Anatomical terminology

In human anatomy, the superficial temporal artery is a major artery of the head. It arises from the external carotid artery when it splits into the superficial temporal artery and maxillary artery.

Contents

Its pulse can be felt above the zygomatic arch, above and in front of the tragus of the ear.

Structure

The superficial temporal artery is the smaller of two end branches that split superiorly from the external carotid. Based on its direction, the superficial temporal artery appears to be a continuation of the external carotid.

It begins within the parotid gland, behind the neck of the mandible, and passes superficially over the posterior root of the zygomatic process of the temporal bone; about 5 cm above this process it divides into two branches: a. frontal, and a. parietal.

Branches

The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head. It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries.

The frontal branch of the superficial temporal artery (anterior temporal) runs tortuously upward and forward to the forehead, supplying the muscles, skin, and pericranium in this region, and anastomosing with the supraorbital and frontal arteries. In an estimate of the path of the nerve in the soft tissue of the temporal frontal branch using landmarks by Pitanguy, he describes a line starting from a point 0.5 cm below the tragus in the direction of the eyebrow, passing 1.5 cm above the lateral extremity of the eyebrow.

Relations

As it crosses the zygomatic process, it is covered by the auricularis anterior muscle and by a dense fascia; it is crossed by the temporal and zygomatic branches of the facial nerve and one or two veins, and is accompanied by the auriculotemporal nerve, which lies immediately behind it.

The superficial temporal artery joins ( anastomoses ) with, among others, the supraorbital artery of the internal carotid artery.

Clinical significance

The superficial temporal artery is often affected in giant-cell arteritis and biopsied if the diagnosis is suspected.

External carotid artery Major artery of the head and neck

The external carotid artery is a major artery of the head and neck. It arises from the common carotid artery when it splits into the external and internal carotid artery. External carotid artery supplies blood to the face and neck.

Internal carotid artery Artery of the human brain

The internal carotid artery is located in the inner side of the neck in contrast to the external carotid artery. In human anatomy, they arise from the common carotid arteries, where these bifurcate into the internal and external carotid arteries at cervical vertebrae C3 or C4; the internal carotid artery supplies the brain, including the eyes, while the external carotid nourishes other portions of the head, such as the face, the scalp, the skull, and the meninges.

Scalp Anatomical area bordered by the human face at the front, and by the neck at the sides and back

The scalp is the anatomical area bordered by the human face at the front, and by the neck at the sides and back.

Auriculotemporal nerve Branch of the mandibular nerve

The auriculotemporal nerve is a branch of the mandibular nerve (CN V3) that runs with the superficial temporal artery and vein, and provides sensory innervation to various regions on the side of the head.

Temporal fossa

The temporal fossa is a fossa on the side of the skull bounded by the temporal lines and terminating below the level of the zygomatic arch.

Occipital artery

The occipital artery arises from the external carotid artery opposite the facial artery. Its path is below the posterior belly of digastric to the occipital region. This artery supplies blood to the back of the scalp and sternocleidomastoid muscles, and deep muscles in the back and neck.

Superior thyroid artery

The superior thyroid artery arises from the external carotid artery just below the level of the greater cornu of the hyoid bone and ends in the thyroid gland.

Posterior auricular artery Small artery

The posterior auricular artery is a small artery that arises from the external carotid artery, above the digastric muscle and stylohyoid muscle, opposite the apex of the styloid process.

Maxillary artery

The maxillary artery supplies deep structures of the face. It branches from the external carotid artery just deep to the neck of the mandible.

Superficial temporal vein

The superficial temporal vein is a vein of the side of the head. It begins on the side and vertex of the skull in a network of veins which communicates with the frontal vein and supraorbital vein, with the corresponding vein of the opposite side, and with the posterior auricular vein and occipital vein. It ultimately crosses the posterior root of the zygomatic arch, enters the parotid gland, and unites with the internal maxillary vein to form the posterior facial vein.

Squamous part of temporal bone Front and upper part of the sides of the skull base

The squamous part of temporal bone, or temporal squama, forms the front and upper part of the temporal bone, and is scale-like, thin, and translucent.

Middle cranial fossa

The middle cranial fossa, deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior fossa by the clivus and the petrous crest.

Deep cervical fascia

The deep cervical fascia lies under cover of the platysma, and invests the muscles of the neck; it also forms sheaths for the carotid vessels, and for the structures situated in front of the vertebral column. Its attachment to the hyoid bone prevents the formation of a dewlap.

Temporal fascia

The temporal fascia covers the temporalis muscle.

The submandibular triangle corresponds to the region of the neck immediately beneath the body of the mandible.
