Anatomy Packet 3 – Flashcards

There are _____ facial bones

Paired, oblong shaped bones that sit side by side and form the bridge of the nose.

Paired maxillae (single= maxilla) unite to form the upper jaw. They articulate with every other facial bone except for the mandible.

The maxillae help to form the

The maxillae contains the

The maxillary sinus is also known as the

Horse-shoe shaped structure that contain the alveolar sockets. Each contains 16 alveolar sockets (where teeth come in from the upper jaw)

Hold the teeth

Horizontal portion that forms the anterior portion of the hard palate

Cheek bones. Help form the prominences of our cheeks and outer lateral wall and floor of the eye orbits

Projects posteriorly from the zygomatic bone. Articulates with the zygomatic process of the temporal bone forming the zygomatic arch

A singular bone that forms the lower jaw; it is the largest and strongest of the facial bones, and is the only moveable bone of the skull.

Horizontal portion of the mandible. A singular bone separated in the middle - 2 bodies - one on each side

Perpendicular portion of the mandible. Also described as the vertical portion- 1 on each side

Bend or curve portion of the mandible between the body and the ramus. Area where the body meets the ramus

Each ramus has a ___________ and ________________ portion

Called the condylar process which articulated with the mandibular fossa of the temporal bone, forming the tempormandibular joint

Contains the coronoid process which serves as a point of attachment for the temporalis muscle.

The posterior extension of the mandibular ramus consisting of a narrow neck and round head

Sharply angled anterior extension from the mandibular ramus; attachment point for the temporalis muscle

A notch depression between the condylar and coronoid processes

2, paired thin bones the size and shape of fingernails. The smallest of the facial bones. Located posterior and lateral to the nasal bones. Help form the medial borders of the eye orbits

2, L shaped bones. Form the posterior portion of the hard palate, part of the floor and lateral wall of the nasal cavity and a very small portion of the eye orbit

Actual part of the bone that forms the posterior portion of the hard pallet

2 thin scroll shaped bones on the lateral walls of the nasal cavities. Primary roll- act as a filter and warm the air. Located inferior to the middle conchae completely independent of the superior and middle conchae of the ethmoid

Single triangular shaped bone forms the inferior and posterior portion the nasal septum. Superior border articulates with the perpendicular plate of the ethmoid bone

This is formed by three structures: Perpendicular plate of the ethmoid bone, the vomer, and the septal cartilage.

Thin vertical plate that extends down into the nasal cavity, articulates with the vomer to form the bony nasal septum. Forms the superior portion of the nasal septum

Forms the anterior and inferior border (rubber piece you can wiggle)

There are 4 para-nasal sinuses or nasal sinuses

There are 7 bones that help form the eye socket

A singlular, U shaped bone located in the cervical region, inferior to the mandible and superior to the larynx (specifically the thyroid cartilage of the larynx). Suspended from the styloid process of the temporal bone by ligaments and muscles. It supports the tongue providing attachment sites of the tongue muscles and neck muscles; does not articulate with any other bones
