Articulations Flashcards
What are the two types of joints?
functional classification and structural classification
What classification is based on movement?
functional
what classification is based on what they are made of?
structure
What is synarthrosis?
Immoveable joint
what is amphiarthrosis?
slightly moveable
what is diarthrosis?
freely moveable, variety of shapes
what is synotosis?
bone connected to bone by bone
what is fibrous?
held together by fibrous connective tissue, no synovial cavity, has sutures
What is syndesmosis?
bones held together by ligaments
What is gomphosis?
teeth held to jaw by periodontal ligaments
what is cartilaginous
held together by cartilage, no synovial cavity,
Process of sychondrosis
bone held together by hyaline cartilage (epiphyseal)
Process of symphsis
bones held together by fibrocartilage, (pubic symphysis)
Describe synovial
held together by capsule and supporting ligaments, freely moveable
Describe the joint planar/gliding
two flat surfaces slide over each other, (intercarpals)
Describe the hinge joint
convexoxonxave, angular opening and closing motion (elbow, knee)
describe the pivot joint
rounded/ pointed surface of one bone articulates with ring formed partly by a ligament, causes rotation *proximal radioulnar joint)
describe the condlyloid
biaxial with movement, up/down, side to side (your wrist)
describe the saddle
two saddle shapes meet, side by side movement, ( thumb)
describe the ball and socket
ball like surface of one bone fits into cuplike depression (shoulder, hip)q
Describe the movemnt of gliding
flat bone, move back and forth
describe the movement of flexion
bringing in, bring your arms in, bending in
describe the movemnt of extension
bring out, bending arm out
describe hypertension
brees elbow, moving up out of the socket
