the condition for being within the parameters of optimal functions within a body

negative feedback loop

Referring to control systems, a type of feedback mechanism that produces an action opposite to the change that activates the system.

a chemical that reduces the activation energy required to start a chemical reaction.

Present in cartilage, the cells responsible for producing fibers and tough, rubbery ground substance in cartilage.

Superficial layer of skin consisting of five layers or strata. Stratum Basale, Stratum Spinosum, Stratum Granulosum, Stratum Lucidum, and Stratum Corneum.

the extracellular matrix of bone, subdivided into two components, inorganic salts and organic matrix. Two thirds is composed dry inorganic salts while one third is organic material.

Red blood cell formation occurring in red bone marrow.

endochondral ossification

Cartilage turns into bone tissue as bone formation starts from the center of diaphysis to the epiphyses. Cartilage model is formed and then turned into bone.

Layer of cartilage that separates the epiphyses from the diaphysis in early bone development. Becomes replaced with bone and is called the epiphyseal line or metaphysis.

Bones of the skull, vertebral column, and ribs.

appendicular skeleton

Upper and lower extremities, or appendages. Bones of the arms, hands, legs and feet.

Supports the trunk and attaches lower extremities. Coxal bones and sacrum.
