Cytoarchitecturally bounded on the rostral and lateral aspects of the hemisphere by the frontopolar area 10, the orbital area 47, and the triangular area 45; on the medial surface it is bounded dorsally by the area 12 and caudally by the subgenual area 25.
Cytoarchitecturally bounded rostrally by the ventral anterior cingulate area 24, ventrally by the ventral posterior cingulate area 23, dorsally by the gigantopyramidal area 4 and preparietal area 5 and caudally by the superior parietal area 7.
Its rostral and caudal borders are approximated by the anterior subcentral sulcus and the posterior subcentral sulcus respectively.

 Big Brook sawfish page
The blades of the rostral spines are long and flattened and are very similar in shape to the main cusp of a sharks tooth.
These oral teeth are rarer than the rostral spines, a fact related to their very small size, around 5mm (about.18 in.) long.
The rostral spines are not curved and lack the striations of the goblin but they have a lens shaped cross section that differentiates it from the porbeagles.

Both the rostral scratch and the forward swim have behavioral events during which force is exerted against a substrate.
The rostral scratch cycles were characterized by greater hip flexion and less hip extension than the forward swim cycles.
Rostral scratch and forward swim are both rhythmic behaviors in which each cycle can be represented by a sequence of stages.

 Bathynotidae
There is certainly no clear indication of a suture between the purported rostral remnant and the hypostome proper, and even so, in nearly all other trilobites with small rostral remnants, the typical pattern is for the sutures to diverge forwards, rather than converge toward an apex.
The hypostome is attached to the rostral plate by a functional transverse suture.
As is apparent, the rostral plate (pink) is fused with the hypostome (orange), so that the median body marks the border between the hypostome and the rostral plate (dotted red line).

The red lines denote the rostral aspects of the rostral maxillary sinuses; the blue arrows indicate the septae that separate the rostral and caudal maxillary sinuses.
In the horse the rostral and caudal compartments of the maxillary sinus share a slit-like communication with the middle meatus of the nasal cavity but are otherwise completely divided by the septum.
The opacity extends from the region of the ethmoid turbinates (red arrows) to the rostral aspect of the nasal cavity (yellow arrows).

Pressor response to pulsatile compression of the rostral ventrolateral medulla mediated by nitric oxide and c-fos expression
The rostral ventrolateral medulla (RVLM) contains neurons that are the major tonic source of supraspinal sympathoexcitatory outflow, and thus this area is considered to be an important center for the regulation of sympathetic and cardiovascular activities (Dampney et al., 1982).
In all rats, Evans blue was confirmed to be restricted to areas ventral to the nucleus ambiguus, caudal to the facial nucleus, and rostral to the rostral end of the lateral reticular nucleus, comparable to the RVLM as shown in our previous report (Morimoto et al., 1999).

 Pristiophoriformes: Sawsharks
A representative pristiophoroid, the Common Sawshark (Pristiophorus cirratus), showing the rostral saw, long nasal barbels, gill slits on the side of the head, and lack of an anal fin that characterizes the group.
The rostral teeth of sawsharks are replaced when broken or lost, unlike those of sawfishes (in which damaged or missing rostral teeth are not replaced).
Litters of 7 to 17 large pups - 11 to 14 inches (28 to 35 centimetres) long - are born with the long rostral teeth folded back, possibly preventing injury to the mother; smaller rostral teeth erupt between the larger ones after birth.

This corresponds to the rostral pons and mesencephalon between the level of the 5th nerve entry zone and the 3rd nerve nucleus level.
Lesions involving rostral parts of the central MassR arc may extend beyond this level reaching the meso-diencephalic junction thereby involving the region of the interstitial nucleus of Cajal.
Monocular elevation paresis and abduction paresis in the same eye may also be caused by a single ipsilateral midbrain lesion involving the probably inhibitory connection and the intramesencephalic 3rd nerve, as monocular elevation paresis may also be caused by intra-axial 3rd nerve lesions [93].

However, McCulloch's sawshark and another iuvenile nudipinnis of similar size and rostral teeth examined by me in the Australian Museum (Sydney, AMS I 21303-001) are considerably larger (44.5 to 44.6 cm long) than a newborn specimen of apparent nudipinnis (SU 25492, 27.5 cm total length) from Australia which has owenii-like even rostral teeth.

 The Stock Exchange and Rostral Columns in St. Petersburg, Russia
Very early in the history of St. Petersburg the Strelka (spit) of the Vasilievsky Island, the largest island in the Neva delta, was intended to become the heart of downtown St Petersburg.
The imposing white colonnaded building of the Stock Exchange became its focal point, and was flanked by two Rostral Columns.
The two Rostral Columns, studded with ships' prows, served as oil-fired navigation beacons in the 1800s (on some public holidays gas torches are still lit on them).
