30 Cards in this Set

  • Front
  • Back
Slightly Movable Joints
Amphiarthroses
Limbs and girdles
Appendicular Skeleton
Glassy hyaline cartilage covering ephyses; decreases friction
Articular Cartilage
longitudal bones; skull, rib, vertebral column
Axial Skeleton
tiny canals radiating outward from central canals to lacunae
Canaliculi
-slightly movable (amphiarthrotic) pubic symphysis; epiphyseal plates
Cartilaginous Joints
dense, smooth-looking bone;
homogeneous
Compact Bone
Shaft of long bone
diaphysis
Freely Movable joints
diarthroses
thin line of bony tissue in adult bones that looks different; remnant of plate
Epiphyseal Line
flat plate of hyaline cartiliage; causes lengthwise growth of long bones
Epiphyseal Plate
ends of long bones
epiphyses
EX: sutures of skull
syndesmoses(tibia and fibula)
Fibrous Joints
Complex consisting of central canal and matrix ring
Haversian System
(Osteon)
tiny cavities within the matrix
Lacunae
Rings around central canal
Sites of lacunae
Lamellae
cavity of shaft;
yellow marrow (adults)
red marrow (infants)
Medullary Cavity
bone-forming cells
Osteoblasts
Bone-destroying cells
Osteoclasts
mature bone cells
Osteocytes
-horizontal
run into compact bone at right angles to shaft
Perforating (Volkmann's) Canals
formed by two coxal bones
bones are large & heavy
sacrum, coccyx, hip bones
Pelvic Girdle
fibrous connective tissue membrane covering diaphysis
Periosteum
formation of blood cells;
(adults) found in cavity of spony bone of flat bone and epiphyses of long bones
Red Marrow
connective tissue fibers securing periosteum to underlying bone
Sharpey's Fibers (perforating)
clavicle and scapula;
light, allows upper limb to have free movement
Shoulder Girdle
small needelike pices of bones and lots of open space
Spongy bone
immovable joints
Synarthroses
articular cartilage; fibrous articular capsule; joint cavity; reinforcing ligaments (bursae/tendon sheath)
Synovial Joints
adipose (fat) tissue
found in cavity of diaphysis
Yellow Marrow
