Bone What is bone?
Bone What is bone? Made of osseous tissue Major structural and supportive connective tissue Forms rigid part of bones that make up skeleton Mostly made of collagen and calcium Living, growing tissue
Types of Bones Name of Bone Type (yellow) Description of bone structure (blue) Location of Bones (pink) Functions of Bones (green) Sketch an example (white) Flat Bones Long Bones Irregular Bones Sesamoid Bones Short Bones
Flat Bones Thin, roughly parallel surfaces Roof of the skull, sternum, ribs, scapulae Provide protection for the underlying soft tissues and offer extensive surface area for the attachment of skeletal muscles
Long Bones Relatively long and slender Arm, forearm, thigh, leg, palms, soles, fingers, toes Support body weight and facilitate movement
Irregular Bones Complex shapes with short, flat, notched, or ridged surfaces Spinal vertebrae, bones of the pelvis, several skull bones Protection of tissue and providing muscle attachment points
Sesamoid Bones Small, flat, and shaped somewhat like a sesame seed Near the joints of the knees, hands, and feet. Individual people vary in the location and abundance of these. Modify pressure, reduce friction, occasionally alter the direction of muscle pull
Short bones Small and boxy Bones in the wrists Provide support and stability with little to no movement
