HLSC 2400U Chapter Notes - Chapter 2 : Chemical Synapse, Purkinje Fibers, Golgi Apparatus
Document Summary
Lecture #3 physical and electrical properties of cells in the nervous system. The soma is the protein generating structure since the nucleus, golgi apparatus, and rough. Axon is the output unit of the cell, sends information to other neurons, muscle cells, and glands. (transmission) Presynaptic terminals transmit a signal to another cell, neurotransmitter (transfer of information) Synaptic cleft interaction of one neuron to another neuron, presynaptic neuron releasing neurotransmitter into synaptic cleft, interact to postsynaptic nerve or dendrites of the receiving neuron. Mechanism neurons use for transporting substances along the axon. Protein being created is neurotransmitter, need to be released by presynaptic terminal. Anterograde cell body to the presynaptic terminal. Retrograde synapse back to the soma: once the neurotransmitter is used, it can"t be used again, has to be repackaged and up through retrograde to be broken down and used again. Cells are classified based on the number of structures.
