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
16
Q
Reticular CT
A
-walls of liver, spleen, lymphatic organs
17
Q
Dense CT
A
- bind body parts together
- tendons, ligaments, dermis
- poor blood supply
18
Q
Elastic CT
A
- attachments between vertebra
- walls of large arteries, airways, heart
19
Q
Bone
A
- solid matrix that supports & protects
- forms blood cells
- attachment for muscles
- skeleton
20
Q
Cartilage
A
- rigid matrix
- cartilage cells: chondrocytes in lacunae (spaces where cells are found)
- poor blood supply
- 3 types
21
Q
Blood
A
- fluid matrix called plasma
- red blood cells transport gases
- white blood cells fight infection
- platelets clot
- throughout body in blood vessels
- heart chambers
22
Q
Types of Muscle Tissue
A
Skeletal
Smooth
Cardiac
23
Q
Skeletal
A
- attached to bone
- striated
- voluntary
24
Q
Smooth
A
- walls of organs and blood vessels
- skin
- not striated
- involuntary
25
Cardiac
- heart wall
- involuntary
- striated
- intercalated discs
26
General Characteristics of Muscle Tissue
- muscle cells called muscle fibers
- contractile
- 3 types
27
Nervous Tissue
- found in brain, spinal cord, peripheral nervous
| - basic cells are neurons
28
Most common cell in CT
Fibroblast
29
Phagocytic means...
scavenger, found in macrophages
30
Elastic fibers are found in...
vocal cords & larynx
31

Inner lining of thorax and abdomen and covers organs of thorax and abdomen
32
Where are the mucous membranes found?
Lining of the mouth,nose,throat
33
Where are the cutaneous membranes found?
Covers body&skin
