Definition
on the ends of bones, in articular cartilage and developing skeleton
Term
Fibrocartilage is found
Definition
in intervertevral discs, between halves of the pubis, and the menisci
Term
Sutures
Definition
only found binding the flat bones of the cranium
fibrous joints- Sharpey's fibers
synarthrosis- no movement in an adult
Term
Periosteum
Definition
-sense irregular CT surrounding all bones except where articular cartilage is (the joints/ends of long bones)
-has 2 layers: fibrous outer layer and osteogenic inner layer
connected to bone by Sharpey's fibers
Term
Layers of the Periosteum
Definition
-fibrous outer layer that contains fibroblasts
-osteogenic layer that has progenitor cells which develop into osteoblasts (thus growing/widening bone)
Term
Periodontal ligament
Definition
dense regular CT connecting teeth

fibrous joint
Term
syndesmosis
Definition
two joints held together only by a band of ligament (such as the tibia and fibula and the interosseous membrane)
likely to be amphiarthrosis
Term
symphysis
Definition
hyaline cartilage and fibrocartilage
ampiarthroses
located in pubis, ribs, intervetebral discs
Term
synchondroses are located in
Definition
growth plates of long bones, rib 1
Term
