Term
Two Divisions of Skeletal System
Definition
Axial- skull, vertebrae, ribcage
Appendicular- limbs, pectoral,pelvic girdles
Term
Five functions of bone
Definition
1.Support for the body
2.Protection of soft organs
3.movement
4.hematopoiesis
5.Storage of minerals and fat
Term
Two basic types of bone tissue
Definition
1.Compact Bone
2.Spongy Bone
Term
4 Groups of bones
Definition
1.Long (mostly compact, arms, legs)
2.Short (mostly spongy, ankles, wrists)
3.Flat (Skull, ribs, sternum)
4.Irregular (Vertebrae and Facial)
Term
What minerals make up the matrix of bone?
Definition
osteoblasts, osteoclasts
Term
2 Factors that influence bone remodeling
Definition
Muscle and gravity
and blood calcium levels
Term
How are blood calcium levels maintained?
Definition
IT blood calcium is too low, parathyroid hormone (PTH) stimulates osteoclasts to break bone down. IF it is too high, then calcitonin stimulates osteocytes to deposit more calcium into bones.
Term
Fracture repair by a physician
Definition
Reduction (realignment of bone)
Immobilazation (holding bone in place)
Term
Four steps of bodily fracture healing
Definition
Hematoma, Fibrocartilage, fibrocartialige callus, bony callus
Term
hematopoiesis
Definition
formation of blood cells (happens in red bone marrow or Hematopoitic tissue)
Term
ossification
Definition
turning into bone
Term
osteoblasts
Definition
form bone
Term
osteocytes
Definition
bone cells
Term
osteoclasts
Definition
break bone down
Term
Name of joint that connects skull bones
Definition
sutures
Term
How is a fetal skull different from an adults?
Definition
A fetal skull is 1/4 of its body, while an adults is 1/8. Also, a fetal skull is not completely formed, and has fontenels or soft spots.
Term
Why are fontenels necessary?
Definition
They are needed because they allow for compacting of the skull when passing through the cervix, and to allow for brain growth
Term

cervical
thoracic
lumbar
sacrum
coccyx
