In human anatomy, the sternocleidomastoid muscles are muscles in the neck that act to flex and rotate the head. ...
The omohyoid muscle is a muscle at the front of the neck that consists of two bellies separated by an intermediate tendon. ...
The digastric muscle (named digastric as it has two bellies) is a small muscle located under the jaw. ...
It is covered by the integument, superficial fascia, Platysma and deep fascia; ramifying in which are branches of the facial and cutaneous cervical nerves. Its floor is formed by parts of the Thyrohyoideus, Hyoglossus, and the Constrictores pharyngis medius and inferior. The platysma is a superficial muscle that stretches from the clavicle to the mandible overlapping the sternocleidomastoid. ...
The Hyoglossus is a muscle of the human body. ...
This space when dissected is seen to contain the upper part of the common carotid artery, which bifurcates opposite the upper border of the thyroid cartilage into the external and internal carotid. These vessels are somewhat concealed from view by the anterior margin of the Sternocleidomastoideus, which overlaps them. The cartilages of the larynx. ...
The external and internal carotids lie side by side, the external being the more anterior of the two.
The following branches of the external carotid are also met with in this space: the superior thyroid, running forward and downward; the lingual, directly forward; the external maxillary, forward and upward; the occipital, backward; and the ascending pharyngeal, directly upward on the medial side of the internal carotid.
The veins met with are: the internal jugular, which lies on the lateral side of the common and internal carotid arteries; and veins corresponding to the above-mentioned branches of the external carotid—viz., the superior thyroid, the lingual, common facial, ascending pharyngeal, and sometimes the occipital—all of which end in the internal jugular. Many animals have longer and more flexible tongues than humans. ...

The nerves in this space are the following.
In front of the sheath of the common carotid is the ramus descendens hypoglossi.
The hypoglossal nerve crosses both the internal and external carotids above, curving around the origin of the occipital artery. The hypoglossal nerve is the twelfth cranial nerve. ...
occipital artery ...
Within the sheath, between the artery and vein, and behind both, is the vagus nerve; behind the sheath, the sympathetic trunk. The vagus nerve (also called pneumogastric nerve or cranial nerve X) is the tenth of twelve paired cranial nerves, and is the only nerve that starts in the brainstem (within the medulla oblongata) and extends, through the jugular foramen, down below the head, to the abdomen. ...
The sympathetic trunk (sympathetic chain, gangliated cord) is a bundle of nerve fibers that runs from the base of the skull to the coccyx. ...
On the lateral side of the vessels, the accessory nerve runs for a short distance before it pierces the Sternocleidomastoideus; and on the medial side of the external carotid, just below the hyoid bone, may be seen the internal branch of the superior laryngeal nerve; and, still more inferiorly, the external branch of the same nerve. The accessory nerve is the eleventh of twelve cranial nerves. ...
In human anatomy, the sternocleidomastoid muscles are muscles in the neck that act to flex and rotate the head. ...
In human anatomy, the external carotid artery is a major artery of the head and neck. ...
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. ...
The Superior Laryngeal Nerve arises from the middle of the ganglion nodosum and in its course receives a branch from the superior cervical ganglion of the sympathetic. ...
The upper portion of the larynx and lower portion of the pharynx are also found in the front part of this space.
