A boy cuts his hand while playing in the park. The stimulus reaches the interneurons. What nerve pathway will this stimulus signal continue to follow in order to lift his hand from the sharp object? (3 points) Question 7 options: 1) Motor neuron, effector 2) Motor neuron, receptor 3) Sensory neuron, effector 4) Sensory neuron, receptor

This is known as the reflex arc in the human body, first it starts off externally like a sharp object in the environment (stimuli), next the sensory receptor detects this pain (stimulus), passes into sensory neuron and jumps a space known as the synapse, then intp the spinal cord, where the interneurons will be found, the stimulus gets passed to the motor neuron and then travels finally to the effector muscle. This results in the boy moving his hand away from the sharp object.

Answer: 1

Explanation:

When the receptor(sensory neuron) is stimulated, it sends a message to a part of your body that effects the correct response. This is called the effector(motor neuron.

Receptor in the skin detects a stimulus (pain, the change in temperature).

Motor neuron sends electrical impulses to an effector.

Effector produces a response makes muscle contracts to move hand away.

For example, keeping hold of a hot object requires a nerve impulse to be sent to the motor neuron of the reflex arc to interfere with the normal reflex action to drop the object.
