Flashcards in Membranes Deck (21):
1

• Physical barriers
• Line or cover portions of the body
• Consist of:
• An epithelium
• Supported by connective tissue

Membranes

2

• Membranes consist of:

• An epithelium
• Supported by connective tissue

3

• Four Types of Membranes

1. Mucous membranes
2. Serous membranes
3. Cutaneous membrane
4. Synovial membranes

4

• Line passageways that have external connections
• Epithelial surfaces must be moist
• ---To reduce friction
• ---To facilitate absorption and excretion
• Lamina propria
• ---Is areolar tissue

• Mucous Membranes (Mucosae)

5

• In digestive, respiratory, urinary, and reproductive
tracts

• Mucous Membranes (Mucosae)

6

Why must Epithelial surfaces be moist?

• ---To reduce friction
• ---To facilitate absorption and excretion

7

Is areolar tissue

Lamina propria

8

are coated with the
secretions of mucous glands.

Mucous membranes

9

membranes line the digestive, respiratory,
urinary, and reproductive tracts

Mucous membranes

10

• Line cavities not open to the outside
• Are thin but strong
• Have fluid transudate to reduce friction
• Have a parietal portion covering the cavity
• Have a visceral portion (serosa) covering the organs

• Serous Membranes

11

visceral portion of • Serous Membranes is also known as ______, which covers the organs

serosa

12

• Three Serous Membranes:

1. Pleura
• Lines pleural cavities
• Covers lungs
2. Peritoneum
• Lines peritoneal cavity
• Covers abdominal organs
3. Pericardium
• Lines pericardial cavity
• Covers heart

13

• Lines pleural cavities
• Covers lungs

1. Pleura

14

• Lines peritoneal cavity
• Covers abdominal organs

2. Peritoneum

15

• Lines pericardial cavity
• Covers heart

3. Pericardium

16

line the ventral body
cavities (the peritoneal, pleural, and
pericardial cavities).

Serous membranes

17

• Is skin, surface of the body
• Thick, waterproof, and dry

Cutaneous Membrane

18

• Line moving, articulating joint cavities
• Produce synovial fluid (lubricant)
• Protect the ends of bones
• Lack a true epithelium

• Synovial Membranes

19

Acts as a lubricant for membranes

synovial fluid (found in synovial membranes)

20

covers the
outer surface of the body.

cutaneous membrane or most commonly referred to as the skin

21

line joint cavities and produce
the fluid within the joint.

Synovial membranes
