Study Notes
Body Membranes
- Body membranes cover body surfaces, line body cavities, and form protective sheets around organs.
- Classified according to tissue types.
Classification of Body Membranes
- Epithelial membranes
- Cutaneous membranes
- Mucous membranes
- Serous membranes
- Connective tissue membranes
- Synovial membranes
Cutaneous Membrane
- Also known as skin
- Outermost protective boundary
- Superficial epidermis composed of keratinized stratified squamous epithelium
- Underlying dermis is mostly dense connective tissue
- Covers the body surface
Mucous Membranes
- Surface epithelium type depends on site
- Lines all body cavities that open to the exterior body surface
- Often adapted for absorption or secretion
- Examples: mucosa of nasal cavity, mouth, esophagus, and lung bronchi
Serous Membranes
- Surface is a layer of simple squamous epithelium
- Underlying layer is a thin layer of areolar connective tissue
- Lines open body cavities that are closed to the exterior of the body
- Occur in pairs separated by serous fluid
- Visceral layer covers the outside of the organ
- Parietal layer lines a portion of the wall of ventral body cavity
- Examples: peritoneum, pleura, and pericardium
Connective Tissue Membrane
- Synovial membrane
- Connective tissue only
- Lines fibrous capsules surrounding joints
- Secretes a lubricating fluid
Integumentary System
- Skin (cutaneous membrane)
- Skin derivatives: sweat glands, oil glands, hair, and nails
Skin Functions
- Protects deeper tissues from mechanical damage, chemical damage, bacterial damage, ultraviolet radiation, thermal damage, and desiccation
- Aids in body heat loss or heat retention as controlled by the nervous system
- Aids in excretion of urea and uric acid
- Synthesizes vitamin D
Skin Structure
- Epidermis: outer layer, stratified squamous epithelium, cornified or keratinized, avascular, most cells are keratinocytes
- Dermis: dense connective tissue
- Hypodermis (superficial fascia): deep to dermis, anchors skin to underlying organs, composed mostly of adipose tissue
