The nose is flanked by two anatomical structures called the eyes. Each one consists of an eyeballsuspended inside a bony socket within the skull, named the orbit. Main arteries: Common carotid, external carotid, internal carotid and facial arteriesĬustom quiz: Neurovasculature of the nasal cavity Main nerves: maxillary nerve (CN V2), mandibular nerve(CN V3), vagus nerve (CN X), hypoglossal nerve (CN XII), and facial nerve(CN VII)Ĭontains hyoid bone, thyroid gland, parathyroid glands, pharynx and larynx externally divided into triangles, internally divided into compartments Main arteries: descending palatine, facial, lingual, and maxillary arteries Main nerves: facial nerve (CN VII) and vestibulocochlear nerve (CN VIII)Ĭonsists of teeth, tongue, hard and soft palates, uvula and tonsils, oropharynx Main arteries: external carotid, maxillary, and basilar arteries Main nerves: optic nerve (CN II), oculomotor nerve (CN III), trochlear nerve (CN IV), trigeminal nerve (CN V), and abducens nerve (CN VI)Ĭomprised of outer, middle and inner ears Nerves: olfactory nerve (CN I), ophthalmic nerve (CN V1), maxillary nerve (CN V2)Ĭonsists of ocular bulbs (eyeballs) with associated extraocular muscles located in orbits Key facts about head and neck anatomy SkullĬomprised of 22 bones: (Frontal bone, parietal bones (2), occipital bone, temporal bones (2), sphenoid bone, ethmoid bone, maxillae (2), inferior nasal conchae (2), lacrimal bones (2), nasal bones (2), palatine bones (2), vomer, zygomatic bones (2), mandibleĬomposed of nasal cartilages and nasal bones, anterior to nasal cavityĪrteries: facial, sphenopalatine, greater palatine, and ophthalmic arteries In addition, we’ll also cover the most important blood vessels and nerves supplying each region. In this topic page, we’ll learn about various anatomical aspects of the head and neck, such as the skull, eyes, teeth, nose, ears, and neck. On the other end, the head is durable enough to protect the fragile brain but intricately designed to facilitate the passage of the complex neurovascular network.
The neck is resilient enough to sustain a five kilogram weight 24/7, yet sufficiently mobile to move it in several directions.
The head and neck are two examples of the perfect anatomical marriage between form and function, mixed with a dash of complexity.
