Study Notes
Neuron Overview
- A neuron is a nerve cell responsible for carrying impulses throughout the body, facilitating communication within the nervous system.
Dendrites
- Dendrites are short, branching fibers extending from the neuron’s cell body that receive incoming signals and messages from other neurons.
Nucleus
- The nucleus is a vital part of the neuron cell, containing DNA and RNA. It plays a crucial role in the growth and reproduction of the neuron.
Axon
- The axon is a long nerve fiber that transmits electrical impulses away from the neuron's cell body to other neurons, muscles, or glands.
Axon Terminals
- Axon terminals are the branching ends of axons, allowing for the connection and transmission of signals to adjacent cells.
Soma Cell (Cell Body)
- The soma, or cell body, contains the nucleus and integrates incoming signals before passing them along the axon. It is essential for maintaining the cell's functions.
Myelin Sheath
- The myelin sheath is a protective layer of fatty tissue that encases the axon, enhancing the speed of nerve impulse transmission and improving communication efficiency within the nervous system.
