Question

Which of the following lists the parts of a reflex are in the corret order?

A) receptor, sensory neuron, interneuron, motor neuron, effector
B) receptor, effector, sensory neuron, interneuron, motor neuron
C) receptor, sensory neuron, effector, interneuron, motor neuron
D) effector, receptor, sensory neuron, interneuron, motor neuron
E) receptor, interneuron, sensory neuron, motor neuron, effector

Answer 1

Step-by-step explanation:

The answer is sensory receptors → sensory neurons → interneurons → motor neurons. Justine took a sip of milk and immediately spat it out because she realized it had soured. The path of the messages is sensory receptors → sensory neurons → interneurons → motor neurons, in her nervous system which cause this reaction.

Sensory Receptor is that part of the nervous system that responds to stimuli

Sensory Neuron is that type of neuron that carries messages from special receptors to the central nervous system

Interneuron is the type of neuron that connects sensory and motor neurons

Motor Neuron is the type of neuron that carries messages from the central nervous system to effectors

Answer 2

A) receptor, sensory neuron, interneuron, motor neuron, effector

Step-by-step explanation:

In a reflex arc, the receptors present in the skin receive stimulus and generate afferent impulse. The sensory neuron transmits the impulse to the interneuron. Interneuron is present in the spinal cord and activates it. The interneuron then sends back the impulse through the motor neurons to effectors whcih are present in the muscles for the response.
