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.
I really, really think it might be C. because they both can, only flat worms live in intestines and and roundworms have a pseudocoelom not a coelom. B also through me off because flat worms are symmetric.
