The largest and deepest fissure in the cerebellum is named the horizontal fissure (or horizontal sulcus). It commences in front of the pons , and passes horizontally around the free margin of the hemisphere to the middle line behind, and divides the cerebellum into an upper and a lower portion.
Broca's fissure: found in the third left frontal fold of the brain. Burdach's fissure: connects the brain's insula and the inner surface of the operculum. Calcarine sulcus or Calcerine fissure: extends from the occipital of the cerebrum to the occipital fissure. Callosomarginal fissure: found in the medial surface of the cerebrum.
A radiation source is positioned behind the patient at a standard distance (most often 6 feet, 1,8m), and the x-ray beam is fired toward the patient. In anteroposterior (AP) views, the positions of the x-ray source and detector are reversed: the x-ray beam enters through the anterior aspect and exits through the posterior aspect of the chest ...
In the human brain, two-thirds of the folded cortex is buried within the sulci, if the division of the hemispheres by the longitudinal fissure is taken into account. [2] [3] The sulci and fissures are shallow and deep grooves respectively in the cortex, that organise the brain into its regions. [2] A sulcus is a shallow groove that surrounds a ...
The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.
The cerebellopontine angle is formed by the cerebellopontine fissure. This fissure is made when the cerebellum folds over to the pons, creating a sharply defined angle between them. [ 1 ] The angle formed in turn creates a subarachnoid cistern, the cerebellopontine angle cistern.
The cerebellum consists of three parts, a median and two lateral, which are continuous with each other, and are substantially the same in structure. The median portion is constricted, and is called the vermis, from its annulated appearance which it owes to the transverse ridges and furrows upon it; the lateral expanded portions are named the hemispheres.
The chest x-ray shows hyperinflation of the lungs including prominent pulmonary vascular markings, flattening of the diaphragm, and fluid in the horizontal fissure of the right lung. Signs and symptoms
