Imicamelo yamanje ehlakaniphile ithuthukise imisebenzi emisha ehlukahlukene:
Ukuqapha ukulala: rekhoda izinga lokushaya kwenhliziyo, ukuphefumula nenye idatha ngezinzwa ezakhelwe ngaphakathi-
Ukulungiswa okuhlakaniphile: lungisa ngokuzenzakalelayo ukuphakama namandla okusekela ngokuya ngendawo yokulala
Umsebenzi wokusiza ukulala: dlala umsindo omhlophe nomunye umculo wokusiza ukulala
Ukuvuka buthule{0}: qaphela{1}}okungaphazamisi ukuvuka{2}}ngokudlidliza okuthambile
Ukunakekelwa kwe-vertebra yomlomo wesibeletho: hlinzeka ngokusekela kochwepheshe kubantu abanenkinga yomlomo wesibeletho
Le misebenzi ihloselwe ikakhulukazi amaqembu amabili amakhulu abasebenzisi: abasebenzisi abajwayelekile abaphishekela ikhwalithi yokulala kanye nabantu abakhethekile abadinga ukunakekelwa kwe-vertebra yomlomo wesibeletho. Eminye imikhiqizo-ephezulu ingalungisa nobude ngesikhathi sangempela ngokuya ngendawo yokulala, ixazulule indawo yobuhlungu lapho imicamelo evamile kunzima ukuyicabangela izindawo zokulala ezihlukene.
