Ch. 3 - Membranes

Question 1

Membranes (functions)

Answer 1

1. form barriers
2. made of epithelial and CT
3. cover and product

Question 2

Membranes (different types)

Answer 2

Mucous membrane, serous membrane, cutaneous membrane, synovial membrane

Question 3

Mucous membrane

Answer 3

line passageways open to exterior (mainly simple/pseudostratified columnar epithelial)

• contain areolar CT tissue (lamina propria) *provides support for the blood vessels and nerves that supply the epithelium
  ex. respiratory/mouth/digestive and urinary tracts
• form a barrier that resists the entry of pathogens

Question 4

Serous membrane

Answer 4

simple squamous mesothelium supported by areolar CT rich in blood and lymphatic vessels

• secretes watery fluid
  location: lines pleural cavity, abdominopelvic cavity, scrotal cavity, and pericardial cavity

Question 5

Cutaneous membrane

Answer 5

skin
-covers body surface, thick, waterproof, dry, strongest membrane
1-epithelial 2-areolar CT 3-dense irregular CT

Question 6

Synovial Membrane

Answer 6

in synovial (most common/most movable) joints

• produces synovial fluid (reduces friction between the articular cartilage of synovial joints during movement) *lubricates joints
• epithelium, areolar tissue, adipocytes
