Anatomy

Branches of the Maxillary Artery The maxillary artery is one of the terminal branches of the external carotid artery and supplies deep structures of the face, maxilla, nasal cavity, muscles of mastication, and cranial contents. It is classically divided into three parts based on its relationship to the lateral pterygoid muscle: the first (mandibular) division, […]

 Salivary Glands: Anatomy, Function, and Clinical Significance Salivary glands play a critical role in oral health, digestion, and protection of the teeth and oral tissues. These glands are responsible for producing saliva, an essential fluid that aids in chewing, swallowing, digestion, lubrication of oral tissues, and antimicrobial defense. Disorders of the salivary glands are common

Serratus Anterior – ribs 1-8 External oblique – ribs 5-12 When access pleural cavity, pierce above external oblique Temporal branch of CN VII – lies immediately beneath the temporoparietal fascia above the superficial layer of the temporalis fascia. Lingual nerve – lies above the mandibular 3rd molar alveolar crest 14% of the time. Marginal mandibular

Zone 1: clavicles to cricoid cartilage Zone 2: cricoid cartilage to the angle of the mandible (larges area of the neck and thus most likely to be injured with penetrating neck trauma) Zone 3: angle of the mandible to base of the skull (most difficult area for surgical access)  

Triangles of the Neck: Anatomy, Boundaries, and Clinical Significance Understanding the triangles of the neck is fundamental in anatomy, surgery, and clinical diagnosis. These triangular regions serve as important anatomical landmarks that help clinicians localize vital neurovascular structures, glands, and muscles. Mastery of neck triangles is essential for oral and maxillofacial surgery, head and neck

Genial Tubercle: Anatomy, Muscle Attachments, and Clinical Significance By Dr. Paul Mirdamadi The genial tubercles are critical anatomic landmarks located on the lingual surface of the anterior mandible. Although small in size, they serve as the attachment points for key muscles involved in tongue position, swallowing, mandibular movement, and airway patency. A thorough understanding of
