Term
synarthrosis
Definition
little or no movement of joints such as skull sutures, teeth in sockets, etc.
Term
amphiarthrosis
Definition
slightly movable, intervertebral discs, pubic symphysis, etc.
Term
diarthrosis
Definition
freely movable, shoulder elbow, carpal joints, knee, tarsal joints, etc.
Term
fibrous joints
Definition
collagen fibers spanning the space between bones such as skull sutures, teeth in sockets, distal radioulnar joints, etc.
Term
cartilaginous joints
Definition
2 bones bound to each other by cartilage such as intervertebral discs, pubic symph
Term
fibrous joints
Definition
collagen fibers spanning the space between bones such as skull sutures, teeth in sockets, distal radioulnar joints, etc.
Term
cartilaginous joints
Definition
2 bones bound to each other by cartilage such as intervertebral discs, pubic symphysis etc.
Term
synovial joints
Definition
bones held together by joint capsule filled with synovial fluid such as shoulder, elbow, carpal joints, knee, tarsal joints, etc.
Term
suture, gomphosis, synchondrosis, synostosis
Definition
types of synarthrotic joints?
Term
suture synarthrotic joint
Definition
fibrous joint such as adjacent bones in the cranium
Term
gomphosis synarthrotic joint
Definition
fibrous joint such as teeth in sockets of mandible or maxilla
Term
synchondrosis synarthrotic joint
Definition
hyaline cartilaginous joint such as joint between epiphyses and diaphyses
Term
synostosis synarthrotic joints
Definition
occurs when two bones fuse and the joint becomes a bony joint such as when ossification occurs with age between some cranial sutures and epiphyses and diaphyses of the long bones
Term
syndesmosis, synchondrosis, and symphysis
Definition
types of amphiarthrotic joints?
Term
syndesmosis amphiarthrotic joints
Definition
fibrous joint, 2 bones bound by ligament only such as distal radius and ulna or distal tibia and fibula
Term
synchondrosis amphiarthrotic joints
Definition
bones that are bound by hyaline cartilage such as rib attachment to sternum by coastal cartilage
Term
symphysis amphiarthrotic joints
Definition
bones that are joined by fibrocartilage such as pubic symphysis
Term
synovial joint
Definition
joint in which two bones are separated by a space called a joint cavity
Term
diarthrotic joints
Definition
synovial joints that are freely movable
Term
fibrous capsule
Definition
outer part of synovial joint, fused with ligaments
Term
synovial membrane
Definition
inside the joint capsule, secretes synovial fluid
Term
synovial fluid
Definition
lubricates the articular cartilage to reduce friction
Term
synovial cavity
Definition
space inside the joint between two articulating bones
Term
articular cartilage
Definition
hyaline cartilage covering the ends of the bones in the synovial cavity
Term
gliding joint
Definition
allows movement between two plane surfaces
Term
hinge joint
Definition
one bone with convex surface that fits into a concave depression on other bone; change the angle between two bones and allows for angular movement
Term
pivot joint
Definition
one bone has a projection that fits into a ringlike ligament of another; allows for rotational movement between two bones
Term
condyloid joint
Definition
a convex surface that articulates with a concave surface; allows significant movement in two planes
Term
saddle joint
Definition
two concave surfaces that articulate with one another, similar but greater movement than a condyloid joint
Term
ball and socket joint
Definition
smooth hemispherical head fits within a cuplike depression; extensive movement yet less stable (dislocation)
Term
hinge, pivot, ball-and-socket, condyloid, gliding, saddle,
