A&P Review: The Skull Flashcards

Study Notes

Ethmoid

Forms superior and medial nasal conchae through its projections.
Contains the cribriform plate, a crucial structure for olfactory functions.
Features an upward protrusion known as the crista galli, often referred to as the "cocks comb."

Frontal

Known as the forehead bone, pivotal in cranium structure.

Hyoid

A small U-shaped bone located in the neck.
Serves as an attachment point for many tongue muscles.

Lacrimal

Tiny bones that house the tear ducts essential for tear drainage.

Mandible

The lower jaw of the skull, essential for mastication.
Features the mental foramen, an important passage for nerves.

Maxilla

Forms the anterior part of the hard palate, contributing to oral cavity structure.

Nasal

Comprises the bridge of the nose, important for facial aesthetics and structure.

Occipital

Located at the most posterior part of the cranium, contributing to skull shape.
Contains condyles that articulate with the atlas, allowing head movement.
Houses the foramen magnum, a significant opening for the spinal cord.

Palatine

Consists of posterior bones of the hard palate, aiding in oral and nasal cavity separation.

Parietal

Makes up much of the lateral and superior aspects of the cranium.

Sphenoid

A unique, irregular bat-shaped bone forming part of the cranial floor.
Contains the sella turcica, a prominence that houses the pituitary gland.

Temporal

Features the mastoid process, important for muscle attachment.
Houses styloid processes, which serve as attachment points for ligaments and muscles.
Contains the middle ear, integral for auditory function.

Vomer

Forms a major part of the nasal septum, dividing the nasal cavity.

Zygomatic

Known as the cheekbone, contributing to facial contour and structure.

Paranasal Sinuses

Four bones: ethmoid, frontal, maxilla, and sphenoid contain paranasal sinuses, aiding in reducing skull weight and resonating voice.

Alveoli

Mandible and maxilla contain alveoli, which bear teeth, crucial for dentition and function.
