Study Notes
Neuron Structure and Function
- The cell body of a neuron houses the nucleus and cellular machinery essential for life processes, including metabolism and energy production.
- The Greek word "dendron," meaning "tree," refers to the branched appearance of dendrites, which receive signals from other neurons.
- Axons are the parts of neurons responsible for transmitting information away from the cell body to other neurons or muscles.
- The myelin sheath serves as the protective covering around the axon, facilitating faster transmission of nerve impulses through insulation.
- Specialized functions performed by neurons are known as neuron functions or neuronal signaling, which include the processing and transmission of information throughout the nervous system.
