Answer 1

Question no 1

Reflex arc is the reflex action that take place through anatomical pathway

It has receptors that begin the pathway . The receptor are stimulated causing the propagation of the stimulus as impulse to the afferent nerves .

The afferent nerve transmit the signals to the centre . They are the sensory nerves .

The centre is the one that receive the sensory impulses and generate appropriate motor impulse in response to the stimuli . It can be brain or spinal cord .

The efferent berve come next into action which will be a motor nerve that transmit the impulse from center to the efferent organ .

Efferent organ is the one where action occur in response to the stimuli

This is reflex arc and the neural pathway it conducts
