Q

Loose tissue types

A

areolar, adipose, reticular

19
Q

areolar

A

all three fibers, found under every epithelium, good for strength, support, and elasticity

20
Q

adipose

A

made of adipocytes, fat, looks like large bubbles, supports, protects, insulates,

21
Q

reticular

A

reticular fibers, found in liver, spleen, and lymph nodes, rough out shape of organs

22
Q

Dense connective tissue types

A

dense regular, dense irregular

23
Q

Dense regular

A

collagen, all fibers in straight line

24
Q

dense regular examples

A

tendons, ligaments

25
Q

tendons

A

muscle to bone

26
Q

ligaments

A

bone to bone

27
Q

dense irregular

A

collagen, multiple directions

28
Q

dense irregular examples

A

skin dermis, fascia, heart valves

29
Q

supportive connective tissue

A

cartilage, bone

30
Q

types of cartilage

A

hyaline, fibrocartilage, elastic

31
Q

cartilage made of

A

chondroitin sulfate and fibers, looks like it has a lot of small bubbles (lacunae)

32
Q

hyaline

A

most abundant, made of collagen

33
Q

hyaline function

A

flexible, allows movement at joints

34
Q

hyaline found in

A

embryonic skeleton, ends of long bones, nose and respiratory structures

35
Q

hyaline identification

A

tiny bubbles, looks like no fibers

36
Q

fibrocartilage

A

bundles of collagen

37
Q

fibrocartilage function

A

support, absorb shocks

38
Q

fibrocartilage found in

A

intervertebral discs, menisci of knee, pubic symphysis

39
Q

fibrocartilage identification

A

bubbles, fibers you can see

40
Q

elastic cartilage

A

network of elastic fibers, most rare

41
Q

elastic cartilage function

A

give support, maintain shape, allow flexibility

42
Q

elastic cartilage found in

A

external ear, auditory tubes, epiglottis

43
Q

elastic cartilage identification

A

long black elastic fibers
