Question

Juan picks up a steel utensil and immediately drops it because it’s extremely hot. How does the reflex arc work to protect Juan from a worse burn?

In a reflex arc, the 1.)____ neuron carries the action potential from the 2.)____ .
1.)
- Motor
- Relay
- Sensory
2.)
- Brain to the spinal cord
- Sense organ to the brain
- Spinal cord to the muscle

Answer 1

Answer:

1. Motor, 2. spinal cord to muscle

Explanation:

motor neurons are the second part of a reflex arc that actually causes the movement associated with the reflex arc.

Answer 2

Answer:

The correct answer will be option-

1. Motor neuron

2. Spinal cord to muscle

Explanation:

The reflex arc is the mechanism which controls the immediate response to the stimulus called reflex action.

In a reflex arc, the main components involved are the receptors, sensory neurons, motor neurons, muscles and spinal cord.

The sensory neurons transmit the signals from the sense organ to the spinal cord where it analyses the situation and transmits the action potential back to the muscle via motor neuron.

Thus, the selected options are correct.
