DISTAL END
ARTICULATES WITH TALUS BONE
Occipital Bone
Back of lower head
Osteoblast
immature bone cellderived from osteoprogenitoris a boone establishing cell (lays down the matrix of bone once the matrix is established it entraps inself in a space called a lacuna and converts to osteocyte
ischium
posterior part of pelvic bone
Periosteum
Membrane covering bones, except joint surfaces.
Immovable joints are classified as what?
Synarthrodial
ridge like projection on a bone
crest
DIARTHROSIS
FREELY MOVABLE, SYNOVIAL CAVITY & SYNOVIAL MEMBRANE

MOSTLY APPENDICULAR
transverse fracture
fracture goes straight across bone

ELIPSOIDAL (CONDYLAR)
FLEX, EXTEND, ABDUCTION, ADDUCTION, CIRCUMDUCTION
BETWEEN METACARPALS AND PHALANGES
DISTAL END OF RADIUS AND CARPALS
perichondrium
highly vascularized conn tissue and surrounds the articulating hyaline cart of epiphysisprovides blood supply to avascular hyaline cart.
sesamoid
bones are wrapped in connective tissue, knee cap,,,patella
LINEA ASPERA
POSTERIOR ATTACHMENT PT FOR MUSCLES
Name the class of freely movable joints.
Diarthrodial
Name some short bones.
Carpal, Tarsal, Lunate, Trapezium
Bone marrow
Tissue occupying medullary cavities of long bones and spaces in spongy bone.
Diaphysis
Part of bone formed from primary center of ossification; includes body or shaft
tunnel like opening through a bone usually for blood vessels or nerves
Canal
a long thin thornlike projection or sparp ridge
spine
ARTICULAR CAPSULE
ENCLOSES CAVITY AND BONE ENDS
2 LAYER
-OUTER - FIBROUS, STRENGTH, CONTINUOUS W/ PERIOSTEUM
-INNER- SYNOVIAL MEMBRANE, PRODUCES SYNOVIAL FLUID NOURISHES, LUBRICATES JOINTS
FIBULAR NOTCH
LATERAL ARTICULATION W/ FIBULA AT DISTAL END
Fibula
Smaller bone in lower leg Triangle shaped
osteoclast
derived from wbca bone resorption or break down cell largest bone cell and has multinucleation & vacoules that contain acids and enzymes to break down bone
LATERAL, MEDIAL EPICONDYLES
ATTACHMENT PT FOR MUSCLES

ABOVE DISTAL EPIPHYSIS
List the 2 classes of joints
Functional and Structural
a fixed joint that holds the cranial bones together
suture
comminuted fracture
more than one fracture line,and bones splintered or crushed
WHAT FORMS SPONGY BONE IN EPIPHYSIS
SECONDARY OSSTIFICATION CENTERS
GLIDING (PLANE)
BACK AND FRONT
SIDE TO SIDE WITHOUT ROTARY MOVEMENT
skeletal system mechanical functions:
Framework, proteccts, movement (acts as rigid bar in a lever) sound transduction.
Name some irregular bones.
Vertebrae, Sacrum, Facial bones, Ear bones, Maxilla, Mandible
WHERE IS BONE COLAR DEPOSITED
AROUND SHAFT OF BONE MODEL
Landmark L4, L5
Level of superior aspect of crests of ilia
where is spongy bone found
(epiphyses)ends of long bones and center of other bones
WHICH 2 PLACES DOES INTRAMEMBRANOUS OSSIFICATION OCCUR
SURFACE OF SKULL AND CLAVICLES
WHERE IS ENDOSTEUM LOCATED
LINES MEDULLARY CAVITY IN SHAFT OF LONG BONES
WHERE IS EPIPHYSEAL PLATE LOCATED

BECAUSE IT IS REPLACE AT THE SAME RATE
