Connective Tisuse

Question 1

Loose connective tissue or AREOLAR tissue-

Answer 1

Bonds skin to organs, organs to organ, spaces between muscles, throughout body

**most abundant tissue in body

Question 2

Adipose Tissue-

Found?

Function?

Answer 2

Aka fat, beneath skin, around kidneys , eyeballs & abdominal membranes.

Function: protect, insulation to preserve heat & store energy

Cells are called ADIPOCYTES

Question 3

Fibrous connective tissue-

Answer 3

Dense & tightly packed, closely packed, think collagenous fibers & fine network of elastic fibers.

Tendons- connect muscles to bones
Ligaments- connect bones to bone

•few cells, poor blood supply= slow healing

Question 4

what are cartilage cells called?

Answer 4

Chondrocytes

Question 5

Cartilage:
1.
2.
3.
4.
5.
6.

Answer 5

Hyaline cartilage 
Elastic cartilage 
Fibrocartilage 
Bone tissue 
Blood tissue 
Reticuloendothelial

Question 6

Hyaline cartilage-

Answer 6

Very fine white (collagenous) fibers

*most common type

Covers ends of bones, joints, noise, respiratory passages

(Bone growth model)

Question 7

Elastic cartilage-

Answer 7

More flexible elastic

• external ear & larynx (vocal cords)

Question 8

Fibrocartilage-

Answer 8

Larger numerous collagenous fibers.

• Lines in rows
• intervertable disk

Question 9

Bone tissue-

Answer 9

Osseus tissue. Rigid due to layers

Layers- lamellae, Haversian canals, osteocytes
**Looks like tree trucks

Question 10

Blood tissue-

Answer 10

Circulate throughout the body

Transports nutrients oxygen and wastes

Question 11

Reticuloendothelial

Answer 11

Found scattered throughout the body

Immune phagocytes (Destruction of large quantities and toxins/particles)

Question 12

General characteristics:

Answer 12

• Most abundant tissue in the body
• composed of more scattered cells with abundant intercellular material (matrix)
• provide support, protection, framework, fills space, storesstores fat, produces blood cells, fight infection and helps repair tissue
• made up of ground substance (flui, semi-solid and fibers)
• most have a good blood supply
• cells can reproduce (over various time frames)

Question 13

Three common types of cells:

Answer 13

Mast cells: (prevents blood clots) helps blood flow

Macrophages: (phagocytic) scavengers

• kill thing that aren’t supposed to be in matrix
  ex: WBC

Fibroblast: (most abundant, produce, fibers, secrete protein)
- elastic, solid, building blocks of the body

Question 14

Collagenous fibers:

Answer 14

Collagenous fibers- thick, made of protein collagen, major structural protein in the body, appear in long parallel bundles

•hold items together strong but not very elastic also known as white fibers
(Bone, tendons, ligaments)

Question 15

Elastic fibers-

Answer 15

Microfibrils protein and elastin, yellow fibers.
Not as strong but very flexible
(Respiratory and vocal cords)

Question 16

Main types of fibers:

Answer 16

Collagenous fibers

Elastic fibers
