Bones Continued: Ossification, Homeostasis, and Fractures

One of the two processes of embryonic bone formation: most flat bones and a few other bones in a sheet of dense fibrous connective tissue

One of the two processes of embryonic bone formation: most long, short, or irregular bones in a mass of dense fibrous connective tissue

Connective tissue stem cells which synthesize and secrete the matrix of cartilage

Mature connective tissue cells found within the lacunae of cartilage matrix

Embryonic precursor to mature bone for most long bone, short and irregular bones which form by endochondral ossification

In long bones forming by the process of endochondral ossification, the sheet of hyaline cartilage which develops between growing bone matrix of the diaphysis and the epiphysis

The slightly thickened plate of sponge bone observed in the interior of long bones where an epiphyseal plate of cartilage had been present earlier in development

The region of a long bone between the diaphysis and the epiphysis, generally, the are within a long bone associated with the epiphyseal line or plate

The ability to maintain internal equilibrium of bone matrix density on the one hand and blood calcium and phosphate ion levels on the other hand by adjusting negative feedback

The ongoing and continual activity of osteoclasts and osteoblast in the periosteum and endosteum

An abnormally high concentration of calcium ions in the blood, at worst cardiac arrest may occur

An abnormally low concentration of calcium ions in the blood; at worst respiratory failure may occur

The ability to maintain internal equilibrium of blood calcium and phosphate ion levels by adjusting the negative feedback regulating calcium

A protein hormone produced by the parathyroid glands in response to a drop in blood calcium ions that will cause an elevation in the calcium

A protein hormone produced by the thyroid gland in response to a rise in blood calcium ions that will decrease in the amount of calcium in the body
