TOPIC 6A CONNECTIONS BETWEEN BONES Flashcards
What are immobile joints called
synarthrosis
What are mobile joints called
diarthrosis
What are slightly mobile joints called
amphiarthrosis
types of synarthrosis joints? (2)
fibrous and cartilagenous
types of fibrous joints (4)
gomphysis, sutura, syndesmosis and synostosis
exmaple of syndesmosis joint
eq radius and ulna
whats a syndesmosis joint classified by
interosseus membrane/ligament or fibrous CT uniting bones in the joint
types of suture fibrous joints (4)
Plana, cerrata, foliate, squamosa
example of sutura joint
skull (allows growth in younger animals)
characteristic of gomphosis joint
conical process inserted into socket like portion
example of gomphosis
teeth
2 types of cartilageous joints
synchondrosis and symphysis
whats a synchondrosis joint characterised by, and give example
bones connected by hyaline cartilage - makes the joint immovable and strong eg, first sternocostal joint
whats a symphysis joint, and give example
bones covered by hyalin cartilage and united by fibrocartilage eg. symphysis pelvina
what is common in a diarthrosis joint
a gap between the bones
types of diarthrosis joints
synovial and cartilage
what do incongruent joints have
discus or meniscus or bursa synovial
what is present ina joint
caput and fossa articulare, cavum articulare, capsula articulare of two fused layers (stratum fibrosum and stratum synovial) cartiilago articulare lig articulare (int and ext)
types of simplex joints
monoaxial, biaxial and multiaxial
example of a hinge (ginglymus) joint
art cubiti
example of a pivot (trochoid) joint
atlantoaxial
example of a saddle (sellaris) joint
interphalangeal
example of an ellipsoidal (ellipsoidea) joint
atlantooccipital in ca
example of a plane (plana) joint
intervertebral
example of an amphiarthrosis joint
sacroiliac
4 forms of articular surfaces
condylar (knuckle shaped), sellaris, spheroidal and ellipsoidal
example of a sledge (delabens) joint
femoropatellar
spiral joint?
when collateral ligaments are DISTAL to axis eg stifle in eq
spring/snap joint?
when collateral ligaments are PROXIMAL to axis eg tarsal joint eq
examples of incongruent joint
femorotibial or temporomandibular
