Occasional myocytes in both ventricles showed hypereosinophilia and loss of myofibril structure without associated inflammation (changes regarded as agonal rather than representing intrinsic myocyte pathology).

-
At operation, dense adhesions between the left lung and the right and left ventricle were present.
-
The right ventricle was markedly hypertrophied and dilated, consistent with severe cor pulmonale.
-
The cerebellum, formed in the same way by projection from the summit of the spinal cord, making two leaves that come together on the median line, has also a cavity contained between them, and just behind the medulla oblongata, which is finally reduced to the little space called the fourth ventricle, when the cerebellum grows to become a solid body.

-
(VSD) - one or more holes in the muscular wall that separates the right and left ventricles of the heart; for more detailed information, please see the ventricular septal defect page in the Index of Medical Conditions.
Alagille Syndrome Glossary
-
From his theory of the action of the air through the nose on the contents of the ventricles of the brain is explained his use of sternutatories, and his belief in the efficacy of sneezing.
-
From the lateral ventricles CSF drains into the central third ventricle, and thence through the aqueduct in the midbrain into the fourth ventricle.
-
Leusen initiated the modern investigation of central chemoreception in 1950, using perfusion of the cerebral ventricles with artificial cerebrospinal fluid in anesthetized dogs.
-
The key components of this malformation include hypoplasia of the cerebellar vermis and cystic dilatation of the 4th ventricle.
-
A tricuspid regurgitant murmur may be heard, becoming more prominent as the right ventricle dilates.
-
Both groups of children were born with left ventricles that, on average, had higher mass and lower contractility, or a diminished ability to pump.
-
However, right ventricular dysfunction was not always present in our series, and in patients with a right atrial thrombus, it was often seen to prolapse through the tricuspid valve into the right ventricle.
-
While moving between these ventricles, this spirit passes through the common space, where it is "digested" and converted into a "finer and clearer spirit" by mixture with the "power of the soul.
Architecture and Memory: The Renaissance Studioli of Federico da Montefeltro
-
So far on call tonight, we had a kid who coded requiring chest compressions and intubation, a newborn double-outlet right ventricle who needed lines, and a micro preemie who needs to be tapped.
-
Methods Our recent approach is to reconstruct the dilated right ventricle outflow tract (RVOT) as a fibro-muscular sleeve to support a pulmonary homograft valve conduit in orthotopic position.
-
The septum pellucidum stretches across the interval between the genu of the corpus collosum and the columns of the fornix, separating the frontal horns of the two lateral ventricles.
-
Arteries carried in with the pial fold provide the choroid plexuses of the 3rd and lateral ventricles.
-
Sometimes both nerves are involved -- for example, in fracture implicating both sides of the anterior fossa, and in tumours, particularly gumma, growing in the region of the floor of the third ventricle.

-
Blood flows from the atria to the ventricles through a one-way valve.
-
In these cases, such as hydrancephaly and holoprosencephaly, the ventricles are not only relatively enlarged but also often distorted due to overlying parenchymal abnormalities.
Hydrocephalus
-
The central part (pars centralis ventriculi lateralis; cella) (Fig. 737) of the lateral ventricle extends from the interventricular foramen to the splenium of the corpus callosum.

-
Finally, the perceived object could enter into the rear ventricle of the brain, the memory.
-
The passive, elastic recoil between systoles maintains the blood pressure, smooths the flow of blood, and forces blood through the coronary arteries while the ventricles are filling.
-
An echocardiogram excluded major pericardial effusion, showing a non-dilated left ventricle with inferior wall akinesia and overall moderate function.
-
It consists of (a) the myelencephalon, comprising the medulla oblongata and the lower part of the fourth ventricle; (b) the metencephalon, consisting of the pons, cerebellum, and the intermediate part of the fourth ventricle; and (c) the isthmus rhombencephali, a constricted portion immediately adjoining the mid-brain and including the superior peduncles of the cerebellum, the anterior medullary velum, and the upper part of the fourth ventricle.
IX. Neurology. 4a. The Hind-brain or Rhombencephalon
-
One area is the subventricular zone of the lateral ventricles, which are fluid-filled cavities in both brain hemispheres connected to the central canal of the spinal cord.
-
The corpora mammillaria (corpus albicantia) are two round white masses, each about the size of a small pea, placed side by side below the gray substance of the floor of the third ventricle in front of the posterior perforated substance.

-
The computed tomography said it all; a malignant intrinsic tumour at the trigone of the lateral ventricle, probably a glioblastoma.
-
sections from the left ventricle showed diseased tissue
