what color does the chondrocyte territoral matrix stain compared to interterritorial matrix?
darker
b/c it has a higher content of GAGS
Label chondrocyte, isogenous groups, interterritorial matrix, territorial matrix, and lacunae in this picture
what is this pointing to in cartilage
perichondrium
how do you change the mechaical properties of cartilage?
by adding other types of fibers. Intermixing elastic fibers produces elastic cartilage, which is easily visualized with the Verhoeff’s elastin stain. It is a more pliable cartilage. Intermixing collagen type I fibers produces fibrocartilage
what kinda of cartlage is this
fetal cartilage
what kind of cartilage is this?
elastic cartilage
Verhoeff stain
what kind of cartilage is this?
fibrocartilage
type I collage is added
label this fibrocartilage
what kind of bone do birds have more of and why?
Birds typically have a much higher percentage of cancellous bone than mammals, as evolution has worked to maximize not just the strength of the bones, but also their strength-to-weight ratio.

spongy bone
what is woven bone formed on top of
a connective tissue matrix
what is this pointing to?
volkman’s canals
how old does this bone look and why
it looks young because the osteons are not dense
periosteum
CT layer surround bone
It is often divided into the outer fibrous periosteum layer (sheet-like CT) and inner cellular periosteum layer (primarily osteocyte precursors
what structure is this pointing to and howw was this slide prepared?
ground section
label this synovial joint
what kind of cartlage is the top arrow pointing to?
articular cartilage
what thing are in a synovial membrane?
within this membrane is type 1 collagen, elastin, 2 kinds of synoviocytes, and it is also rich in sensory nerve fibers
Label the two kinds of cells
