Chapter 5 Tissues Pt2 Flashcards
1
Q
Characteristics of Connective Tissue
A
- most abundant type in body
- binds structures
- provides support and protection
- framework
- Fills spaces
- stores fat
- produces blood cells
- protects against infection
- helps repair tissue damage
2
Q
Types of Cartilage
A
Hyaline
Elastic
Fibro
3
Q
Hyaline
A
- most abundant
- ends of bones
- nose, respiratory passages
- embryonic skeleton
4
Q
Elastic
A
- flexible
- external ear, larynx (voicebox)
5
Q
Fibro
A
-very tough
-shock absorber
-intervertebral discs
cushions knee &pelvic girdle
6
Q
Types of CT Cells
A
Fibroblast
Macrophages
Mast Cell
7
Q
Fibroblast
A
- fixed cell
- large, star shaped
- produces fibers (secretes protein)
8
Q
Macrophages
A
- wondering cells
- phacocytic (scavenger aka PACMAN)
- important in defense and immunity
- originate as WBC
9
Q
Mast Cells
A
- fixed cells
- usually near blood vessels
- release heparin (clotting substance)
- release histamine(promotes reactions to inflammation&Allergies
10
Q
Types of CT Fibers
A
Collagenous
Elastic
11
Q
Collagenous Fibers
A
- thick threads of collagen
- great tensile strength
- abundance in dense CT
- holds structures together
- tendons,ligaments
12
Q
Elastic Fibers
A
- bundles of microfibers embedded in elastin
- fibers branch
- elastic
- vocal cords, air passages
- not as strong but very elastic
13
Q
Categories of CT
A
Proper( Loose CT, Adipose T, Reticular CT, dense CT, Elastic CT)
Specialized( Cartilage, Bone, Blood)
14
Q
Loose CT
A
- made of fribroblasts
- elastic fibers
- binds skin to structures
- found beneath most epithelia
- between muscles
15
Q
Adipose T
A
- adipocytes( forms adipose tissue when crowds out other cell types)
- cushions, insulates, stores fat
- born with certain number of fat cells, excess calories are converted to fat &stored
