Four Tissue Types

• Epithelia
• Connective
• Muscle
• Nervous

Epithelia

• Cell Shapes
• Squamous
• Cuboidal
• Collumnar

• Arrangement
• Simple
• Stratified
• Pseudostratified

5
Characteristics of Epithelia

• Apical surface
• Basal surface
• Basement membrane
• Avascular
• Highly mitotic
• Minimal neural connections

Endocrine Glands

Exocrine Glands

• Merocrine chemical release salivary glands.
• Apocrine Pinch off portions of cells Mammary
  glands
• Holocrine slough off the whole cell sebaceous
  glands.

17
Connective Tissues

• Contain a matrix
• Some contain fibers
• Have a variety of functional cells
• Most are vascular
• Most have neural connections
