How many bones in the human body?
206
functions of skeletal system
Support-#1 function, protection, movement facilitation, mineral storage, storage of energy, and hematopoiesis
Movement facilitation definition
Assists muscles in creating movement of the body
What is stored within bones
Minerals and fats
Hematopoiesis
Formation of blood cells including Erythrocytes- red blood cells, Leukocytes- white blood cells, and Thrombocytes- platelets
Bone cells
Osteogenic, Osteoblasts, Osteoclasts, and Osteocytes
Osteogenic
Bone stem cells, differentiate to types of bone cells.
Osteoblasts
Deposit minerals to build bone
Osteocytes
Maintains bone tissue
Osteoclasts
functions in resorption, the destruction of bone matrix
Ossification
Hardening process of connective tissues such as bones
Intramembranous Bone growth
Occurs in skull bones, convert membrane models to bone, periosteum- width wise growth
Endochondral Bone growth
Occurs in most of the skeletal bones, convert hyaline cartilage to bone, Epiphyseal plate- length wise growth. Chondra means cartilage
