Study Notes
Functions of Body Membranes
- Cover body surfaces, providing protection and structure
- Line body cavities, creating barriers and compartments
- Form protective sheets around organs, ensuring safety and functionality
- Classified based on tissue types for specific functions
Classification of Body Membranes
- Epithelial membranes
- Cutaneous membranes (skin)
- Mucous membranes
- Serous membranes
- Connective tissue membranes
- Synovial membranes
Epithelial Membranes Overview
- Comprise simple organs, known as covering and lining membranes
- Consist of two layers:
- Epithelial tissue layer for protection and selectivity
- Connective tissue layer providing support and connection
Cutaneous Membrane (Skin)
- Described as a dry membrane, the outermost protective boundary of the body
- Construction:
- Epidermis consists of keratinized stratified squamous epithelium for durability
- Dermis is primarily made of dense (fibrous) connective tissue, providing strength and elasticity
Mucous Membranes (Mucosae)
- Characterized as moist membranes, facilitating various bodily functions
- Line all body cavities that open to the exterior, such as the respiratory and digestive tracts
- Adapted for special functions like absorption or secretion, depending on the location
- Construction includes:
- Variable epithelial tissue types based on the specific site of lining
- Loose connective tissue known as lamina propria, which supports the epithelium
