Plural form of gubernaculum; anatomically, cord-like structures in developing organisms that guide movement or positioning of organs.
From Latin gubernaculum, 'rudder' or 'helm,' from gubernare 'to steer or govern.' Medical use adopted the metaphor of steering or guiding, as these structures guide gonadal descent.
Gubernacula are literally 'little rudders'—embryologists borrowed the steering metaphor because these cords actually do pilot your developing reproductive organs into position before birth. Etymology meeting anatomy perfectly.
