1. MAMMAOGY LABORATORY 1 SKULL and SKELETON
OBJECTIVES: After this laboratory session you should be able to a. Identify the bones of the appendicular skeleton and axial skeleton b. Identify the major bones of the skull c. Identify the various types of vertebrae and the components of a typical vertebra. d.Demonstrate examples of the various features of bone

2. THE SKELETON The Axial Skeleton The Appendicular Skeleton
the skull, vertebral column, and thoracic cage (ribs & sternum)
The Appendicular Skeleton
consists of the pectoral & pelvic girdles plus fore and hind limbs

3. The Skull (Lateral)
1. Nasal
2. Frontal
3. Parietal
4. Occipital
5. Lacrimal

4. The Skull (dorsal)
1. Nasal
2. Frontal
3. Parietal
4. Occipital
5. Lacrimal
6. Squamosal (temporal in humans)
7. Jugal (malar in humans)

14. Axial skeleton: Cervical vertbrae
Atlas and axis: first two cervicals
Cervical: possess transverse foramina

15. Axial skeleton: vertebral elements
Neural spine
Thoracic: attached to ribs
Lumbar: stout lower back vertebrae
Sacral: connected to the pelvis; sacral vertebrae are fused into a single element, the sacrum
Caudal: tail vertebrae
