Physiology Test #3 Osseus Tissue Flashcards
Intremembranous ossification
Formation of bones within connective tissue
Endochondrial ossification
Formation of bone from a cartilage model
Osteon
Compact bone
Examples of flat bones
Roof of skull
Lower jaw
Clavicle
Clavicle
Collar bone
Simple
Break with bone in skin
Calcium and phosphate
Part of the skeletal mineral reserve
Amphiarthrosis
Slightly movable joint
Lamellae
Sheets of calcified matrix
Osteolysis
Process where osteoclast eats away bone to release calcium
Periosteum
Connective tissue at surface of joints
Gigantism
overproduction of growth hormone
Achondroplasia
reduced epiphyseal plate growth
Osteoporosis
Massive inadequate ossification
Caused many decrease in hormone activity
Pituitary dwarf
All part reduced- puberty offset
Scurvy
Lack of vitamin C
Caused by osteoblasts lapses
Sailors called limies
Osteoblasts
Rebuild skeleton (from bones)
Osteoclasts
Destroy 1/5 of skeleton
Compression
Vertebrae fracture
Comminuted
Shattered into many pieces
Synarthrosis
Immovable joint
Vertebrae
Irregular bone
Humerus
Long bone
Roof of skull
Flat bone
Osteocyte
bone cell
Diaphysis
(Shaft) surrounds the marrow (medullary gland)
Epipyseal
Break on the epiphyseal plate
Epiphysis
(Bone ends) softer point of articulation
Hyperostosis
Overproduction of bone= skeletal deform
External callus
When a break occurs, bone over heals itself creating a large lump on break site
Endosteum
Lines the medullary cavity
Helps in bone growth and repair
Helps in releasing calcium out of body
Spongy
Allows some bone flexibility
Compact
Outer surface of bone (rigid)
Bone
Needs vitamin A, C, D calcium, and phosphate to grow
Suture
Joints between bones of skull
Ossification
Bone formation
short
boxy
covered with compact bone
(bones of wrist and ankle)
compound
break with bone out of skin
diarthrosis
free moving joint
1/5
amount that the skeleton is destroyed each year
femur
long bone (longest bone in body)
long bones
femur
humerus
fingers/toes
forearm/lower leg
patellae
knee cap (sesamoid bone)
spiral
Fractures by twisting (can be from abuse)
Calcium and phosphate
Part of the skeletal mineral reserve
