which of the following is a relatively avascular class of connective tissue?
cartilage
Cells that produce cartilage matrix are called __________. Once they become surrounded by matrix and trapped in lacunae, they become _______.
chondroblasts, chondrocytes
chondrocyte
A cartilage that has become enclosed in a lacuna in the catrilage matrix
Primary germ layer function
give rise to all of the body's mature issues
Chondroblast
secrete the matrix and surround themselves with it until they become trapped in little cavaities
blood plasma
-bloods ground substance -the noncellular portion of the blood constituting over 1/2 of its volume -the liquid portion of blood
where would you find spongy bone?
-heads of long bones -forms the middle layer of flat bones (ex. sternum, cranial bones)
where would you find spongy bone?
-in the heads of long bones -within the interior of flat and irregular bones

basal surface
the surface of an epithelial cell that faces the basement membrane
primary function of blood
transport cells and dissolved matter from place to place
