It also shews the wide opening of the infundibulum in the middle line into the base of the brain.
To the infundibulum there leads a narrow canal lined by a columnar epithelium which becomes the gastric cavity.
In the later stages of development the infundibulum becomes gradually prolonged, and forms an elongated diverticulum of the third ventricle, the apex of which is in contact with the pituitary body (figs.
The part of the infundibulum which lies at the hinder end of the pituitary body is at first a simple finger-like process of the brain (fig.
Along the sides of the infundibulumrun the commissural fibres connecting the floor of the mid-brain with the cerebrum.
After the pituitary vesicle has lost its connection with the mouth it lies just in front of the infundibulum (figs.
The process of the infundibulumthus metamorphosed becomes inseparably connected with the true pituitary body, of which it is usually described as the posterior lobe.
The floor is prolonged into an infundibulum (in) which contains a prolongation of the third ventricle.
The part of the infundibulum which undergoes this change is very probably homologous with the saccus vasculosus of Fishes.
In Mammalia the posterior part of the primitive infundibulum becomes the corpus albicans, which is double in Man and the higher Apes; the ventral part of the posterior wall forms the tuber cinereum.
This pit rapidly deepens, and soon extends itself backwards nearly as far as the infundibulum (fig.
In Birds, Reptiles, and Amphibia the lower part of the embryonic infundibulum becomes atrophied and reduced to a mere finger-like process--the processus infundibuli.
The morphological anterior end of the central nerve tube is the point of the infundibulum which is in contact with the pituitary body.
On the sides of the infundibulum are placed two prominent bodies, the lobi inferiores (l.
The sides of the infundibulumexhibit two lobes, the lobi inferiores (Plate 37, fig.
In front of the infundibulum is the optic chiasma (Plate 37, fig.
Below, the thalamencephalon is produced into a very elongatedinfundibulum (Plate 37, figs.
The apex of the infundibulum is enlarged, and to it is attached a pituitary body (pt.
It is a long, tapering tube which passes ventrally and terminates blindly at the infundibulum in Ammocoetes.
The notochord always terminates at the infundibulum, and the trabeculae always enclose a pituitary space, in which lies the infundibulum (inf.
In the stage between the two it may well have opened into an intermediate gut, the notochordal tube, its separation from which would leave the end of the {441}notochord blind, just as it had already left the end of the infundibulum blind.
The strings of the racquet are represented by a thin membrane, in the centre of which the position of the infundibulum (Inf.
But if theinfundibulum was the old oesophagus, what then?
He then speaks of the third or middle ventricle, and one posterior, which seems to correspond with the fourth; and describes the infundibulum under the names of lacuna and emboton.
The table is broader, and the infundibulum is deeper.
The tables of the lateral incisors will be fully formed, and the infundibulum is rarely obliterated, while its margin is always circumscribed and well defined, as the previous wood-cuts will indicate.
Illustration] In the above representation of the table of a three year old tooth, it will be remarked that the infundibulum appears in the outward direction to extend quite across the surface.
The anterior edges alone are rendered level; all posterior to the infundibulum being as yet untouched.
This tooth is sometimes called the shell tooth, on account of its infundibulum being, for the most part, better exhibited and longer retained than in the other incisors.
In those tables, it will be seen the infundibulum has gone from a central nipper only; but even in that instance, a white mark indicates that the cavity is merely filled up by crusta petrosa, the enamelled lining not being yet worn out.
The infundibulum is broad, as depicted in the accompanying cut.
The tables of the lateral incisors, on the contrary, are only beginning to be formed, and very often the part posterior to the infundibulum has not received any attrition.
The reader will remark the infundibulum of the corner tooth has become circumscribed, being now encircled by a flattened surface, which posteriorly is of some width.
Posterior to the infundibulum the lamina inferior and oblique cartilage join to form the planum terminale (pla.
The lamina superior terminates at the level of the infundibulum (inf.
The infundibulum dilates into two rounded bodies, the lobi inferiores, while the pituitary body or hypophysis cerebri has two lateral diverticula known as sacci vasculosi.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "infundibulum" in a variety of sentences. We hope that you will now be able to make sentences using this word.
