Which of the following is NOT one of the fundamental properties of neurons?

The fundamental properties of neurons include conductivity, excitability, and secretion. These properties are essential for the function of the nervous system.

Conductivity refers to the ability of neurons to transmit electrical impulses along their axons to communicate with other neurons, muscles, or glands. This is crucial for transmitting signals throughout the nervous system.

Excitability describes a neuron’s capacity to respond to stimuli by generating action potentials. This property allows neurons to react to various signals, whether from the environment or other cells, and is fundamental to their role in sending and processing information.

Secretion involves the release of neurotransmitters from the axon terminals of neurons. This process is vital for communication between neurons and other types of cells, enabling the transmission of signals across synapses.

In contrast, regeneration is not considered a fundamental property of neurons. While some neurons exhibit limited capacity for regeneration, especially in the peripheral nervous system, many neurons in the central nervous system do not regenerate effectively after injury. This limitation sets regeneration apart from the other key properties that define how neurons operate in both health and disease.
