In spiders, the rostrum is a part of the mouth of which it borders the opening in front.Homologous of an upper lip, this outgrowth is especially characterised by the presence of a pocket-shaped secreting organ, the rostral gland, only accessible by the sole means of histology and electron microscopy (external link "archentoflor").
For example, to describe the human brain, "rostral" still means "towards the beak or snout (Latin rostrum)", or at any rate, the interior of the cranial cavity just behind the face. "Caudal" means "towards the tail (Latin cauda "), but not "towards the back of the cranial cavity", which is "posterior" (behind, in ordinary motion).

In the anatomy of the brain of vertebrates, the forebrain or prosencephalon is the rostral (forward-most) portion of the brain.The forebrain controls body temperature, reproductive functions, eating, sleeping, and the display of emotions.
The rostral ventrolateral medulla (RVLM), also known as the pressor area of the medulla, is a part of the ventrolateral medulla in the brainstem responsible for basal and reflex control of sympathetic activity associated with cardiovascular function. [1]
