Question

Which structure is at work when the body deals with reflex actions?

meninges
brain stem
vertebral column
Ospinal cord

Answer 1

Answer: Meninges, brain stem, vertebral column, spinal cord.

Step-by-step explanation:

A reflex action can be defined as the involuntary and instantaneous movement of the body towards the stimulus. The reflex action is generated as a response in the neural pathway called reflex arcs that includes the meninges of the brain, brain stem, spinal cord and vertebral column that sends electrical impulses to the muscles, and other parts of the body to give response towards stimulus.

Answer 2

spinal cord

Step-by-step explanation:

Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.

Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.

Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.

Hence, the correct option is spinal cord.
