Anatomy 1: The Final Material Flashcards
(106 cards)
- PROTECTION (rib cage, cranium, vertebrae)
- STORAGE AREA (99% of CA is stored in the bones)
- MOVEMENT (by means of tendons)
- SUPPORT ( framework were the soft tissues & bones attach themselves)
- HEMOPOESIS ( the formation of all cells in the blood)
Functions of the skeletal system
Osteology
The study of bones
Hemopoesis
The formation of all cells in the blood
Shape
Individual names
Bones are classified by…
206 in total, with the exception of 2:
How many bones make up the skeletal system?
Sutural (WORMIAN) bones
And
Sesamoid bones
Two bones not included in the 206 bones of the body
Sutural bones
“WORMIAN”
Are small irregular shaped bones that sometimes form along the line of fusion of the cranial bones
Sesamoid Bones
Any bone embedded in the tendon of a muscle
- Axial Skeleton
2. Appendicular Skeleton
