Topic 8 -Simple organ Membranes

Question 1

Simplest organs tissue types

Answer 1

2 tissue types

Epithelium attached to CT with a basement membrane between them

Question 2

What are the 4 simple organs: membranes

Answer 2

Mucous membranes

Serous membranes

Synovial membranes

Cutaneous membranes

Question 5

Mucous membranes (mucosa)

Answer 5

Line cavities which open directly to the body exterior

Also called the mucosa of the digestive respiratory urinary and reproductive systems

Question 6

What are the two layers of the mucous membranes

Answer 6

Epithelial layer (avascular) varies from simple squamous to pseudostratified

CT layer (loose areolar to vascular) name the lamina propria (only in mucous membranes) nourishes the epithelial cells

Question 7

Serous membranes (serosa)

Answer 7

Lines cavities that do not open to exterior ex abdominal and chest cavities

Covers organs in these cavities

Double membranes each composed of epithelial layers often simple squamous next to serious cavity and CT’s areolar

Question 8

What are the two layers of the serous membranes

Answer 8

Parietal layer -against cavity wall

And visceral layer -against Organ

Serous fluid between layers

Question 9

How are serious membranes named

Answer 9

For location

Pericardium-heart
Pleura -lungs (parietal and visceral pleura)

Peritoneum -abdominal organs

Question 10

Synovial membranes

Answer 10

In joints

Areolar CT, NO epithelium (only one tissue type!)

Question 11

Cutaneous Membranes

Answer 11

Skin

Epithelium is stratified squamous (epidermis)

CT is areolar and dense irregular (dermis)
