Blood cell formation in the bone marrow | Hematopoiesis |
Two types of Marrow | Red (think WBC, RBC, Platelets) Yellow (think fat) |
Tips of long bone are called | Proximal Epiphysis Distal Epiphysis |
Shaft of bone is called | Diaphysis |
Wraps around the bone | Periosteum |
Located in the ends of long bones | Spongy Bone aka cancellous bone |
Types of Long Bones | Femur Humours Phallanges |
Types of Short bones | carpal of wrist tarsal of feet |
Type of flat bone | skull |
Type of Irregular bone | vertebrae |
Thin layer of hyaline cartilage covering the epiphysis | Articular Cartilage |
Very tight. No spaces. The wall of the Diaphysis is made of this. | Compact bone cortical bone |
Conects bone to bone | Ligaments |
Conects muscle to bone | Tendons |
Builds Bones | Osteoblasts |
Takes Bones Apart | Osteoclasts |
Mature Bone Cell | Osteocytes |
Bone forms between 2 layers of connective tissue | Intramembranous |
Bone growth starts as cartliage that bone latter replaces | Endochondral |
two divisions of the skeleton | Axial Skeleton Appendicular Skeleton |
Cranial Bones | 1.Frontal 2.Parietal 3.Occipital 4.Temporal 5.Spheniod 6.Ethmoid |
Sutures of the skull | 1.Sagittal 2.Coronal 3.Lambdoial 4.Squamosal |
Suture: midline between the two parietal bones | Sagittal |
Suture: between the frontal bone and the parietal bones | Coronal |
Suture: between the occipital and parietal bones | Lambdoidal |
Suture: between the temmporal and parietal bones | Squamosal |
'Soft Spots' on an infants skull | Fontanels |
Number of vertebrae (for this class) | 26 |
