For example, in horses, the eyes are caudal to the nose and rostral to the back of the head. These terms are generally preferred in veterinary medicine and not used as often in human medicine. [42] [43] [44] In humans, "cranial" and "cephalic" are used to refer to the skull, with "cranial" being used more commonly. The term "rostral" is rarely ...
Rostral and caudal, which describe structures close to (rostral) or farther from (caudal) the nose. 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).
The cephalic flexure, also known as the mesencephalic flexure, is the first flexure or bend, that forms in the region of midbrain. [2] The caudal part of the midbrain and the rostral part of the hindbrain makes up a mibrain-hindbrain boundary region known as the isthmic organizer . [ 3 ]
The latter flexure mainly appears in mammals and sauropsids (reptiles and birds), whereas the other two, and principally the cephalic flexure, appear in all vertebrates (the sum of the cervical and cephalic ventral flexures is the cause of the 90-degree angle mentioned above in humans between body axis and brain axis).
Definition: Relationship between the longitudinal axis of fetus and mother: longitudinal (resulting in either cephalic or breech presentation) oblique (unstable, will eventually become either transverse or longitudinal) transverse (resulting in shoulder presentation) back up; back down (indication for vertical uterine incision during cesarean ...
The cephalic index is the ratio of the width of the head, multiplied by 100 and divided by its length (front to back). The index is also used to categorize animals, especially dogs and cats. The index is also used to categorize animals, especially dogs and cats.
