Question

Which list best represents the flow of stimuli information in the body? stimuli receiver, sensory neuron, central nervous system, motor neuron, muscle or gland stimuli receiver, motor neuron, peripheral nervous system, sensory neuron, muscle or gland sensory neuron, central nervous system, stimuli receiver, muscle or gland, motor neuron central nervous system, motor neuron, sensory neuron, stimuli receiver, muscle or gland

Answer 1

The correct answer would be the first option.

The stimuli receptors receive the stimuli from the external environment which are then passed to the central nervous system (CNS; brain and spinal cord) with the help of sensory or afferent neurons.

The brain or CNS then process and produce the response signals.

These response signals are then passed to the effector organ such as muscle or gland with the help of efferent or motor neurons.

The muscle or gland then produce the response.

Answer 2

The first part is the stimuli receiver, such as the retina of an eye. Then the information goes to the sensory neuron, which is connected to the stimuli receiver.
Then the information goes to the central nervous system- the brain!

The brain then sends the information to the motor neuron, which sends it to the muscle (the first option is the correct one)
