Study Notes
Neuron Overview
- Neurons are specialized nerve cells responsible for transmitting impulses throughout the body.
Dendrites
- Short, branching fibers that extend from the neuron’s cell body.
- They are responsible for receiving incoming messages and signals from other neurons.
Nucleus
- Found within the neuron; contains DNA and RNA.
- Plays a critical role in the growth and reproduction of the neuron.
Axon
- A long nerve fiber that carries impulses away from the neuron's cell body.
- Essential for sending signals to other neurons or muscles.
Axon Terminals
- The branching ends of axons that connect neurons to other cells.
- Critical for neurotransmitter release, facilitating communication between neurons.
Soma (Cell Body)
- Contains the nucleus and integrates incoming signals from dendrites.
- Sometimes referred to as the soma; essential for maintaining the neuron's health.
Myelin Sheath
- A fatty layer that encases the axon of a neuron, acting like insulation.
- Increases the speed of impulse transmission along the axon.
Schwann Cells
- Specialized cells that form the myelin sheath around nerve fibers in the peripheral nervous system.
- Crucial for the protection and efficiency of nerve signal transmission.
