Section 4: Bone Tissue & Bone Growth - Anatomy

Hemopoiesis occurs in:

Red bone marrow (blood cell formation)

Yellow bone marrow function

Fat storage.

Epiphyseal plate function

Lengthwise bone growth

Shaft of a long bone:

Diaphysis

Osteons are found in

Compact bone

Epiphyseal plate location

Metaphysis, between the epiphysis and diaphysis.

Ends of a long bone

Epiphyses

Articular cartilage function

Reduces friction and absorbs shock at joints.

Bedridden person loses bone mass because

Lack of weight-bearing activity and mechanical stress

Teenage growth spurt caused by increased

Growth hormone and sex hormones.

Endosteum:

Membrane lining the internal surfaces of bone, including the medullary cavity.

Collagen secreted by:

Fibroblasts (in connective tissue).

Compound/open fracture

A broken bone associated with a wound that communicates with the outside through the skin.

Made of fibrocartilage:

Intervertebral discs, pubic symphysis, and knee menisci.

Colles' vs. Pott's fracture

Colles' involves the distal radius near the wrist; Pott's involves the ankle

Protein providing bone tensile strength

Collagen

Short bone:

Bone roughly equal in length, width, and thickness

Patellae are examples of:

Sesamoid bones
