BIOMED 10/22a CT Histology Lab Flashcards
what kind of tissue is seen around blood vessels?
loose CT
-increased ground substance and space for things to travel
what type of fibers comprise dense regular CT?
type I collagen
bundled in a parallel arrangement
what is the purpose of the arrangement of parallel collagen fibers in dense regular CT?
allows for increased tensile strength
where do you see dense regular CT
tendon
ligaments
aponeurosis
fascia
what is the purpose of fibroblasts in dense regular CT?
- Function: produce ground substance and various different fibers
- Arrangement promotes: communication
how do you differentiate between type I and type II collagen?
type I is arranged in parallel, type II is not as orderly
what does the fiber arrangement of type II collagen tell you?
it allows its shape to be changed based on compressive stress and allows for recoil
where is type II collagen found?
ligaments and hyaline and elastic cartilage
how do you know what dense irregular connective tissue looks like?
cooked fettuccine in red sauce
what is dense irregular CT packed with?
collagen and elastic fibers(not readily seen)
what kind of forces does dense irregular CT take?
able to withstand forces in multiple directions
where is dense irregular CT found?
dermis of skin, bursae, sheaths around tendons
what does Loose CT look like?
it has big bubbles aka adipose in it and a lot of lymphocytes
what characteristics in loose CT help you ID the CT type?
Sparse fibers, increased cells and ground substance, adipose tissue, and blood vessels
what type of collagen can readily be seen in loose CT?
type II collagen
