Study Notes
Key Terms
- Fundamental vocabulary essential for understanding head and neck anatomy.
Regions of the Head
- The head is divided into 11 distinct regions:
- Frontal
- Parietal
- Occipital
- Temporal
- Orbital
- Nasal
- Infraorbital
- Zygomatic
- Buccal
- Oral
- Mental
Bones of the Cranium and Face
- Cranium consists of:
- Frontal
- Parietal
- Occipital
- Temporal
- Sphenoid
- Ethmoid
- Facial bones include:
- Zygomatic
- Maxillary
- Palatine
- Nasal
- Lacrimal
- Vomer
- Inferior conchae
- Mandible
- Contains 6 auditory ossicles:
- Malleus
- Incus
- Stapes
Muscles of the Head and Neck
- Neck muscles:
- Sternocleidomastoid
- Trapezius
- Facial expression muscles include:
- Orbicularis oris
- Buccinator
- Mentalis
- Zygomatic major
- Muscles for mastication are:
- Temporal
- Masseter
- Internal pterygoid
- External pterygoid
- Tongue muscles:

- Geniohyoid
Blood Vessels of the Head and Neck
- Key arteries include:
- External carotid artery
- Facial artery
- Lingual artery
- Mandibular artery
- Maxillary artery
Temporomandibular Joint Components
- Notable structures:
- Capsular ligament
- Meniscus (articular disc)
- Synovial fluid
Action of the Temporomandibular Joint
- Facilitates movement of the mandible for:
- Speech
- Mastication
Salivary Glands and Ducts
- Minor salivary glands:
- Numerous and smaller than major glands
- Major salivary glands:
- Parotid (Stensen's duct)
- Submandibular (Wharton's duct)
- Sublingual (Bartholin's duct)
Divisions of the Trigeminal Nerve
- Divided into three main branches:
- Ophthalmic
- Maxillary
- Mandibular
Major Lymph Node Sites
- Major lymph node groups in the body:
- Cervical nodes (superficial and deep)
- Axillary nodes
- Inguinal nodes
Paranasal Sinuses of the Skull
- Major paranasal sinuses:
- Maxillary sinuses
- Frontal sinuses
- Ethmoid sinuses
- Sphenoid sinuses
Clinical Integration of Knowledge
- Understanding nerves is crucial for local anesthesia in dental treatments.
- Blood vessels may contribute to the spread of infections in the head and neck.
- Muscle dysfunction could lead to issues like malocclusion, temporomandibular disorders (TMD), and dental infection spread.
