The popliteal fossa sometimes referred to as the hough, 1 or kneepit in analogy to the armpit is a shallow depression located at the back of the knee joint.The bones of the popliteal fossa are the femur and the tibia.
22 Jul 20 7 description of lo ion , boundaries , structures in the floor, openings, ventricle is diamond shaped and is also known as rhomboid fossa.
The vagal trigone overlies the dorsal vagal nucleus and is situated on the caudal end of the rhomboid fossa or & 39;floor& 39; of the fourth ventricle. The area postrema is situated just before the obex, the inferior apex of the caudal ventricular floor. Both the funiculus separans and area postrema have a similar thick ependyma-containing tanycyte .
The floor i.e. the anterior edge of the fourth ventricle constitutes the rhomboid fossa, and comprises a number of general features. A sulcus - the median sulcus - extends the length of the ventricle from the cerebral aqueduct of the midbrain to the central canal of the spinal cord , dividing the floor into right and left halves.
Because superficial motor structures of the rhomboid fossa can be identified by reach the floor of the fourth ventricle medial to the nucleus nervi abducentis.

SummaryDescribed are: .Length and width values of the rhomboid fossa.2.Number and development of the transverse and oblique striae in the bottom area of
Winding around the inferior cerebellar peduncle in the lower part of the fourth ventricle, and crossing the area acustica and the medial eminence are a number of white strands, the medullary striae, which form a portion of the cochlear division of the vestibulocochlear nerve and disappear into the median sulcus.
The rhomboid fossa is a rhombus-shaped depression that is the anterior part of the fourth ventricle. Its anterior wall, formed by the back of the pons and the medulla oblongata, constitutes the floor of the fourth ventricle.
The latter end by arborizing around the cells of the medial nucleus, which is situated in the area acustica of the rhomboid fossa. The ascending fibers either end in the same manner or in the lateral nucleus, which is situated lateral to the area acustica and farther from the ventricular floor.
Jan 2 , 2009 The floor of the fourth ventricle, or rhomboid fossa, is divided into three Guide pour l& 39;étude de leur structure à l& 39;état normal et pathologique,
Jun 30, 20 6 The choroid plexus is attached to the adjacent brain structures by a double layer The floor of the fourth ventricle is named the rhomboid fossa.

In the upper part of the medulla oblongata, the hypoglossal nucleus approaches the rhomboid fossa, where it lies close to the middle line, under an eminence named the hypoglossal trigone. It is a slight elevation in the floor of the inferior recess of the fourth ventricle, beneath which is the nucleus of origin of the twelfth cranial nerve.
Rhomboid Fossa fossa rhomboidea; “floor” of the fourth ventricle Fig. 709 .—The anterior part of the fourth ventricle is named, from its shape, the rhomboid
This structure, in turn, is found in the floor of the rhomboid fossa just lateral to the median sulcus and rostral to the striae medullares of the fourth ventricle. The
There are several structures visible on the anterior surface of the medulla – namely the three fissures/sulci, the pyramids, the olives, and five cranial nerves.
Brainstem lesions of the rhomboid fossa, cysts and tumours of the fourth ventricle Further he described its boundaries formed by blood vessels of the pia running sequence, highlight cerebrospinal fluid unlike its neigh borhood structures.
These structures bounding the lateral ventricles form a frame curving around the thalamus, which itself constitutes the main structure bounding the third ventricle. Indeed, were it not for the choroid plexus, a cleft-like opening would be all that lay between the lateral ventricle and the thalamus; this cleft constitutes the lower part of the choroid fissure .
Floor Rhomboid Fossa . The floor of the fourth ventricle is diamond-shaped. It is covered by a The floor is divided into right and left halves by a median sulcus.
The floor of the third ventricle is formed by hypothalamic structures and this can be opened surgically between the mamillary bodies and the pituitary gland in a procedure called an endoscopic third ventriculostomy. An endoscopic third ventriculostomy can be performed in order to release extra fluid caused by hydrocephalus.
The anterior part of the fourth ventricle is named, from its shape, the rhomboid fossa, and its anterior wall, formed by the back of the pons and medulla oblongata,
The vagal trigone overlies the dorsal vagal nucleus and is situated on the caudal end of the rhomboid fossa or & 39;floor& 39; of the fourth ventricle. The area postrema is situated just before the obex, the inferior apex of the caudal ventricular floor.
The rhomboid fossa is a rhombus -shaped depression that is the anterior part of the fourth ventricle. Its anterior wall, formed by the back of the pons and the medulla oblongata, constitutes the floor of the fourth ventricle.
The pontine tegmentum is all the material dorsal from the basilar pons to the fourth ventricle. Along with the dorsal surface of the medulla, it forms part of the rhomboid fossa – the floor of the fourth ventricle.
30 Jun 20 6 The choroid plexus is attached to the adjacent brain structures by a double layer The floor of the fourth ventricle is named the rhomboid fossa.
Jul 22, 20 7 description of lo ion , boundaries , structures in the floor, openings, ventricle is diamond shaped and is also known as rhomboid fossa.
This is an extremely serious condition regardless of the cause of blockage. An endoscopic third ventriculostomy is a surgical procedure for the treatment of hydrocephalus in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole.
Ventricular system of the brain with neighboring structures. Floor. The floor of the fourth ventricle is also referred to as the rhomboid fossa because of its shape.
In the human brain, the rhomboid fossa is divided into symmetrical halves by a median sulcus which reaches from the upper to the lower angles of the fossa and is deeper below than above. On either side of this sulcus is an elevation, the medial eminence, bounded laterally by a sulcus, the sulcus limitans.

The facial colliculus is an elevated area located on the pontine tegmentum dorsal pons in the floor of the fourth ventricle.It is formed by fibers from the facial motor nucleus of the facial nerve cranial nerve VII as they loop over the abducens nucleus.
