Study Notes
Neuron Structure and Function
- Dendrites: Receive impulses from other neurons, crucial for signal reception.
- Axon Hillock: Integrates incoming signals from the soma, essential for determining if an impulse should be sent.
- Myelin Sheath: Insulates axons, enhancing the speed and efficiency of signal transmission by preventing loss of electrical charge.
- Terminal Buttons: Release neurotransmitters, key in nerve signal transmission to other neurons or muscles.
- Neurotransmitters: Chemical messengers that facilitate communication between neurons by transmitting impulses across synapses.
- Neuron Transportation: Signals are transported unidirectionally from dendrites through the soma, along the axon, and to the terminal buttons.
- Nodes of Ranvier: Gaps in the myelin sheath that facilitate the rapid movement of ions for impulse generation, crucial for efficient conduction.
- Axon: A long fiber that transmits impulses away from the soma toward other cells, ending in terminal buttons.
- Soma: Contains the nucleus and genetic material, essential for maintaining cellular functions and processes.
