7 Checkpoint (4-1) 1. Define histology. 2. List the four basic types of tissues in the body.
8 B. Epithelial Tissue: includes epithelia and glands 1. Epithelia: layers of cells cover surfaces 2. Gland: secreting cells made of epithelia
9 Characteristics of Epithelial Tissue (4-2) C. Characteristics: 1. Cells bound closely together (cell junctions) 2. exposed to environment, internal chamber, or passageway 3. Attach to connective tissue (basement membrane)
10 4. Lack blood vessels. (Avascularity) 5. Continually replaced (damaged on exposed surface)
11 Epithelial Tissue (4-2) D. Location: 1. Covers body surfaces 2. Lines cavities (around heart and lungs) 3. Lines tubular structures (blood vessels, heart) 4. Serves essential functions (prevent friction, regulate fluid composition internal cavities)
12 E. 4 Functions 1. Provide physical protection 2. Control permeability 3. Provide Sensation 4. Produce specialized secretions A. Exocrine glands: secrete on surface Perspiration, milk from mammary glands B. Endocrine glands: secrete into surround tissue fluid and blood *Hormones
13 F. Intercellular Connections: Epithelial cells must remain attached to basement membrane
14 Intercellular Connections (4-2) (Support and communication Cell adhesion molecules (CAMs) Transmembrane proteins Intercellular cement Proteoglycans
15 Three Common Cell Junctions (4-2) 1. Tight junctions 2. Gap junctions 3. Desmosomes Form bonds with other cells or extracellular material)
16 Figure 4-2a Cell Junctions. Tight junction Adhesion belt Spot desmosome Gap junctions This is a Diagrammatic view of an epithelial cell, showing the major types of Intercellular connections. Hemidesmosome
17 Figure 4-2b Cell Junctions. Interlocking junctional proteins Tight junction Tight junction Adhesion belt Spot desmosome Adhesion belt Gap junctions Hemidesmosome A tight junction is formed by the fusion of the outer layers of two plasma membranes. Tight junctions prevent the diffusion of fluids and solutes between the cells. A continuous adhesion belt deep to the tight junction is tied to the microfilaments of the cytoskeleton.
18 Figure 4-2c Cell Junctions. Tight junction Adhesion belt Spot desmosome Gap junctions Hemidesmosome Embedded proteins (connexons) Gap junctions permit the free diffusion of ions and small molecules between two cells.

98 Glandular Secretion (4-3) (Merocrine secretion Produced in Golgi apparatus Released by vesicles (exocytosis) Example: sweat glands Apocrine secretion Produced in Golgi apparatus Released by shedding cytoplasm Example: mammary glands)
99 Glandular Secretion (4-3) (Holocrine secretion Released by cells bursting, killing gland cells Gland cells replaced by stem cells Example: sebaceous glands)
100 Figure 4-6 Mechanisms of Glandular Secretion. Secretory vesicle Golgi apparatus Nucleus Salivary gland TEM x 3039 Merocrine. In merocrine secretion, the contents of secretory vesicles are discharged at the apical surface of the gland cell by exocytosis. Mammary gland Breaks down Golgi apparatus Secretion Regrowth Hair Sebaceous gland Hair follicle Apocrine. Apocrine secretion involves the loss of apical cytoplasm. Inclusions, secretory vesicles, and other cytoplasmic components are shed in the process. The gland cell then undergoes growth and repair before it releases additional secretions. Cells burst, releasing cytoplasmic contents Cells produce secretion, increasing in size Cell division replaces lost cells Stem cell Holocrine. Holocrine secretion occurs as superficial gland cells burst. Continued secretion involves the replacement of these cells through the mitotic division of underlying stem cells.
