2 Types of Membranes in our Bodies 1. Epithelial Membranes 1.Cutaneous 2.Mucous membranes (mucosa) 3.Serous (serosa) 2. Connective Tissue Membrane 1.Synovial Membrane
Slide 4.3 Epithelial membranes 1. Cutaneous Membrane ( 1. Cutaneous Membrane (AKA Skin) “dry” – exposed to air stratified squamous epithelium & dense fibrous connective tissue protection, maintains boundaries, synthesize Vit D, Insulates, nerve receptors Stratified squamous Dense fibrous
Slide 4.4 Epithelial Membranes 2. Mucous Membranes (mucosa) Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Epithelium & loose connective tissue underneath absorption or secretion open to the exterior lines all organs that open to the exterior (respiratory & digestive system) Figure 4.1b
Slide 4.5 Epithelial membranes 3. Serous Membranes (serosa) Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings simple squamous epithelium & loose connective tissue surrounds body organs (closed to exterior) Composed of 2 layers separated by fluid Figure 4.1c
Serous Membranes (Cont.) Come in paired layers (serous fluid between layers) – Parietal: layer lines the cavity – Serous Fluid (between layers) – clear fluid – Visceral: layer lines the organ (viscera) – Named by location (see next slide)
Slide 4.6 Examples of Serous Membranes Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Peritoneal cavity Peritoneum Pleura Pericardium
Slide 4.7 Connective Tissue Membrane Synovial Membrane Copyright © 2003 Pearson Education, Inc. publishing as Benjamin Cummings Dense Fibrous connective tissue lines capsules surrounding joints Lubricates joint Bursae- sacs under ligaments - cushion Figure 4.2 bursae

Chapter 4: Skin and Body Membranes
Skin and Body Membranes – Part 1
Classifications of Body Membranes Connective tissue membranes –synovial Epithelial membranes –mucous or mucosa –serous or serosa –cutaneous.

Three general Membranes!
Skin and Body Membranes. Function of body membranes – Line or cover body surfaces – Protect body surfaces – Lubricate body surfaces.
These cover surfaces, line body cavities, and form protective sheets around organs Two main types: ◦ Epithelial membranes (cutaneous, mucous, and serous.
Epithelial Membranes Epithelial sheets bound to and underlying layer of the connective tissue proper Types Cutaneous ○ Epithelial & connective tissue.

HCT I. Membrane- A thin sheetlike structure covering and protecting the body surface, line body coavities and cover inner surfaces of the hollow organs.
Introduction to the Integumentary System Chapter 4 Vocabulary Part of the body where it’s found.
Body Planes Anatomic reference systems describe the location and functions of body parts. The basic reference systems are: body planes, body directions,
