INTRO TO THE SKELETAL SYSTEM

Bone The dense, semi rigid, porous, calcified connective tissue forming the major portion

of the skeleton of most vertebrates. It consists of a dense organic matrix and an

inorganic, mineral component

BONE FUNCTIONS

Bones are The organs of the skeletal system that

Protect softer tissue Provide muscle attachment points House blood producing cells Store inorganic salts

LONG BONE DESCRIPTION

Have longitudinal axes

Expanded ends (Epiphysis)

Acts as a lever

FLAT BONES (3 DESCRIPTIONS)

Plate like structures

Broad Surfaces

Provides protection

EXAMPLE OF FLAT BONE

The Scapulae Located in the shoulder Serves as a broad plate for anchoring

muscles

IRREGULAR BONE DESCRIPTION

Variety of shapes

Connected to several other bones

Major function is support

EXAMPLE OF IRREGULAR BONE

The Vertebral Column Located in the back Has 33 articulated ring like bones

ROUND BONE DESCRIPTION

Usually small and nodular

Embedded in tendons

Act as pullies

RISK FACTORS OF BONE INJURY

Your older than 65

You’ve broken a bone after age 50

Your close relative has osteoporosis or has broken a bone

Your health is "fair" or "poor"

You smoke

You am underweight for my height
