Ho anatomy, orbit ke lesoba kapa mokoti oa lehata moo leihlo le likarolo tsa lona li leng teng."Orbit" e ka bolela sokete ea masapo.Bophahamo ba potoloho ho motho e moholo ke limililithara tse 30, leihlo le nka 6.5 ml ea kakaretso.Likahare tsa orbital li kenyelletsa leihlo, orbital le retrobulbar fascia, mesifa ea extraocular, methapo ea cranial, methapo ea mali, mafura, tšoelesa ea lacrimal le mokotla oa eona le duct, mahlo, li-medial le lateral palpebral ligaments, hlahloba li-ligaments, suspensory ligament, septum. , ciliary ganglion le methapo e khutšoanyane ea ciliary.
