ANAT.3601

• Cell Membrane
• Nucleus
• Endoplasmic Reticulum SER/RER
• Golgi Apparatus
• Mitochondria
• Cytoskeleton
• Cell Surface structures
• Endoplasmic structures

• Protects the cell
• Mediates nutrition/secretion
• Communication to cells and their environment
• Eliminates waste products

*All constructed as lipid bi-layers.

• Transport material to/from interior.
• DNA, RNA
• Protein synthesis
• Control center of the cell

SER: Synthesizes lipids, metabolize carbs, detoxifies drugs/alcohol.

RER: Synthesize proteins, transports and stores molecules.

Modifies, packages, and sorts newly synthesized proteins for secretion, inclusion in new plasma membrane, or lysosomal enzyme synthesis.

• "Powerhouse of cell"
• ATP production
• Lipid metabolism (w/ SER)

• Provides structural support
• Organelle and cellular motility
• Transport of materials
• Mitosis

• Cytoskeletal elements
• 1) Microtubules
• 2) Microfilaments (Actin)
• 3) Intermediate Filaments

• 1. Microvilli increase surface area and cell surfaces.
• (AKA: Brush Borders or Striate Borders)

2. Cilia move material along the surface of cells.

3. Junctional complexes link cells together.
