The carotid triangle (or superior carotid triangle) is a portion of the anterior triangle of the neck. Anatomy. Boundaries. It is bounded: ...
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 sternocleidomastoid; above, by the superior belly of the omohyoid.
Superficial dissection of the right side of the neck, showing the carotid and subclavian arteries. At the lower part of the neck, the common carotid artery is very deeply seated, being covered by the integument, superficial fascia, the platysma muscle, deep cervical fascia, the sternocleidomastoid muscle, the sternohyoid, sternothyroid, and the ...
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
Sternocleidomastoid branch: This branch divides into upper and lower branches in the carotid triangle. The upper branch accompanies the accessory nerve to the sternocleidomastoid, and the lower branch arises near the origin of the occipital artery before entering the sternocleidomastoid muscle. Occasionally, this branch arises directly from the ...
The lower border of the body of the mandible, and a line extending from the angle of the mandible to the mastoid process Investing fascia covers the roof of the triangle while visceral fascia covers the floor.
The external carotid artery arises from the common carotid artery just inferior to the upper border of the thyroid cartilage. [1]At its origin, this artery is closer to the skin and more medial than the internal carotid, and is situated within the carotid triangle.
The superior root is situated within the carotid triangle. [1]: 344 It passes anterior-ward between the internal carotid artery and the common carotid artery. [1]: 500 It curves around the occipital artery [citation needed] before descending upon the anterior aspect of the internal carotid artery and the common carotid artery.
