Prosternum with stridulatory sulcus (notch for beak); with three segments, short, strong.
In these the tentacles are stunted or suppressed and the mesenteries are ill-developed, but the sulcus is unusually large and has long cilia.
The stomodaeum is compressed laterally, and is furnished with two longitudinal grooves, a sulcus and a sulculus.
Each zooid has six tentacles; the stomodaeum is elongate, but the sulcus and sulculus are very feebly represented.
The sulcus bifurcates on the unforked part of the organ at a point about two-thirds of the distance from the base to the division of the organ.
The basal parts of the two heads are covered with moderate sized spines, those closest to the base and the sulcus being the smallest.
The sulcus is a deep groove between heavy folds proximally and is a shallower furrow distally (Figure 4).
The sulcus bifurcates at the third subcaudal scale.
The sulcus is bifurcate; the fork is near the base and almost gives the appearance of two sulci on some specimens.
Every principal gyrus and sulcus of a chimpanzee's brain is clearly represented in that of a man, so that the terminology which applies to the one answers for the other.
Small loose bodies are generally carried, by the increased lachrymal secretion, along the sulcus formed by the apposition of the eyelids, to the inner canthus, and there discharged.
The saw is then made to turn steadily and lightly, pressure being made when the instrument is moving from left to right, until a pretty deep sulcus is made.
I stopped the hole five or six times after this, but she had learned a lesson; she always got into the sulcus between the bricks before attempting to remove the paper.
It is then carried across the sulcusand is made to emerge through the opposite lip of the cervix.
The sulcus interparietalis, which begins farther outward than in the ordinary human being, receives the sulcus parieto-occipitalis--a structure in conformity with the typical brain of the ape.
The gyrus occipitalis primus is separated from the upper parietal lobe by the sulcus parieto-occipitalis, a formation that, according to Gratiolet, exists in many apes.
The name was based on an upper incisor bearing a single median sulcus and an associated lower jaw containing all of the cheek teeth from the Benson local fauna, Cochise County, Arizona.
The single deep, median sulcus on the outer surface of the upper incisor is slightly displaced to the inner side of the tooth.
It differed in position from the similar fissures described by Meynert and Sander in that it did not, as in these cases, unite with the internal perpendicular occipital sulcus and thus simulate the arrangement found in the anthropoid apes.
On the left side gyri and sulci were few and simple but typical, the external perpendicular occipital sulcus being interrupted by a broad crossing gyrus.
This variety, which is met with among those who handle septic material, occurs in the sulcus between the nail and the skin, and is due to the introduction of infective matter at the root of the nail (Fig.
The nails should be cut down till there is no sulcus between the nail edge and the pulp of the finger in which organisms may lodge.
A muscular ridge, called the crista terminalis, corresponding to the sulcus terminalis on the exterior.
From the superior commissure of the meatus to the sulcus in the rear of the corona its topographical outline may be said to describe two opposite segments of a circle, as seen in the cuts representing the glans in its natural shape.
The humero-pectoral sulcus crosses the plastron behind the entoplastron in a straight line, and reaches the border anterior to the axillary notch.
This lobe is almost entirely surrounded by a deep sulcus called the limiting sulcusof Reil, which insulates it from the adjacent gyri.
Another very ancient and stable sulcus is the orbital, which is a simple antero-posterior line until Man is reached (see fig.
Bisecting the internal orbital gyrus is an antero-posteripr sulcus (s.
In the sulcus between the corpus callosum and the limbic lobe a narrow band of fibres called the cingulum is seen, most of its fibres only run a short distance in it and link together adjacent parts of the brain.
The palpi are contiguous throughout and are fused for most of length though a median furrow or sulcus above and one below run to base; projecting forward; together they narrow distad, with outline triangular; shorter than prostomium.
Ventral plates sharply limited, elevated; all of abdominal plates bisected by the median longitudinal sulcus excepting the first one, which is entire.
They are separated, in Mammalia at all events, on their inner aspect from the infundibular region by a somewhat S-shaped groove, known as the sulcus of Munro, which ends in the foramen of Munro.
In the grooved tooth, a sulcusruns along the anterior or outer surface, its object being to convey into the wound the secretion of a poison gland.
This sulcus is but faintly indicated in the Raccoon.
It is rather robust, very much recurved and grooved by a deep vertical sulcus upon its antero-internal face.
The single median sulcus on the anterior face of each incisor is typical of the genus Cratogeomys.
