Bontrager Chapter 11 Workbook And Self Test - JUST SKULL
Cranial Anatomy and Bone Articulations
1. Bones Not Part of the Cranial Floor:
- Occipital is not part of the floor of the cranium (correctly identified).
2. Frontal Bone:
- The thin-walled aspect that forms the forehead is called the squamous part.
- Articulates with:
- Right parietal
- Left parietal
- Sphenoid
- Ethmoid
3. Widest Aspect of the Skull:
- Found at the parietal tubercles of two parietal bones.
4. Prominent Landmark of the Occipital Bone:
- External occipital protuberance (inion) is a notable bump.
### Articulating Bones
- Parietal Bone: 5 articulating bones
- Occipital Bone: 6 articulating bones
- Temporal Bone: 3 articulating bones
- Sphenoid Bone: 7 articulating bones
- Ethmoid Bone: 2 articulating bones
### Cranial Structures and Landmarks
1. Thickest and Densest Structure:
, - Petrous portion of the temporal bone.
2. Hypophysis:
- Another term for the pituitary gland (True; hypophysis cerebri).
3. Sphenoid Bone:
- Articulates with all other cranial bones (True).
4. Clivus:
- The shallow depression just posterior to the base of the dorsum sellae and anterior to the foramen
magnum.
5. Crista Galli:
- The small section located superior to the cribiform plate.
6. Left Sphenoid Fontanel in Adults:
- Termed the left pterion.
7. Squamosal Suture:
- Formed by the inferior junction of the parietal bones to the temporal bones.
8. Small, Irregular Bones in Skull Sutures:
- Sutural (Wormian) bones.
### Structures within Specific Bones
1. Sphenoid:
- Contains pterygoid hamulus, anterior clinoid processes, foramen ovale, and sella turcica.
2. Frontal:
