Flashcards in Chapter 2 Deck (55)
Forms the upright part of the body.
Attaches to the axial skeleton and contains bones of the extremities.
Total bones in the body?
Bone is made up of ____ organic material and ___ inorganic material
Gives the bone its elasticity
Gives the bone hardness and strength
Makes up a hard, dense outer shell. Completely covers the bone, tends to be thick along the shaft and thin at the ends of long bones, thick in the plates of the flat bones of the skull
Cancellous bone is also called...
area at each end of a long bone
cartilaginous material in growing bone; longitudinal growth occurs here
main shaft of the bone
hollow; helps decrease weight of the bone. Contains marrow and provides passage for nutrient arteries.
lines the medullary canal, contains osteoclasts.
mainly responsible for bone resorption
Flared part at each end of the diaphysis
Contains nerve and blood vessels that are important in providing nourishment, promoting growth in diameter of immature bone, and repairing the bone.
Attachment point for tendons and ligaments
Two types of epiphyses found in children whose bones are still growing:
pressure epiphysis, traction epiphysis
Located at the end of long bones. Receives pressure from opposing bone making up that joint. This is where the growth of long bones occurs.
Located where tendons attach to bones and are subjected to a pulling, or traction, force. Example: greater and lesser trochanters of the femur and tibial tuberosity
Largest bones in the body
Make up most of the appendicular skeleton
Tend to have more equal dimensions of height, length, and width giving them a cube shape.
Bones of the wrist and ankle
Bones that have a variety of mixed shapes
Resemble the shape of sesame seeds, located where tendons cross the ends of long bones in the extremities
These bones develop within the tendon and protect it from excessive wear.
Broken, cracked bone
Condition characterized by loss of normal bone density or bone mass. Can weaken a bone to the point of fracture
