Articular cartilage Smooth, slippery, and bloodless. Remaining evidence of an adults bones
cartilaginous past.
Periosteum Fibrous, cellular, vascular, and highly sensitive life support sheath of bone.
Provides nutrient blood for bone cells and a source of bone-developing cells during growth
after fracture. Doesn't cover articular cartilage
Cancellous (Spongy) Bone -Tiny beams of bone forming a latticed truss capable of
reorientation
-Resists the stresses of weight and postural changes as well as muscular development
Red Marrow Packs the spaces between beams of certain bony epiphyses and elsewhere. It
consists of masses of developing and mature red/white blood cells supported by an array of
loose, fine fibers.
Compact Bone The dense bone of the diaphysis, compact bone consists of repeating
patterns of solid bone tissue organized into concentric layers. Nutrient blood reaches the bone
cells by a system of integrated canals.
Nutrient Artery Each long bone contains an oblique tunnel in its shaft which enters the
medullary cavity and branches throughout, supplying the shaft. Arteries to the epiphyses
generally arise from the joint capsule
Medullary Cavity In the diaphysis serves to lighten bone weight and provides space for its
marrow
, Yellow Marrow Has some red cells and has some white blood cells, but its color is due
mostly to its having more fat cells
Fibrous Joints A joint that is held together by fibrous tissue including collagen fibers
Cartilage Joints (slightly movable) Bones held together by cartilage
Synovial Joints (freely movable) Joints that include synovial cavity which contains a fluid
secreted by the synovial membrane
Joint Where 2 or more bones articulate
Function of Appendicular skeleton movement/locomotion
Function of Axial Skeleton -Protect organs & brain
- It also provides sites for the attachment of other bones and muscles
-
What are the 4 types of bones long, flat, short, irregular
Cartilage -Connects bones together
-Do not contain blood vessels, thus it takes longer to repair than other tissues
3 TYPES
Hyaline Cartilage- in the joints, the respiratory tract, and the immature skeleton EX. Noes
