Answer:
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 list of the components of a reflex arc in the correct sequence is: C. receptor; afferent neuron; control center; efferent neuron; effector.
Reflex arc can be defined as the neural (nerve) pathway that controls the immediate and involuntary response of a living organism to a particular stimulus.
Hence, a reflex arc is usually activated during a reflex, which is an involuntary, unplanned sequential action of the body of a living organism in response to a stimulus.
The components of a reflex arc in the correct sequence include the following:
1. Receptor: it is responsible for sensing a reflex stimuli and the transmission of the associated nerve signals to the spinal cord, through the afferent neuron.
2. Afferent neuron: it is the medium through which nerve signals are transmitted to the spinal cord.
3. Control center: this is where the nerve signals are perceived and then transmitted as a response to the effector muscle, through the efferent neuron.
4. Efferent neuron: it is serves as the medium through which a response is transmitted to the effector muscle.
5. Effector: these are the muscle cells that produce a response in living organisms.
