Study Notes
Neuron Structure and Functions
- Dendrite: Site where signals are received on a neuron; crucial for input and communication within the nervous system.
- Axon Terminal: Endpoint of a neuron that contains vesicles; crucial for neurotransmitter release into the synapse, facilitating inter-neuronal communication.
- Cell Body: Central part of the neuron housing the nucleus; vital for maintaining the neuron and processing information.
Myelin and Neuronal Support
- Myelin Sheath: Fatty insulating layer around some axons; enhances electrical signal transmission and improves speed of signal propagation.
- Schwann Cell: Specialized cells responsible for producing the myelin sheath around axonal structures; essential for peripheral nerve functionality.
- Node of Ranvier: Small gaps within myelinated axons; critical for saltatory conduction, increasing signal transmission speed.
Genetic and Structural Components
- Nucleus: Dense organelle in eukaryotic cells, surrounded by a double membrane; contains genetic material, essential for cell functions and reproduction.
- Axon: The longest segment of a neuron; conducts electrical impulses from the cell body to the axon terminals, playing a key role in neuron signaling.
