Skeletal system Flashcards
peristeum
fibrous connective tissue around bones
perichondrium
fibrous connective tissue around cartilage
sesamoid bones
develop in tendons; protect tendons form excessive wear (patella)
facet
smooth, flat area usually covered in cartiglage; where a bone articulates with another bone
fossa
hollow/depressed area
malleolus
rounded process (lateral malleolus of fibula)
trochlea
spool-like articular process that acts as a pulley (trochlea of humerus)
intramembranous ossification
membranous one formation
endochondral ossification
cartilaginous bone formation
mesenchyme
embryonic connective tissue
plane joint
gliding/sliding movements
hinge joint
flex/ext
saddle joint
flex/ext, abd/add, no axial rotation
condyloid joint
flex/ext, abd/add
pivot joint
rotation
Hilton Law
nerves supplying joint also supply muscles moving joint and skin covering distal attachment
Synarthrosis Joint
fibrous joint, united by sutures and syndesmosis
ampiphisial joint
cartilaginous joint, united by hyaline or fibrocartilage
diarthrosis joint
synovial joint,
has 4 characteristics:
cavity, synovial membrane, articular cartilage and fibrous capsule
axial skeleton
head, neck, truck, ribs and sternum
appendicular skeleton
limbs and pelvic girdles
bones develop from
mesenchyme
cartilaginous bone
formed during fetal periods to become bones
endochondral
long bone formation
Metaphysis
between the diaphysis and epiphysis
Hilton’s law
nerves that supply a joint also supply the muscles moving the joint and the skin covering the distal attachments
