collar bone). ...
The superior transverse ligament (transverse or suprascapular ligament) converts the scapular notch into a foramen. ...
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. ...
From this origin, the inferior belly forms a flat, narrow fasciculus, which inclines forward and slightly upward across the lower part of the neck, being bound down to the clavicle by a fibrous expansion; it then passes behind the Sternocleidomastoideus, becomes tendinous and changes its direction, forming an obtuse angle. Fasciculus can refer to: Arcuate fasciculus Dorsal longitudinal fasciculus Medial longitudinal fasciculus Flechsigs fasciculus Fasciculus Chemicus A structure in the Wrist#Volar_radiocarpal_ligament Category: ...
In human anatomy, the sternocleidomastoid muscles are muscles in the neck that act to flex and rotate the head. ...
It ends in the superior belly, which passes almost vertically upward, close to the lateral border of the Sternohyoideus, to be inserted into the lower border of the body of the hyoid bone, lateral to the insertion of the Sternohyoideus. The Sternohyoideus (Sternohyoid muscle) is a thin, narrow muscle, which arises from the posterior surface of the medial end of the clavicle, the posterior sternoclavicular ligament, and the upper and posterior part of the manubrium sterni. ...

The central tendon of this muscle varies much in length and form, and is held in position by a process of the deep cervical fascia, which sheaths it, and is prolonged down to be attached to the clavicle and first rib; it is by this means that the angular form of the muscle is maintained. A tendon (or sinew) is a tough band of fibrous connective tissue that connects muscle to bone and is built to withstand tension. ...

Triangles The inferior belly of the Omohyoideus divides the posterior triangle of the neck into an upper or occipital triangle and a lower or subclavian triangle. The posterior triangle (or lateral cervical region) is bounded, in front, by the Sternocleidomastoideus; behind, by the anterior margin of the Trapezius; its base is formed by the middle third of the clavicle; its apex, by the occipital bone. ...
The occipital triangle, the larger division of the posterior triangle, is bounded, in front, by the Sternocleidomastoideus; behind, by the Trapezius; below, by the Omohyoideus. ...
The subclavian triangle, the smaller division of the posterior triangle, is bounded, above, by the inferior belly of the Omohyoideus; below, by the clavicle; its base is formed by the posterior border of the Sternocleidomastoideus. ...
Its superior belly divides the anterior triangle into an upper or carotid triangle and a lower or muscular triangle. The anterior triangle is bounded, in front, by the middle line of the neck; behind, by the anterior margin of the Sternocleidomastoideus; its base, directed upward, is formed by the lower border of the body of the mandible, and a line extending from the angle of the mandible to the...
The superior carotid triangle (or carotid triangle), is bounded, behind by the Sternocleidomastoideus; below, by the superior belly of the Omohyoideus; and above, by the Stylohyoideus and the posterior belly of the Digastricus. ...
The inferior carotid triangle (or muscular triangle), is bounded, in front, by the median line of the neck from the hyoid bone to the sternum; behind, by the anterior margin of the Sternocleidomastoideus; above, by the superior belly of the Omohyoideus. ...
The Omohyoid muscle is proximally attached to the scapula and distally attached to the hyoid bone. Left scapula - front view () Left scapula - rear view () In anatomy, the scapula, or shoulder blade, is the bone that connects the humerus (arm bone) with the clavicle (collar bone). ...
The hyoid bone (Os Hyoideum; Lingual Bone) is a bone in the human neck, not articulated to any other bone; it is supported by the muscles of the neck and in turn supports the root of the tongue. ...
Variations Doubling; absence; origin from clavicle; absence or doubling of either belly.
Innervation The omohyoid is innervated by a branch of the cervical plexus, and mostly acts to stabilise the hyoid bone. The cervical plexus is a plexus of the ventral roots of the first four cervical spinal nerves which are located from C1 to C4 cervical segment near the neck. ...
