Lingula Of Cerebellum
The lingula is a small tongue-shaped process, consisting of four or five folia; it lies in front of the lobulus centralis, and is concealed by it. Anteriorly, it rests on the dorsal surface of the anterior medullary velum The superior medullary velum (anterior medullary velum) is a thin, transparent lamina of white matter, which stretches between the superior cerebellar peduncles; on the dorsal surface of its lower half the folia and lingula are prolonged. It fo ..., and its white substance is continuous with that of the velum. Additional images File:Slide2SEER.JPG, Cerebellum. Inferior surface. File:Slide3EER.JPG, Cerebellum. Inferior surface.

Folium (brain)
The cerebellum (Latin for "little brain") is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as or even larger. In humans, the cerebellum plays an important role in motor control. It may also be involved in some cognitive functions such as attention and language as well as emotional control such as regulating fear and pleasure responses, but its movement-related functions are the most solidly established. The human cerebellum does not initiate movement, but contributes to coordination, precision, and accurate timing: it receives input from sensory systems of the spinal cord and from other parts of the brain, and integrates these inputs to fine-tune motor activity. Cerebellar damage produces disorders in fine movement, equilibrium, posture, and motor learning in humans. Anatomically, the human cerebellum has the appearance of a separate structure attached to the bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobulus Centralis
The central lobule is a small square lobule In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, lung, liver, or kidney) that can be determined without the use of a microscope at the gross anatomy level. This is in contrast to the m ..., situated in the anterior cerebellar notch. It overlaps the lingula, from which it is separated by the precentral fissure; laterally, it extends along the upper and anterior part of each hemisphere, where it forms a wing-like prolongation (ala), on each side, as the alae of the central lobule or ''alae lobuli centralis.''

Anterior Medullary Velum
The superior medullary velum (anterior medullary velum) is a thin, transparent lamina of white matter, which stretches between the superior cerebellar peduncles; on the dorsal surface of its lower half the folia and lingula are prolonged. It forms, together with the superior cerebellar peduncle, the roof of the upper part of the fourth ventricle; it is narrow above, where it passes beneath the facial colliculi, and broader below, where it is continuous with the white substance of the superior vermis. A slightly elevated ridge, the frenulum veli, descends upon its upper part from between the inferior colliculi, and on either side of this the trochlear nerve emerges. Blood is supplied by branches from the superior cerebellar artery. Additional images File:Gray708.svg, Scheme of roof of fourth ventricle. 1. Posterior medullary velum 2. Choroid plexus 3.
