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:

1) Epithelial
2) Connective
3) Muscle
4) Neural

Exocrine gland

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

Merocrine Secretion

released from vesicles via exocytosis
Most common
Ex: mucin=mucous, sweat

Apocrine Secretion

involves loss of cytoplasm + secretory product

Holocrine Secretion

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?
