IHalata & Munger (1986) ibika ukuthi ukuminyana kwezitho zangasese kukhulu kakhulu e-corona glandis, kuyilapho umbiko kaYang & Bradley (1998) "ungakhombisanga zindawo ezisezintanjeni ezingahlehliswa kakhulu kunezinye."

IHalata & Spathe (1997) ibike; "lo glans umthondo iqukethe predominance mahhala kwalapho, eziningi zangasese ekupheleni ama futhi akuvamile Pacinian futhi Ruffinian corpuscles. Ukuphela kwemizwa kaMerkel nezidumbu zikaMeissner azikho. "

U-Yang noBradley baphikisana; "iphethini ehlukile yokugcinwa kwama-glans igcizelela indima ye-glans njengesakhiwo sezinzwa". Abanye abacwaningi baphakamise ukuthi i-glans iguqukele ekubeni yi-acorn, amakhowe noma isigaxa esakhiwe ukuze kuthi ngesikhathi sokukopisha sisebenze ukususa noma yisiphi isidoda esisekhona kubalingani bobulili bangaphambilini, kepha lokhu akusekelwa lapho kubhekwa izihlobo ze-primate ezinokuziphatha okuhlukile kokukhwelana.
