WFC 110L Lab 1 Skull and Bones

skull

compromises the cranium and mandible

Cranium

includes the braincase and rostrum (top part)

mandible

lower Jaw

braincase

the portion of the skull that encloses the brain

rostrum

top jawbone stuff

nasal bones

form the bridge of the nose

premaxillary bones

maxillary bones

diastema

Gap between teeth

frontal bone

Postorbital process

of the frontal bone

Postorbital process

of the zygoma; extends dorsally and may meet with the postorbital process of the frontal to form a postorbital bar or plate

Postorbital bar

a bony ring encircling the lateral side of the eye but not forming a complete cup around the eye globe

Postorbital plate

A bony plate that provides protection to the side and back of the eye.

Parietal bones

Interparietal bone

- only some mammals have it

- Single bone between the parietal bones on posterior end of skull

Squamosal bones

jugal bones

Lacrimal bones

Lacrimal foramen

hole located at the distal end of the lacrimal bone; tear duct

Zygomatic arch

Comprised of both the jugal and squamosal bones

Zygomatic spine

Process of the zygomatic plate

Zygomatic plate

orbits

eye sockets

Temporal fossae

fossa (shallow depression) on the side of the skull bounded by the temporal lines above, and the zygomatic arch below.

Temporal ridge

V-shaped ridge superior to frontal.

Occipital bone

occipital crest

Sagittal crest

Supraoccipital bone

Most posterior part of the skull base

Basioccipital bone

Occipital condyles

Two bony protuberances located at the base of the occipital bone

Exoccipital process

Paroccipital process

Mastoid process
