1. Excitability: Nerve cells are able to respond to various stimuli, such as chemical signals or electrical impulses, by generating electrical signals known as action potentials.
2. Conductivity: Nerve cells are able to transmit these electrical signals over long distances through their long, thin projections called axons.
3. Connectivity: Nerve cells are interconnected with other nerve cells through specialized junctions called synapses, allowing for communication and coordination of signals within the nervous system.
4. Plasticity: Nerve cells are capable of changing and adapting their structure and function in response to experience, learning, and injury.
5. Longevity: Nerve cells are typically long-lived cells that can survive for the entire lifespan of an organism.
6. Specialization: Nerve cells are highly specialized for their function in transmitting and processing information within the nervous system, with different types of nerve cells performing specific roles in signal transmission, processing, and integration.

Key Characteristics of Nerve Cells (Neurons):
1. Structural Specialization:
- Cell Body (Soma): Contains the nucleus and other primary organelles.
- Dendrites: Short, branched extensions that receive signals from other neurons.
- Axon: A long, thin projection that transmits signals away from the cell body.
- Axon Terminal (Synapse): Terminal structure of the axon that forms connections with other neurons.
2. Electrical Excitability:
- Possess ion channels in their membrane that allow for the movement of ions.
- Capable of generating electrical signals called action potentials that travel along the axon.
3. Chemical Signal Transmission:
- Release neurotransmitters at synapses that bind to receptors on target cells.
- Neurotransmitters can excite or inhibit the activity of target cells.
4. Polarized Membranes:
- Maintain a resting membrane potential (voltage difference) across their membrane.
- This polarization allows for the generation of action potentials.
5. Insulation:
- Myelin Sheath (in some axons): A fatty layer that insulates the axon and speeds up signal transmission.
6. Synaptic Connections:
- Form synapses with other neurons or cells to transmit signals.
- Synapses can be excitatory (stimulating) or inhibitory (dampening).
7. Complexity and Diversity:
- Exist in a vast array of shapes and sizes.
- Perform diverse functions, including sensory, motor, cognitive, and memory processing.
8. Plasticity:
- Capable of changing their structure and function over time in response to experience.
- This plasticity underlies learning and memory.
9. Regeneration Potential (limited):
- Neurons can regenerate some axons and dendrites, but not the entire cell body, after injury.
