What are the protective functions of the skin?
-insulates & cushions underlying tissues
- desiccation (prevents H2O loss)
- protects from UV radiation
- regulates heat loss
- protects body from damage (mechanical, thermal & bacterial invasion)
4 Basic types of tissues:
secretes onto the body surface or into a passageway connected to the exterior
-produce exocrine secretions (perspiration on skin, tears in eyes, milk in mammary glands)
Types of Exocrine Glands:
1) Merocrine Secretion
2) Apocrine Secretion
3) Holocrine Secretion
released from vesicles via exocytosis
Ex: mucin=mucous, sweat
involves loss of cytoplasm + secretory product
the entire cell becomes packed with secretory products & then bursts, killing the cell
Characteristics of Epithelial Tissues:
cells are tightly joined
bound surface rests on basement membrane
Functions of Epithelial Tissues:
chemoreception forming linings & coverings
Characteristics of connective Tissue:
manufacture & store substances
highly vascular (except cartilage which is avascular)
not found on free surfaces
often named based on fibers produced & concentration of fibers
What are the fibers in CT?
