BONES OF THE SKULL – Flashcards

Includes forehead, part of nasal cavity, main portion of the roof of the eye orbits, and the nose

There are 2 parietal bones one on each side of the head. They form the sides and roof of the skull & are joined at the midline by the saggtal suture. They join the occipital, the frontal, the temporal, & the sphenoid bones.

22 BONES MAKE UP THE CRANIAL BONES. ONE FRONTAL, TWO PARIETAL, TWO TEMPORAL, ONE SPHENOID, ONE OCCIPITAL, AND ONE ETHMOID.

LOCATED AT THE SIDES AND BASE OF THE SKULL. PROJECTING FROM THE ANTERIOR PORTION OF EACH TEMPORAL BONE IS THE ZYGOMATIC PROCESS, WHICH MEETS THE ZYGOMATIC BONE (CHEEKBONE). LOWER PORTION OF THIS FAN SHAPED BONE INCLUDES A DEPRESSION CALLED THE GLENOID FOSSA WHICH IS A SHALLOW DEPRESSION THAT ARTICULATES, OR JOINS WITH, THE MANDIBLE.

Also called the "butterfly bone" articulates with all the other cranial bones to bind them together. The greater wings of the sphnoid bone form the sides of the skull and are located anterior to the temporal bones.

A light spongy bone situated between the 2 orbits of the eyes. It forms the bony wall of the nasal septum and encases the ethmoid sinuses.

Situated at the back (posterior) and base of the cranium. A large opening called the FORAMEN MAGNUM allows the spinal cord to pass through this bone into the brain.

THERE ARE 13 STATIONARY BONES AND ONE MOVABLE BONE. ONLY THE MANDIBLE (JAW) MOVES. THEY FORM THE BASIC SHAPE OF THE FACE AND PROVIDE ATTACHMENT FOR THE FACIAL MUSSCLES.

Small oblong bones that are fused at the midline and form the bridge of the nose.They articulate (join) with the frontal, ethmoid, and maxillary bones.

THE 2ND LARGEST BONE OF THE FACE. MADE UP OF 2 PORTIONS JOINED BY A MEDIAN SUTURE. SPONGY/POROUS/CANCELLOUS TYPE OF BONE.

THICKEST & MOST SPONGY PART OF THE MAXILLARY BONE & CONTAINS SOCKETS FOR THE TEETH.

THE MOST POSTERIOR PORTION OF THE MAXILLARY ALVEOLAR BONE, BEHIND THE MOLARS, AND IS A ROUNDED PROJECTION OF A BONE

The smallest and most fragile bones of the face. They are very thin; situated at the front part of the inner wall of the eye orbit anterior to the ethmoid bones; and CONTAIN THE TEAR DUCTS.

THE ZYGOMATIC OR MALAR BONE, IS A PAIRED BONE, WITH ONE ON EACH SIDE OF THE HUMAN SKULL.

CONSIST OF A HORIZONTAL AND VERTICAL PLATE. THE HORIZONTAL PLATE FORMS THE HARD PALATE AND CONTAINS THE MEDIAN PALATINE SUTURE. THE VERTICAL PLATE IS A THIN OBLONG FORM THAT RISES UP BEHIND THE NOSE TO MEET THE ORBITS OF THE EYES. IT IS THE SOFT AND HARD PALATE. IF THIS PALATE IS OPEN IT IS CALLED A CLEFT PALATE.

Each side of the outer wall of the nasal fossa has a thin layer of curled bone called the inferior turbinate, ALSO KNOWN AS THE INFERIOR NASAL CONCHA. These bones provide support for the mucous membranes.

It's a single bone situated vertically at the back of the nasal fossa, and FORMS PART OF THE SEPTUM/PORTION OF THE NOSE.

DERIVED FROM LATIN WORD MEANING, TO CHEW. THE LONGEST AND STRONGEST BONE OF THE FACE (IT'S U SHAPED) AND HOLDS THE TEETH OF THE LOWER JAW.

PAD OR SPACE THAT'S LOCATED DISTAL (to the rear) OF THE 3RD MOLAR.

INSIDE OF THE JAW/MANDIBLE - SLANTED BONY GROWTH RIDGE

SMALL OPENING SITUATED ON THE LEFT AND RIGHT ANTERIOR AREAS OF THE MANDIBLE USED FOR THE PASSAGE OF NERVES AND BLOOD VESSELS.

OUTSIDE OF THE JAW/MANDIBLE. SLANTED BONY GROWTH RIDGE ON THE FACIAL SIDE OF THE MANDIBLE.

PART OF THE MANDIBLE THAT RESTS IN A DEPRESSION IN THE TEMPORAL BONE CALLED THE GLENOID OR MANDIBULAR FOSSA.

UNION OF THE JOINTS OF THE TEMPORAL AND MANDIBULAR BONES. COMPOSED OF CONDYLE OF THE MANDIBLE AND THE GLENOID FOSSA. IS RESPONSIBLE FOR THE VERTICLE & LATERAL MOVEMENT OF THE LOWER JAW.

A U SHAPED BONE THAT'S SUSPENDED IN THE NECK AND ATTACHED TO THE NECK BY MUSCLES OF THE TONGUE. IT SUPPORTS THE TONGUE AND PROVIDES ATTACHMENT FOR NUMEROUS MUSCLES
