Tissues

Question 1

Four Primary Tissue Types (CMEN)

Answer 1

Epithelial
Connective
Muscular
Nervous

Question 2

Epithelial Tissue Function:

Answer 2

protection, secretion, filtration, absorption, sensory e.g. skin
covers all surfaces of the body and lines inside of organs. provides body’s first line of protection form phsyical, chemical, and biological wear and tear.

Question 3

Muscular Tissue Function:

Answer 3

Provides movement, maintains posture, produces heat.

e.g. smooth, skeletal, cardiac

Question 4

Nervous Tissue Function

Answer 4

responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.

Question 5

Connective Tissue Function

Answer 5

• connects, structure, support, protection, highly vascularised and has nerve supply.
• high tensile strength
  e. g. tendon

Question 6

Four Types of Connective Tissue

Answer 6

• proper
• cartilage
• bone
• blood

Question 7

three fibres in Connective Tissue:

Answer 7

• collagenous (thick, high tensile strength)
• elastic (long, thin, stretch)
• reticular (short, fine, branch out)

Question 8

Two types of proper connective tissue:

Answer 8

1. Dense: is for strength (irregular, regular, elastic)

2. Loose: holds organs in place (adipose, areolar, reticular)

Question 9

Cartilage

Answer 9

type of connective tissue that forms structural components of body

Question 10

three types of cartilage:

Answer 10

1. Hyaline
2. Elastic
3. Fibrocartilage

Question 11

Hyaline Cartilage

Answer 11

form on joints of long bones

Question 12

Elastic Cartilage

Answer 12

provides strength, and elasticity while mantaining shape. e.g. nose, ear epiglottis

Question 13

Fibrocartilage

Answer 13

strongest cartilage.

Question 14

Bone:

Answer 14

major structural and supportive connective tissue. responsible for ridgity, slight flexibility, maintainance of calcium, blood cell production.

Question 15

Blood:

Answer 15

transports H2O and CO. connects body systems together, brings oxygen, nurtients, hormones etc and removes wastes

Question 16

Simple epithelial

Answer 16

one layer

Question 17

Stratified epithelial

Answer 17

more than one layer

Question 18

Psuedo-stratified epithelial

Answer 18

one layer, but looks like more than one

Question 19

Squamous Epithelial Cells

Answer 19

flat cells

Question 20

Cuboidal Epithelial Cells

Answer 20

Cube like shaped cells

Question 21

Columnar

Answer 21

collum like shaped cells

Question 22

Glandular Epithelium

Answer 22

a gland is a single or a mass of epithelial cells adapted for secretion

Question 23

Keratinised Epithelial Cells

Answer 23

numerous layers of dead squamous cells, which are specially structured to be waterproof and reduce evaporation from underlying tissues. e.g. epidermis

Question 24

Non-Keratinised Epithelial Cells

Answer 24

moist, and it contains living cells in the surface layer. e.g. lips

Question 25

Non-cilliated Epithelial Cells

Answer 25

Nonciliated cells lack cilia and goblet cells

Question 26

Ciliated Epithelial Cells

Answer 26

secrete mucus and bear cilia

Question 27

Types of Connective Tissue

Answer 27

``` Proper Connective Tissue: - Loose: holds organs in place - Dense: strength 'Lara was in Dire straights' Other Connective Tissue: - Cartiliage - Bone - Blood ```

Question 28

Loose Connective Tissue | L-ARA

Answer 28

- Areolar: in skin, mesh like - Adipose: store fat (lipids) molecules, lines organs for protection - Reticular: in lymph nodes

Question 29

Dense Connective Tissue (D-IRE)

Answer 29

Regular: e.g. tendons, ligaments Irregular: e.g. dermis Elastic: e.g. in blood vessels

Question 30

Cartilage

Answer 30

- firm but softer than bone - made up of chondrocytes - no blood vessels

Question 31

Types of Cartilage

Answer 31

- Hyaline/Articular Cartliage: lines the portion where two bone meet - Elastic: provides strength, elasticity, maintians shape e.g. epiglottis - Fibrocartilage: found in weight bearing joints

Question 32

Bone:

Answer 32

- highly vascular and mineralised - major structural and supportive tissue - responsible for rigidity and slight flexibility - maintenance of calcium stores primary location of blood cell production

Question 33

three types of cells in bones:

Answer 33

- Osteoblasts: deposit bone - Osteocytes: maintain bone - Osteoclasts: break down bone

Question 34

Blood

Answer 34

- fluid connective tissue - comprised of formed elements surrounded by a liquid matrix containing dissolved substances - Erythrocytes (RBC): distributes oxygen - Leukocytes (WBC): immune response - Platelets: blood clotting
