Document Summary

Head and neck (reading material: chapter 6: pages 141-158; chapter 10: pages 269-272, 274, 277-280) Skull: rests on top of the superior part of spine, made up of 2 sets of bones (cranial and facial) Cranial bones: function: cranium encloses and protects the brain, create three different term concepts. Cranial vault (skull cap) : if you take the cap off the skull, you open the vault, exposing the cranial base. Cranial base (floor) : looking down onto the base/floor of the cranium. Cranial cavity: completely upside down skull, bottom of the cranial base/floor. Forms the lateral and inferior walls of the skull. Features: zygomatic process: bony projection from side of temporal bone. These are all points of attachment for some muscles. Very important because they represent the only two point of contact between the skull and spine related to vertebra. Sphenoid bone: can"t see very well, sit right in the middle of the base of the cranial floor.
