Siyaqondakala isegazini, ngoko kukho zingqondweni, oko kukuthi, isole. Enye indlela amele kuphela indlela isikhonkwane usika iglasi okanye ukhumbule ixesha elide ezifunyanwa ngengozi, njengoko isikhumba "amaqhuma irhanisi baleka uyaganga."

Isikali pilomotornogo reflex, piloerection okanye ubonise imeko ekusebenzeni kwenkqubo luvo yabantu. Ukuba i "namaqhakuva" igutyungelwe sebali kuphela indawo yashukunyiswa, le reflex eziqhelekileyo.
