C. AXIAL SKELETON
1.Frontal, Occipital, Parietal, Temporal, Sphenoid, Ethmoid
2.Vomer, Mandible, Maxilla, Inferior nasal concha, Lacrimal, Zygomatic, Palatine, Nasal
3. Know about structures observed in lab.
4.Soft spot between skull bones in baby’s head. It allows squishing of skull during childbirth and for growth of brain.
5. Coronal suture between frontal and parietal bones; Sagittal suture between 2 parietal bones; Lambdoidal suture between occipital and parietal; Squamosal suture between temporal and parietal bones.
6. Zygomatic and Temporal
7. Ethmoid, Sphenoid, Maxilla, Palatine, Lacrimal, Zygomatic, Frontal
8. Pituitary gland
9. Vomer and perpendicular plate of Ethmoid
10. Palatine process of Maxilla and Palatine bones
11. Maxilla and Mandible
12. Hyoid. It has no articulations
13. Cervical – 7
Thoracic – 12
Lumbar – 5
Sacral – 5 fused making the sacrum
Coccyx – 3-5 fused
14. Intervertebral disc made of fibrocartilage. Inter- means between.
15. C1 is the atlas; C2 is the axis.
16. Odontoid process = Dens
17. Vertebral foramen housing spinal cord. The vertebral arch comprised of the pedicles laterally and the lamina dorsally. Extending from the vertebra are the spinous process dorsally and transverse process laterally. The ventral part of the vertebra is the body. The facets or articular process articulate with the vertebra above/below it.
18. Manubrium, body, xiphoid process
19. True rib has its own costal cartilage going to the sternum. 7 pair
False rib does not have its own costal cartilage going to the sternum 5 pair
Floating rib (which by definition is also false rib) has NO costal cartilage – 2 pair – 11 and 12.
