Umunwe uyidijithi evelele emaqakaleni ezilwane eziningi ezine-tetrapod vertebrate, ikakhulukazi lezo ezinemikhawulo ( izandla) njengabantu nezinye izilwane eziphila ngaphansi kwesikhumba. Ama-tetrapod amaningi anezinombolo ezinhlanu (i-pentadactyly), [1][2] namadijithi amafushane (okungukuthi mafushane kakhulu kune-metacarpal/metatarsals) ngokuvamile abizwa ngokuthi izinzwane, kuyilapho lawo abude ngokuphawulekayo abizwa ngokuthi iminwe. Kubantu, iminwe ichazwa ngendlela eguquguqukayo futhi iyaphikiswa, isebenza njengesitho esibalulekile sokuzwa okuthintekayo nokunyakaza okuhle, okubalulekile ekuhlakanipheni kwezandla kanye nekhono lokubamba nokusebenzisa izinto.

 Abantu 
Ngokuvamile abantu baneminwe emihlanu,  amathambo abizwa ngokuthi ama-phalanges,  esandleni ngasinye, yize abanye abantu beneminwe engaphezu noma ngaphansi kwemihlanu ngenxa yezifo zokuzalwa njenge-I-polydactyly noma I-oligodactyly, noma ngenxa ngengozi noma ngenhloso. Inombolo yokuqala isithupha, ilandelwe umunwe wokukhomba, umunwe ophakathi, umunwe wendandatho, kanye umunwe omncane noma i-pinkie. Ngokwezincazelo ezahlukahlukene, isithupha singabizwa ngokuthi umunwe, noma cha.

Izichazamazwi zesiNgisi zichaza umunwe njengencazelo eyodwa kwezinhlanu ezihlanganisa isithupha, noma eyodwa kwezine ngaphandle kwesithupha (lapho zibalwa kusuka ku-1 kuya ku-4 ziqala ngomunwe wokukhomba oseduze kakhulu nesithupha).

 Amathambo 
Isithupha (esixhumene ne-i-trapezium) sitholakala ohlangothini olulodwa, eliqondene nengalo. 

Intende yesandla inamathambo amahlanu aziwa ngokuthi ama-metacarpal, elilodwa kuya kwelinye lamadijithi amihlanu. Izandla zomuntu ziqukethe amathambo edijithali ayishumi nane, abizwa ngokuthi ama-phalanges, noma Amathambo e-phalanx: amabili esithupheni (isithupha asinalo i-phalanx ephakathi) Intende yesandla inamathambo amahlanu aziwa ngokuthi amathambo e-metacarpal, elilodwa kuya kwelinye lamadijithi amahlanu. Izandla zomuntu ziqukethe amathambo edijithali ayishumi nane, abizwa nangokuthi ama-phalanges, noma amathambo e-phalanx: amabili esithupheni (isithupha asinalo i-phalanx ephakathi) futhi amathathu kumunwe ngamunye kwemine. Lawa yi-phalanx esekugcineni, ethwele uzipho, i-phalanx ephakathi, kanye ne-proximal phalanx.  Amalunga amathambo akheka noma kuphi lapho kuhlangana khona amabili noma ngaphezulu kulawa mathambo. Umunwe ngamunye unamalunga amathathu
