Скачать или смотреть 10 MAJOR BONES OF THE SKULL, STRUCTURE AND FUNCTIONS

The skull is composed of 22 bones, divided into two main groups:

Cranial bones (8 bones) – Protect the brain and form the structure of the head:

Frontal bone (forehead)
Parietal bones (2) (top and sides of the skull)
Temporal bones (2) (sides of the skull, housing the inner ear)
Occipital bone (back of the skull, contains the foramen magnum)
Sphenoid bone (central skull bone connecting all cranial bones)
Ethmoid bone (supports nasal cavity and separates the brain from the nasal passages)
Facial bones (14 bones) – Form facial structure and support sensory organs:

Nasal bones (2) (bridge of the nose)
Lacrimal bones (2) (support the tear ducts)
Zygomatic bones (2) (cheekbones)
Maxilla (2) (upper jaw)
Mandible (1) (lower jaw, only movable skull bone)
Palatine bones (2) (form the hard palate)
Inferior nasal conchae (2) (inside nasal cavity)
Vomer (1) (forms part of the nasal septum)
These bones provide protection, support muscle attachment, and shape the face. Understanding skull anatomy is vital for medicine, dentistry, and forensic science.
