|
muscle origin
|
the attachment that is morestable during contraction
usually proximal in limbs |
|
|
muscle insertion
|
the attachment that is more mobile during contraction
(moved by contraction) |
|
|
ligaments
|
connect bone to bone at joints
control/limit movement at joints; resist tension prevent dislocation |
|
|
joint
|
connection between skeletal elements
(bones articulate at joints) |
|
|
tendon
|
connect muscle to bone
bundles of collagen fibers |
|
|
cartilage
|
tough, dense, elastice, compressible connective tissue
|
|
|
synovial joint
|
freely moving joint
|
|
|
hyaline cartilage
|
thin layer of slick articular cartilage
covers the bone |
|
|
joint cavity
|
area between bones in ajoint
space lined by membrane that secretes synovial fluid (lubricant) |
|
|
joint capsule
|
sac of connective tissue attached to articulating bones
encloses the entire joint and confines synovial fluid |
|
|
ball and socket joint
|
aka: spheroidal
very mobile with movement in many directions ex: hip joint |
|
|
hinge joint
|
movement in one plane
ex: knee, elbow |
|
|
saddle-shaped joint
|
aka: sellar
movement in 2 directions ex: thumb |
|
|
cartilaginous joint
(synchondrosis) |
bones united by cartilage
little movement ex: ribs to the sternum |
|
|
symphysis
|
cartilage between bones covered with hyaline cartilage
ex: pubic symphysis |
|
|
fibrous joint
(syndesmosis) |
tight and inflexible
bones united by bands of dense fibrous tissue ex: cranial sutures - fibrous joints of skull (interlocking) |
|
|
synostosis
|
two bones fuse together
|
|
|
compact / cortical bone
|
solid, dense
in walls of bone shafts and on external surfaces |
|
|
subchondral bone
|
compact bone at joints covered by cartilage (smooth, shiny)
|
