Cell Structure

Cell Structure

1. Type of Cell

   • Muscle
     • Neuron
       • Motor Neuron
       • Unipolar
       • Bipolar
     • Striated
     • Smooth
     • Cardiac
   • Bone
     • Epitheleal
       • columnar
       • Cuboid
       • Squamous
     • Osteoblast (Builds bone)
     • Osteoclast (break down bone)

2. Cell Organelles

   • Organelles
     • Endoplasmic Reticulum
       • RER: Rough Endoplasmic Reticulum
         • 1. membranes in Cell Attached to Ribosomes 2. Factory of Cell, Where proteins are Made
       • SER: Smooth Endoplasmic Reticulum
         • 1. No Ribosomes. 2. Where lipid membrane formed
     • Golgi Packaging/Shipping
       • Materials Enclosed in Vessicles and labelled with appropriate makers
     • Lysomes (Recycling)
       • Hydrolytic enzymes digest Cell parts and englufed materials
     • Endosomes
       • Truck Drivers: Bring Materials to surface/ other organelles
     • Microtubules and Microfibrils
       • Bus Drivers: Transport systems to and from releases Sites in Cell
     • Peroxisomes( Break down)
       • Breakdown with Hydrogen peroxide
         • Prevalent in kidney/Liver cells because detoxifying. To much detoxifying can lead to breakdown in cells containing peroxisomes -> Cirrhosis of liver in Alcoholics

3. Membranes

   • Membrane Organisation
