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.
