Glava
Glava je početni ili vršni dio životinjskog tijela, koji se nalazi na prednjoj ili gornjoj strani organizma. Ovaj tjelesni segment ima većina životinja, osobito one sa bilateralnom (dvobočnom) simetrijom. Kada su u glavenoj regiji koncetrirani i čulni i nervni sistem, ta pojava se označava kao cefalizacija.[1][2][3][4]
Prednji ili vršni dio glave je obično njuška, a kod čovjeka lice. Glava kopnenih, četveronožnih kičmenjaka (Tetrapoda), od ostatka tijela je odvojena vratom koji joj obično omogućava ograničene pokrete na sve strane.
Glava čovjeka
Na prednjoj strani ljudske glave je lice. Više od 30 mišića lica omogućuju ljudima da (mimikom) izraze osjećaje i raspoloženja (npr. osmijeh, mrgođenje, ljutnju, strah, tugu).
Glava se sastoji od 28 odvojenih kostiju lobanje i vilica.
