macrophages

A

engulfs bacteria and debris

21
Q

plasma cells

A

produce antibodies

22
Q

mast cells

A

mediates inflammatory responses

23
Q

types of connective tissues proper

A

loose (areolar), dense (irregular and regular), elastic, adipose

24
Q

loose (areolar) CT proper composition

A
  • abundant intercellular material
  • few cells
  • few scattered fibers
  • very vascular
  • very flexible
25
Q

loose (areolar) CT proper location

A
  • distributed throughout the body
  • packing material around organs
  • surrounds muscles and blood vessels
  • binds skin to underlying muscle (in a loose way)
26
Q

dense irregular CT proper composition

A

fibers are poorly arranged

27
Q

dense regular CT proper composition

A

fibers are parallel to another

28
Q

dense CT proper location

A
  • ligaments
  • tendons
  • outer covering of the eye
29
Q

elastic CT proper composition

A
  • contains many irregular arranged elastic fibers

- can be easily stretched and returns to original size

30
Q

elastic CT proper location

A
  • walls of arteries

- larynx, trachea, bronchi

31
Q

adipose CT proper composition

A

composed of fat cells filled with lipid

32
Q

adipose CT proper location

A

throughout the body

33
Q

dense CT proper composition

A
  • large number of collagenous fibers packed closely together
  • poor blood supply
  • strong yet flexible
34
Q

cartilage composition

A
  • intercellular matrix (chondroitin sulfate)
  • cells
  • fibers
35
Q

cartilage’s special characteristics

A

- avascular

36
Q

perichondrium

A

tough, outer CT covering

37
Q

avascular

A

receives nutrients by diffusion

38

type of vascular cartilage

A
  • hyaline cartilage
  • fibrocartilage
  • elastic cartilage
39
Q

hyaline cartilage composition

A
  • forms cartilaginous skeleton which serves as a model during fetal development
  • “articular cartilage”- covers the surface/ends of long bones at a joint
40
Q

hyaline cartilage location

A
  • nose
  • trachea
  • bronchi
  • ends of long bones
41
Q

fibrocartilage composition

A
  • contains more fibers
