The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
The maxillary artery, the larger of the two terminal branches of the external carotid artery, arises behind the neck of the mandible, and is at first imbedded in the substance of the parotid gland; it passes forward between the ramus of the mandible and the sphenomandibular ligament, and then runs, either superficial or deep to the lateral pterygoid muscle, to the pterygopalatine fossa.
The anterior nasal spine, or anterior nasal spine of maxilla, is a bony projection in the skull that serves as a cephalometric landmark. [1] The anterior nasal spine is the projection formed by the fusion of the two maxillary bones at the intermaxillary suture. It is placed at the level of the nostrils, at the uppermost part of the philtrum.
57746. Anatomical terms of bone. [edit on Wikidata] The infraorbital groove (or sulcus) is located in the middle of the posterior part of the orbital surface of the maxilla. Its function is to act as the passage of the infraorbital artery, the infraorbital vein, and the infraorbital nerve.
Anatomical terms of bone. [ edit on Wikidata] The alveolar process (/ ælˈviːələr, ˌælviˈoʊlər, ˈælviələr /) [ 1 ] is the portion of bone containing the tooth sockets on the jaw bones (in humans, the maxilla and the mandible). The alveolar process is covered by gums within the mouth, terminating roughly along the line of the ...
Plan of branches of internal maxillary artery. (Visible but not labeled.) The pterygoid branches of the maxillary artery, irregular in their number and origin, supply the lateral pterygoid muscle and medial pterygoid muscle . Branches of the maxillary artery.
This arch divides into a maxillary process and a mandibular process, giving rise to structures including the bones of the lower two-thirds of the face and the jaw. The maxillary process becomes the maxilla (or upper jaw, although there are large differences among animals [10]), and palate while the mandibular process becomes the mandible or lower jaw.
Maxillary hiatus. Medial wall of left orbit. Left maxilla. Nasal surface. The maxillary hiatus (also known as maxillary sinus ostium, maxillary ostium, or opening from the maxillary sinus) [citation needed] is the opening of a maxillary sinus into the middle nasal meatus of the nasal cavity. It is situated superoposteriorly upon the lateral ...
