|
Definition
- Fibrous Outer Layer
- Cellular Inner Layer
|
|
|
Term
| Describe Perforating Fibers |
|
Definition
- created by osteoblasts in periosteum cellular layer
- strongly connect tendons, ligaments, and joint capsules to bone through periosteum
|
|
|
Term
|
Definition
- an incomplete cellular layer lining medullary cavity
- covers spongey bone and lines central canals

Term
| What is Endochondral Ossification? |
|
Definition
| The initial bone formation beginning in the embryo, uses cartilage as a small model |
|
|
Term
| When does intramembranous ossification occur? |
|
Definition
| begins as mesenchymal cells/stem cells differentiate into osteoblasts within embryonic tissue |
|
|
Term
|
Definition
| When bones grow out into small struts |
|
|
Term
Define Pituitary Growth Failure
|
|
Definition
| When a reduction in the growth hormone leads to reduced epiphyseal cartilage activity and short bones |
|
|
Term
|
Definition
| Occurs when epiphyseal cartilage grows unusally slowly |
|
|
Term
|
Definition
| When excessive cartilage formation at the epiphyseal cartialge causes long and slender limbs |
|
|
Term
|
Definition
| The result of the overproduction of growth hormone before puberty |
|
|
Term
| Define Fibrodysplasia Ossificans Progressiva (FOP) |
|
Definition
| A gene mutation that causes bone deposition around skeletal muscles; results in bones developing in unusal places |
|
|
Term
|
Definition
| When growth hormone levels rise after epiphyseal plates close, resulting in bones being thicker |
|

|
Definition
- Most abundant mineral in body
- roughly 99% of Ca deposited in skeleton
- causes a variety of physiological functions
|
|
|
Term
| Calcium levels are controlled by activites of ... |
|
Definition
- Intestines: absorb Calcium & Phosphate under hormonal control
- Bones: remodeling by osteoblasts & osteoclasts
- Kidneys: Calcium & phosphate loss in urine under hormonal control
