Unformatted text preview: The Brain Neuron (Nerve Cells) Specialized to receive and transmit messages Everything your body does depends on neurons Feelings, emotions, thoughts, movements, EVERYTHING 100-200 billion in the brain alone Similar to other organelles in the body Nucleus Contains genetic material (chromosomes) including information for cell development and synthesis of proteins necessary for cell maintenance and survival. Covered by a membrane. Nucleolus Produces ribosomes necessary for translation of genetic information into proteins Nissl Bodies Groups of ribosomes used for protein synthesis. Endoplasmic reticulum (ER) System of tubes for transport of materials within cytoplasm. Can have ribosomes (rough ER) or no ribosomes (smooth ER). With ribosomes, the ER is important for protein synthesis. Golgi Apparatus Membrane-bound structure important in packaging peptides and proteins (including neurotransmitters) into vesicles. Microfilaments/Neurotubules System of transport for materials within a neuron and may be used for structural support....
