what are the 4 shapes of bones?
long, short, flat, irregular
the arms, legs, fingers, toes are an example of this shape of bone?
this type of bone is cubed shape and consist in the wrist, ankle and knee cap as the sesamoid bone
this type of bone is thin, flat, slightly curved and is the sternum, rib, skull bones
this has complicated shapes, vertebrae, and hip bone
what are the 5 functions of bones?
support, protection,movement,mineral storage,hematopoiesis
bones are organs because they contain different tissues name them
this type of bone is dense outer layer
this bone is honeycomb inner layer
spongy bone-spaces are filled with bone marrow
spongy bone is stronger than ____ bone
bone is hard because of
calcium phosphate
this marrow can convert to ____
yellow marrow is fatty and can convert to red marrow in emergencies
we are born with this marrow
this is the shaft of the bone, its medullary cavity is filled with yellow marrow
end of bone, covered with hyaline cartilage
where bones lenghtened before adulthood,replaces the plate
epiphyseal line
double layered membrane, covers surface of bone except at joint surfaces
periosteum-helps anchor blood vessels attached by sharpeys fibers
the inner layer of periosteum consists of _____ what makes bones and _____ which destroys bones
osteoblast, osteocyte
Osteocytes help release this by eating the bone so it can be moved somewhere else in the body if needed
this is a delicate membrane that covers trabeculae(honey comb structure), lines canal of diaphysis, also contains osteoblast and osteocytes
___ is the structural unit of the compact bone
these are classifications of fractures?
position of bones after fracture, completeness of break, orientation of break, skin penetration
this classification of a fracture is non displaced fracture-bones aligned, incomplete fracture-bones out of alignment
postion of bones after break
this classification of fracture is complete fracture-bone broken through, incomplete- broke bone partially
completeness of break
this classification of fracture is linear-parallel to long axis, transverse-perpendicular to long axis
orientation of break
this classification of fracture is open(compound)-penetrates skin, closed(simple)
skin penetration
What are the common fractures?
compression, spiral,epiphyseal,depressed, greenstick
this bone disorder is when the bone is soft, Ca is not deposisted so bones are weak, pain
this bone disorder is bone deform, legs bow,lack of Vit D and or Ca, occurs in children
this bone disorder is bone mass is reduced, bones are porous and light
3 classifications of amount of movement in joints
synarthroses,amphiarthroses, diarthroses
this joint is immovable?
this joint is slightly movable?
this joint is freely movable
what are the structural classification of bones-those that use material to bind bones
the structural classification is immovable, slightly movable
the structural classification is rigid,slightly movable
the structural classification is freely moving
3 types of fibrous joints
sutures-only skull bones, syndesmoses-bones connected by ligament, gomphoses-peg in socket joint
what are the two types of cartilagenous joint?
synchondroses-bone to bone, hyaline cartilage unites them
symphyses-designed to strength, shock, absorp, flex, hyaline is fused to pad of fibrocartilage
this joint is seperated by a fluid filled joint cavity?, allows a lot of movement and has 5 distinguish figures
synovial joints
this type of cartilage deals with synovial joint and is glassy,smooth, absorps compression
this is filled with synovial fluid
joint cavity
the articular capsule covers all joints that are not hyaline cartilage, has two layers this layer is tough, fibrous, dense irregular, strengthens joints, whereas this layer is synovial membrane and consist of loose connective tissue
external, internal
this occupies joint capsule, its viscous(egg white) and decreases as joint warms
synovial fluid
these are bags of lubricant, flattened, lined with synovial mem, provide lubrication and padding,?
bunion is an?
enlarged bursae
an enlongated bursae that wraps completely around a tendon
tendon sheath
