maxillary artery three parts branches detailed anatomy MBBS

Detailed anatomical diagram for MBBS seminar: PART 1 (Mandibular Part) of the Maxillary Artery. The diagram shows the origin of the maxillary artery as the larger terminal branch of the external carotid artery, passing between the neck of the mandible and the sphenomandibular ligament. Label all 5 branches with arrows and text boxes showing what each supplies: (1) Deep Auricular Artery - supplies external auditory meatus and tympanic membrane; (2) Anterior Tympanic Artery - supplies middle ear/tympanic cavity; (3) Middle Meningeal Artery - passes through foramen spinosum, supplies dura mater and cranial cavity walls, clinically significant in epidural hematoma; (4) Accessory Meningeal Artery - passes through foramen ovale, supplies trigeminal ganglion and dura; (5) Inferior Alveolar Artery - enters mandibular foramen, gives mylohyoid branch, supplies mandibular teeth then exits as mental artery at mental foramen supplying chin. Include a small inset box titled 'CLINICAL PEARL: Middle Meningeal Artery' noting it is the largest meningeal vessel and that rupture causes epidural/extradural hematoma. Use a clean medical illustration style with red arteries on white/light background, bold black labels, suitable for a seminar presentation slide.

Detailed anatomical diagram for MBBS seminar: PART 2 (Pterygoid Part) of the Maxillary Artery. The diagram shows the second part of the maxillary artery as it runs along the lateral pterygoid muscle in the infratemporal fossa. Label all 5-6 branches with arrows and text boxes: (1) Anterior Deep Temporal Artery - ascends between temporalis and pericranium, supplies anterior temporalis muscle; (2) Posterior Deep Temporal Artery - supplies posterior temporalis muscle; (3) Masseteric Artery - passes through mandibular notch, supplies masseter muscle; (4) Pterygoid Branches (Medial and Lateral Pterygoid Arteries) - supply pterygoid muscles; (5) Buccal Artery - runs with long buccal nerve, supplies buccinator muscle and buccal mucosa. Show the lateral pterygoid muscle clearly as the key landmark dividing Part 1 from Part 2. Include a title banner 'PART 2 - PTERYGOID (MUSCULAR) PART: Supplies Muscles of Mastication'. Use a clean medical illustration style with red arteries, labeled muscles shown in different shades, bold black text labels, suitable for a seminar slide.

Detailed anatomical diagram for MBBS seminar: PART 3 (Pterygopalatine Part) of the Maxillary Artery. The diagram shows the third part of the maxillary artery entering the pterygopalatine fossa through the pterygomaxillary fissure. Label all 6 branches with arrows and text boxes: (1) Posterior Superior Alveolar Artery - enters posterior alveolar foramina, supplies upper molar and premolar teeth and maxillary sinus; (2) Infraorbital Artery - runs in infraorbital groove and canal, exits infraorbital foramen, supplies lower eyelid, upper lip, cheek; (3) Descending Palatine Artery - divides into greater palatine (hard palate) and lesser palatine (soft palate and tonsil); (4) Artery of Pterygoid Canal (Vidian Artery) - supplies upper pharynx and auditory tube; (5) Pharyngeal Artery - supplies roof of nasopharynx and sphenoidal sinus; (6) Sphenopalatine Artery (terminal branch) - passes through sphenopalatine foramen, supplies lateral nasal wall and septum, site of Kiesselbach plexus, most common source of epistaxis. Include a clinical pearl box: 'Sphenopalatine artery = most common cause of posterior epistaxis'. Use clean medical illustration style with red arteries, labeled structures, bold text, suitable for a seminar slide.
