Joints Flashcards
Chapter 8
bones that come together at a joint
Articulating Bones
immovable joint classification
Synarthrotic
slightly moveable joint classification
Ampiarthrotic
freely movable joint classification
Diarthrotic
joints held together by dense connective tissue
fibrous joint (suture, syndesmosis, gomphosis)
fibrous joint between flat bones of skull
suture joint
fibrous joint bounds bones with sheets of dense connective tissue or bundles of connective tissue
syndesmosis joint
fibrous joint with cone shaped bony process in a socket in jawbone
gomphosis joint
joints held together with hyaline cartilage or fobrocartialge
cartilaginous joints (synchondrosis, symphysis, synovial)
cartilaginous joint with bands of hyaline cartilage that unite bones
synchondrosis joint
cartilaginous joint with pad of fibrocartilage between bone
symphysis joint
cartilaginous joint with fluid filled cavity
synovial joint
joint of wrist and ankle, nonaxial movement
plane joint
cylindrical surface of one bone articulates with ring of bone and fibrous tissue
pivot joint
convex surface of one bone articulates with concave surface of another
hinge joint
oval-shaped condyle of one bone articulates with elliptical cavity of another
condyloid joint
articulating surfaces have both concave and convex surfaces which articulates in a variety of ways but mainly in two plains
saddle joint
ball-shaped head of one bone articulates with a cup-shaped socket of another bone
ball-and-socket joint
articulating surfaces are nearly flat or slightly curved
gliding
bending at a joint to decrease the angle
flexion
movement increasing the angle between parts of a joint
extension
excess extension, continuing extension beyond anatomical position
hyperextension
moving a part away from midline
abduction
moving a part towards midline
adduction
