immediate. Detects denser objects. Bones are white.
Term
CT scan
Definition
used to detect hemmorage or intracranial lesions. Bones appear white.
Term
MRI
Definition
very clear. Gray mater easily distinguished from white mater because of WATER content. Works with hydrogen content in tissue which is less bound in fat.

Term
intramembranous ossification
Definition
bones ossified without any preexisting cartilage
Term
endochondral ossification
Definition
bones develop with preexisting cartilage
Term
growth hormone

produced by pituitary, stimulates epiphyseal plates
Term
thyroid hormone
