Document Summary
Lecture 3: functional neuroanatomy: the nervous system and. Neurons: nerve cells, considered the most important part of the nervous system: commonalities with other cells, mitochondria (energy, cell nucleus (genetic instruction, ribosomes (translates genetic instruction into proteins, three types of neurons, multipolar neurons; most common. Have many dendrites and a single axon: bipolar neurons; common in sensory systems. Have a single dendrite at each end of the cell and a single axon at the other end: unipolar neurons; transmits touch information from body to the spinal cord. Single extension (axon) branches into an input and an output side. Neuron doctrine: the brain is comprised of independent cells and is transmitted cell to cell by synapsis. Golgi stain: fills the whole cell, including the small details. However, only a small portion of the cells will stain (20%). Fluorescent molecule dye can give the same result.
