Sickle cell trait is apparently an adaptation for the prevention of Malaria.  Sickle cell trait is a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein hemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria. As a result, the frequencies of sickle cell carriers are high in malaria endemic areas.

The efferent neuron or motor neuron causes changes at the effector, which are the skeletal muscles, for adequate integration and responsiveness.

Reflex action refers to the full series of actions. The reflex arc is the name of the route.

Somatic receptor followed by afferent nerve fiber, interneurons, efferent nerve fiber, and skeletal muscle constitutes the proper order.
