Anatomy Course Connects the superior and inferior mesenteric arteries in the gut. Formed when an anastomosis forms between the right, middle and left colic arteries, as well as the ileocolic artery. It runs in the mesentery with the other vessels of the bowel. Supply Supplies the bowel with blood, in conjunction with the other branches

Anatomy Origin: Superficial and Deep portion: Inferior border and medial surface of zygomatic arch. Insertion: Superficial and Deep portion: Outer aspect of angle of jaw and lower half of ramus of mandible. Key Relations: -The superficial portion is larger and thicker whereas the deep portion is much smaller. -The muscle is crossed superficially by the

Anatomy Course The final vein of the pterygoid plexus. It is a short vein and it flows into the retromandibular vein. Eventually it flows into the external carotid vein. Drain Drains the deep structures of the face. Interested in taking our award-winning Pocket Anatomy app for a test drive?

Anatomy Course A branch of the external carotid artery. It begins just behind the neck of the mandible, and passes forward just beneath the bone and then through the infratemporal fossa. The artery then enters the pterygopalatine fossa by passing through the pterygomaxillary fissure. Once in the pterygopalatine fossa it splits into several terminal branches.

Anatomy The midline symphysis menti marks the fusion of left and right parts of body of mandible. It spreads at its inferior end, forming a forward mental protuberance and on each side, a small mental tubercle. Oblique line ends here. Vignette Chin dimple when there is incomplete fusion of right and left parts of body

Anatomy The midline symphysis menti marks the fusion of left and right parts of body of mandible. It spreads at its inferior end, forming a forward mental protuberance and on each side, a small mental tubercle. Vignette Chin dimple when incomplete fusion of right and left parts of body of mandible (or of muscle). Inherited

Anatomy At back of top of ramus, separated from coronoid process by the mandibular notch. Process consists of neck and head. Articulates with glenoid fossa of temporal bone at the TMJ (tempero-mandibular joint), a synovial joint with an articular disc. Tempero-mandibular ligament attached at lateral extremity of condyle. Vignette TMJ pain common in muscles of

Anatomy The perpendicular part of the mandible, its upper extremities consisting of the coronoid and condylar processes, with the mandibular notch between. Laterally, almost fully covered by masseter; postero-medially, pterygoid. Clinical The mandible (jawbone) holds the lower teeth. Chews. involved in speech. Along with cranium, makes up skull. Four parts (each side): Anterior (left and

Anatomy Consists of a ridge. Begins faintly anteriorly where it begins at mental tubercle (chin), more evident as it courses back and up to become continuous with anterior border ramus. Clinical Attachment for depressor anguli oris, quadratus labii inferioris. Interested in taking our award-winning Pocket Anatomy app for a test drive?
