Which of these lists the components of a reflex arc in the correct sequence? Which of these lists the components of a reflex arc
in the correct sequence? receptor; efferent neuron; control center; afferent neuron; effector receptor; efferent neuron; effector; afferent neuron; control center receptor; afferent neuron; control center; efferent neuron; effector receptor; afferent neuron; efferent neuron; control center; effector R
Receptor, afferent neuron, control center, efferent neuron, effector muscle (the options are not given in the correct way therefore the options are arranged in sequence)
Explanation:
Reflex arc refers to the neuronal pathway which is activated during the reflex or emergency actions in the body.
The reflex arc pathway is a very fast response as it shortens the time of the neuronal pathway.
When the receptor senses the reflex stimuli, it immediately generates the signals and transmits them to the spinal cord through the afferent or sensory neuron. When the signal reaches the spinal cord then the signals are perceived by the interneurons or control centre of the spinal cord and then transmit the response to the effector muscle through the efferent neuron or the motor neuron. This whole pathway is followed in just a few milliseconds.
The angle at which the sun rays strike the earth at the equator is more or less 90 degrees while you move towards the poles, it much less than this. This means that the unit of sunlight per surface area received at the equator is higher than that at the poles. This is why the equator is always warmer than the poles.
