Question 6

What are the three types of germ layer cells

Answer 6

Mesoderm, ectoderm and endoderm

Question 7

Middle layer of a germ cell that differentiates into connective tissue, bones and muscle tissue

Question 8

What is the ectoderm

Answer 8

The outer layer of a germ cell that differentiates into nervous tissue and skin cells

Question 9

What is the endoderm

Answer 9

inner layer of germ cells that differentiate into the lining of the digestive tissue and organs

Question 10

Answer 11

Mesoderm

Question 12

Which type germ cell differentiates into Nervous tissue

Answer 12

Ectoderm

Question 13

Which type germ cell differentiates into Epithelial

Answer 13

Mesoderm, ectoderm and endoderm

Question 14

What are the 4 types of shapes cells come in

Answer 14

Squamous, columnar, cuboidal and transitional

Question 15

Where are simple squamous cells found

Answer 15

In the alveoli and capillaries of the lungs. Squamous cells are flat so have a small diffusion distance.

Question 16

Where are simple cuboidal cells found

Answer 16

Kidney tubule

Question 17

Where are simple columnar found

Answer 17

Small intestines

Question 18

Where are transitional cells found

Answer 18

In the urinary tract

Question 19

Where are stratified squamous cells found

Answer 19

oesophagus

Question 20

Where are keratinised stratified squamous cells found

Answer 20

In the skin

Question 21

Where are pseudostraified cells found

Answer 21

Trachea and nasal mucosa

Question 22

Where are transitional cells found

Answer 22

Only in the urinary tract as it stretches to accommodate for increasing fluid.

Question 23

What is the apical and basement surface of the epithelial cells

Answer 23

The top of the epithelial cell = apical
The bottom of the epithelial cell = basement

Question 24

What lies on the apical surface

Answer 24

Microvilli and cilia

Question 25

What are the four epithelial membranes

Answer 25

Serous, mucous, cutaneous and synovial

Question 26

What is the serous membrane

Answer 26

Epithelia that is found in closed cavities.

Question 27

What is the pleura

Answer 27

Serous membrane in the lungs

Question 28

What is the pericardium

Answer 28

Serous membrane lining the heart

Question 29

What is peritoneum

Answer 29

Serous membrane lining the abdominal organs 5

Question 30

What is the parietal layer

Answer 30

The outer membrane of the serous membranes that attaches to the body wall around the organ

Question 31

What is the visceral membrane

Answer 31

The inner membrane of the serous membranes that is attached to the organ itself

Question 32

What is the mucosa membrane

Answer 32

Epithelia that lines cavities open to the outside which produce mucus. Found in respiratory tract

Question 33

What is Cutaneous membrane

Answer 33

Epithelia which lines the surface of the body (skin) it is keratinised squamous

Question 34

What is synovial membrane

Answer 34

Epithelia which lines freely movable joints.
