memorize

Section 2

Question Answer
Diaphysisthe shaft or central part of a long bone.
EpiphysisEnds of long bones. Mostly made up of spongy bone. The surface is covered with articular cartilage which reduces friction
Periosteumconnective tissue covering the Diaphysis of long bones
Articular cartilagecovers the surface of Epiphysise. Makes the end of these bones smooth and slippery. Reduces friction between bones and joints
Epiphyseal lineremnants of the Epiphyseal plate.
Epiphyseal plateGrowth plate made of hyaline cartilage. Later converted into bone after growing period ends
memorize

Section 3

Question Answer
Medullary Cavityfound within long bones. Contains bone marrow (mainly yellow)
Yellow bone Marrowstores fat
Red bone marrowmakes red and white blood cells
Osteocytesmakes bone hard and rigid. Mainly made of compact bone
Osteoblastsa cell that secretes the matrix for bone formation. Mature and become osteocytes
Osteoclastsresponsible for breaking down bony matrix
memorize

Section 4

Question Answer
Lacunaetiny cavities where osteocytes are located
Lamellaelayers of concentric circles
Canaliculitiny canals within bones that carry nutrients to bone cells and wastes away
Ossificationthe process where hyaline cartilage is converted to bone
Reductionthe realignment of broken bone ends
Hematomaa solid swelling of clotted blood within the tissues.
