Rostral and caudal: In animals with linear nervous systems, the term rostral (from the Latin rostrum, meaning "beak") is synonymous with anterior and the term caudal (from the Latin cauda, meaning "tail") is synonymous with posterior. Due to humans having an upright posture, however, our nervous system is considered to bend about 90°.

For example, the eyes are rostral to the back of the skull, and the tailbone is caudal to the chest. Cranial and caudal, which describe structures close to the top of the skull (cranial), and towards the bottom of the body (caudal).

Rostral (from Latin rostrum 'beak, nose') describes something situated toward the oral or nasal region, or in the case of the brain, toward the tip of the frontal lobe. [ 39 ] Cranial (from Greek κρανίον 'skull') or cephalic (from Greek κεφαλή 'head') describes how close something is to the head of an organism.

The rostral bone is a novel bone found in ceratopsians. An unpaired element, it caps the front of the premaxillae at the tip of the snout. [ 25 ] : 36 When used as an adjective, the term rostral refers to the rostrum .
The rostral neuropore or anterior neuropore is a region corresponding to the opening of the embryonic neural tube in the anterior portion of the developing prosencephalon. The central nervous system develops from the neural tube, which initially starts as a plate of cells in the ectoderm and this is called the neural plate, the neural plate ...
The fastigial nuclei is situated atop the roof of the fourth ventricle (thence its name: "fastigus" is Latin for "summit"). [1]The fastigial nucleus is a mass of gray matter nearest to the middle line at the anterior end of the superior vermis, immediately over the roof of the fourth ventricle (the peak of which is called the fastigium), from which it is separated by a thin layer of white matter.
