Glandular Epithelium

• Secretion of a product
• goblet cells
• found in PSCC and columnar epithelium
• secrete mucus
• Glands
• endocrine - inside the body
• exocrine - outside the body

9
Connective Tissue

• Keeps other tissues in place
• Protein fibers found in C.T.
• 1. Collagen
• thick - resists stretching (tensile strength)
• Tendons and ligaments, scar tissue
• 10 of humans weight

10
Connective Tissue

• 2. Elastin
• Elasticity and Extensibility
• can stretch and return to original shape
• skin
• 3. Reticulin
• very thin
• not prominent

11
Connective Tissue

• Fig. 4-2 p. 91
• Many types of connective tissue

12
Connective Tissue

• Fibroblast - cell that produces intercellular
  matrix (proteins)
• 1. Loose connective tissue (aka - areolar tissue)
• random protein fibers - collagen and elastin
  mostly
• found between skin muscles and between organs

14
Connective Tissue

• 2. Adipose tissue
• large spherical cells
• protein present - reticulin
• fat storage
• 3. Dense regular connective tissue Proteins are
  organized (parallel)
• tendons and ligaments

Connective Tissue

• 4. Dense irregular connective tissue
• matting of protein (not parallel fibers)
• Dermis - deep layer of skin
• Wrapping around bones and cartilage
• Periosteum or endosteum

Cartilage

• Much harder than other types of connective tissue
  
• protein fibers mixed with ground substance -
  matrix
• chondrocytes - cartilage cells
• found in lacunae
