- frontal bone
- parietal bone (2)
- temporal bone (2)
- occipital bone
- sphenoid bone (keystone bone- articulates with all other cranial bones)
- ethmoid bone (deepest skull bone)
found on each side of the cranum, form the rounded back and upper sides of the cranium
located on both side of the foramen magnum.
- Large opening in base of occipital
bones forming part of the lateral surfaces and the base of the skull, and containing the organs of hearing.
- a saddle-shaped reion in the sphenoid midline. the seat of this saddle, called the hypophyseal fossa, surrounds the pituitary gland
- in sphenoid bone
- attaches dura mater, secures brain
From 'Bridge' of nose, rest of nose consists of cartilage
- Paired cheek bones
- Arch portion is frequently fractured
- forms sutures with maxilla, frontal bone, and temporal bones
The 2 bones which form the posterior portion of the hard palate and the floor of the nose. These bones join with the maxilla bones to complete the palate.
- small, thin, midline bone that occupies and divides the nasal cavity
- forms posteroinferiorpart of nasal septum
- sphenoid (via its wings)
- Malleus, incus, and stapes
- Articulate by means of synovial joints
- There are small, striated skeletal muscles associated with these middle ear ossicles that contribute to aspects of normal hearing.
-Fusion of three bones: Manubrium, body (gladiolus) and xiphoid process
-located in the neck region
-first one is the atlas
-second is the axis
dens: distinctive feature of axis
-serves as pivot point
- Heart shaped body Heart shaped body
- Long spinous process
- Transverse facets that articulate with ribs
A = transverse process
B = spinous process
D = vertebral foramen
E = centrum (body)
located in lower back (moose)
