Chapter 7 Bone marrow and ossification

what happens in yellow bone marrow?

RBM-transport oxygen and carbon dioxide; it becomes saturated with fat and no longer involved in blood cell formation

Hyaline Cartilage

endochondral ossification -most bones

where is red bone marrow located?

ends of long bones (epiphyses, inside spongy bone) center of some other bones -spongy bone between compact bone

what is the embryonic skeleton composed of?f

fibrous Connective Tissue and hyaline cartilage

main function of red bone marrow?

formation of (primarily red) blood cells- HEMATOPOEISIS

where is red bone marrow found (age)

in almost all bones of infants and children

Fibrous connective tissue

intramembranous ossification connective -flat bone and irregular bones

Bone marrow

aka myeloid tissue soft connective tissue site of blood cell production found in medullary cavity of long bones (YELLOW) found in spaces of spongy bone (RED)

function of yellow bone marrow

as a person ages RBM is REPLACED by YBM

Red bone marrow

located at ends of long bones (epiphyses) center of some other bones (spongy bone sandwiched between inner layer of compact) found in almost all bones of infants and children Formation of blood cells-hematopoeisis

Where is Yellow bone marrow found?

middle of long bones -diaphysis
