The mandibular nerve (V3) is the largest of the three divisions of the trigeminal nerve, the fifth cranial nerve (CN V).
A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery. or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli.
The internal pudendal artery is one of the three pudendal arteries that branches off the internal iliac artery, providing blood to the external genitalia.
In human anatomy, the basilar artery is one of the arteries that supplies the brain with oxygen-rich blood.
The auriculotemporal nerve is a branch of the mandibular nerve (V3) that runs with the superficial temporal artery and vein, and provides sensory innervation to various regions on the side of the head.
In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the left colic flexure to the upper part of the rectum, which includes the descending colon, the sigmoid colon, and part of the rectum. Proximally, its territory of distribution overlaps with the middle colic artery, and therefore the superior mesenteric artery. The SMA and IMA anastomose via the marginal artery of the colon and via Riolan's arcade. The territory of distribution of the IMA is more or less equivalent to the embryonic hindgut.
In human anatomy, inferior epigastric artery refers to the artery that arises from the external iliac artery and anastomoses with the superior epigastric artery. Along its course, it is accompanied by a similarly named vein, the inferior epigastric vein. These epigastric vessels form the lateral border of Hesselbach's triangle, which outlines the area through which direct inguinal hernias protrude.
The pterygoid plexus is a venous plexus of considerable size, and is situated between the temporalis muscle and lateral pterygoid muscle, and partly between the two pterygoid muscles.
The deep temporal nerves, branches of the mandibular division of the trigeminal nerve, are two in number, anterior and posterior. They pass above the upper border of the pterygoideus externus and enter the deep surface of the temporalis.
The maxillary artery supplies deep structures of the face. It branches from the external carotid artery just deep to the neck of the mandible.
The infratemporal fossa is an irregularly shaped cavity, situated below and medial to the zygomatic arch. It is not fully enclosed by bone in all directions, and it contains superficial muscles that are visible during dissection after removing skin and fascia: namely, the lower part of the temporalis muscle, the lateral pterygoid, and the medial pterygoid.
The masseteric nerve passes laterally, above the pterygoideus externus, in front of the temporomandibular articulation, and behind the tendon of the temporalis; it crosses the mandibular notch with the masseteric artery, to the deep surface of the masseter, in which it ramifies nearly as far as its anterior border.
The masseteric fascia is a strong layer of fascia derived from the deep cervical fascia on the human head and neck. It covers the masseter, and is firmly connected to it. Above, this fascia is attached to the lower border of the zygomatic arch, and behind, it invests the parotid gland proceeding into the parotid fascia.
Masseteric is an adjective meaning "of or pertaining to the Masseter muscle", such as:
In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta:
The following outline is provided as an overview of and topical guide to human anatomy:
The parotid fascia in human anatomy is a fascia that builds a closed membrane together with the masseteric fascia. This common membrane sheaths the parotid gland, its excretory duct and the passing out branches of the facial nerve as well. The parotid fascia proceeds of the superficial layer of the deep cervical fascia that splits to cover the gland. At the lateral side of the gland this fascia is called the parotid fascia. The fascia itself is made of two layers: A superficial layer that passes cranial into the temporal fascia and lateral into the masseteric fascia, and a deeper layer that covers the Stylohyoid muscle, the styloglossus and the Musculus stylopharyngeus. The superficial layer is attached to the zygomatic arch above and to the mandible below.

Gray's Anatomy is an English language textbook of human anatomy originally written by Henry Gray and illustrated by Henry Vandyke Carter. Earlier editions were called Anatomy: Descriptive and Surgical, Anatomy of the Human Body and Gray's Anatomy: Descriptive and Applied, but the book's name is commonly shortened to, and later editions are titled, Gray's Anatomy. The book is widely regarded as an extremely influential work on the subject, and has continued to be revised and republished from its initial publication in 1858 to the present day. The latest edition of the book, the 41st, was published in September 2015.
