An interaction with the world.
The first response a neuron makes to a stimulus is called depolarization. This is when the neuron's electrical charge changes, allowing it to transmit an electrical signal down its length to communicate with other neurons.
A neuron conveys information about the strength of stimuli by varying the rate in which the stimulus is fired.
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.

The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.

False( When a stimulus acts on a neuron, it increases the permeability of the stimulated point of its membrane to sodium ions. )
When a neuron receives a very strong stimulus, it may reach its threshold potential and fire an action potential. This can lead to the release of neurotransmitters, sending a signal to other neurons. The strength of the stimulus can affect the frequency of action potentials generated by the neuron.
The area of a neuron that detects a stimulus is primarily the dendrites, which are the branching extensions of the neuron. Dendrites receive signals from other neurons or sensory receptors and transmit these signals toward the cell body. In sensory neurons, specific receptors located on the dendrites are specialized to detect stimuli such as light, sound, or touch. This initial detection is crucial for initiating the neuronal response to various environmental signals.
