Study Notes

Cranium and Functions

The cranium consists of 8 bones that protect the brain.
Major cranial bones include frontal, parietal, temporal, occipital, sphenoid, and ethmoid.

Key Nerves and Muscles

The greater palatine nerve innervates the posterior hard palate and lingual gingiva.
The masseter muscle is the strongest muscle responsible for mastication.
The sternocleidomastoid muscle divides the neck into anterior and posterior triangles.
The abducens nerve (6th cranial nerve) controls eye muscle movement.

Anatomy of the Head

The occipital region covers the occipital bone and is overlaid by the scalp.
The infraorbital region is located below the orbital area of the head.
The buccal area pertains to structures close to the inner cheek.
The lacrimal bones form part of the medial wall of the orbit.

Tongue and Salivary Structures

Circumvallate lingual papillae are the large papillae present on the tongue.
Salivary glands are responsible for saliva production, with the parotid gland being the largest.
The parotid duct, also known as Stensen's duct, opens into the oral cavity at the parotid papilla.

Jaw and Teeth Anatomy

The temporomandibular joint (TMJ) allows mandible movement and exhibits hinge and glide actions.
Temporomandibular disorder (TMD) refers to diseases involving the TMJ.
The mental foramen is located in the mandible.

Bone Structures

The maxilla forms the upper jaw and hard palate.
The mandible is the only movable bone of the skull, supporting dental structures.
The hyoid bone is a horseshoe-shaped structure where tongue and floor mouth muscles attach.

Vascular Supply

The inferior alveolar artery runs behind the ramus and has five branches.
The posterior superior alveolar artery supplies blood to maxillary molars, premolars, and gingival tissues.

Regions and Anatomical Considerations

The head consists of 11 regions: frontal, parietal, occipital, temporal, orbital, nasal, infraorbital, zygomatic, buccal, oral, and mental.
Cranial bones include specific names and numbers, highlighting their anatomical relevance.
