Inferior Anastomotic Vein
The inferior anastomotic vein, also known as the vein of Labbe, is one of several superficial cerebral veins on the human brain. It was named after the 19th century French surgeon Charles Labbé (1851–1889), the nephew of the surgeon and politician Léon Labbé (1832–1916). It crosses and anastomoses at its two ends with the middle cerebral vein and the transverse sinus. The appearance and structural anatomy of the vein itself appears to be highly variable within the human population. The vein drains its adjacent cortical regions gathering tributaries from minor veins of the temporal lobe The temporal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. The temporal lobe is involved in pro ....

Superficial Cerebral Veins
The superficial cerebral veins are a group of cerebral veins in the head. This group includes the superior cerebral veins, the superficial middle cerebral vein, the inferior cerebral veins, the inferior anastomotic vein and the superior anastomotic vein The superior anastomotic vein, also known as the vein of Trolard, is a superficial cerebral vein grouped with the superior cerebral veins. The vein was eponymously named after the 18th century anatomist Jean Baptiste Paulin Trolard. The vein anas .... Veins of the head and neck {{circulatory-stub ...

Human Brain
The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head. The cerebrum, the largest part of the human brain, consists of two cerebral hemispheres. Each hemisphere has an inner core composed of white matter, and an outer surface – the cerebral cortex – composed of grey matter. The cortex has an outer layer, the neocortex, and an inner allocortex. The neocortex is made up of six neuronal layers, while the allocortex has three or four. Each hemisphere is conventionally divided into four lobes – the frontal, temporal, parietal, and occipital lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Labbé
Charles Labbé was a French surgeon, born October 8, 1851, Merlerault, and died October 22, 1889, Paris. He discovered what is now known as the vein of Labbé (inferior anastomotic vein) in his 3rd year of medical school. Biography He was the son of Alexandre Labbé (1823–1888) and Marie Chapey (1830–?), born in a small village in Normandy called Merlerault in the district of Orne, where his father was notary. He entered the medical faculty in Paris in 1871, probably inspired by his uncle, the surgeon Léon Labbé (1832–1916) who is remembered for Labbé's triangle. On March 13, 1882, Labbé defended his thesis for the medical doctorate. In 1885 he married Marie Eugenie Boussatón (1863–1891). They had one child, Suzanne, born 1889. Charles Labbé died shortly (three weeks) after the birth of his daughter. In 1879, the article entitled "''Note sur la circulation veineuse du cerveau et sur le mode de développement des corpuscules de Pacchioni''" was published in the "'' ...

Léon Labbé
Léon Labbé (September 29, 1832 – March 21, 1916) was a French surgeon and politician who was born in the village of Le Merlerault in the department of Orne. He was an uncle to physician Charles Labbé (1851–1889), who first described the inferior anastomotic vein ( vein of Labbé). From 1856 to 1860 Labbé was a hospital intern in Paris, and in 1861 earned his medical doctorate. Afterwards, he was a surgeon at several hospitals in Paris, including the Hôpital Beaujon, where he was chief-surgeon for many years. In 1879 he became a member of the Académie de Médecine. In 1892 he was elected to the Senate representing the department of Orne. In this role, he introduced various laws of interest to the medical community, including the 1914 ''Loi Labbé'' (Labbé Law), legislation that provided compulsory anti-typhoid vaccinations for French soldiers.

Anastomosis
An anastomosis (, plural anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf#Veins, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale (heart), foramen ovale in a fetus's heart) or abnormal (such as the atrial septal defect#Patent foramen ovale, patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital disorder, congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Gre ...

Middle Cerebral Vein
The middle cerebral veins are the superficial middle cerebral vein and the deep middle cerebral vein. * The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere, running along the lateral sulcus, and ends either in the cavernous sinus or the sphenoparietal sinus. * The deep middle cerebral vein (deep Sylvian vein) receives tributaries from the insula and neighboring gyri, and runs in the lower part of the lateral sulcus. Connections The superficial middle cerebral vein is connected: # with the superior sagittal sinus by the superior anastomotic vein (vein of Trolard) where the latter opens into one of the superior cerebral veins; # with the transverse sinus by the inferior anastomotic vein (vein of Labbé) which courses over the temporal lobe The temporal lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The temporal lobe is located beneath the lateral fissure on both c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transverse Sinus
The transverse sinuses (left and right lateral sinuses), within the human head, are two areas beneath the brain which allow blood to drain from the back of the head. They run laterally in a groove along the interior surface of the occipital bone. They drain from the confluence of sinuses (by the internal occipital protuberance) to the sigmoid sinuses, which ultimately connect to the internal jugular vein. ''See diagram (at right)'': labeled under the brain as "" (for Latin: ''sinus transversus''). Structure The transverse sinuses are of large size and begin at the internal occipital protuberance; one, generally the right, being the direct continuation of the superior sagittal sinus, the other of the straight sinus. Each transverse sinus passes lateral and forward, describing a slight curve with its convexity upward, to the base of the petrous portion of the temporal bone, and lies, in this part of its course, in the attached margin of the tentorium cerebelli; it then leaves th ...

Temporal Lobe
The temporal lobe is one of the four Lobes of the brain, major lobes of the cerebral cortex in the brain of mammals. The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. ''Temporal'' refers to the head's Temple (anatomy), temples. Structure The Temple (anatomy)#Etymology, temporal Lobe (anatomy), lobe consists of structures that are vital for declarative or long-term memory. Declarative memory, Declarative (denotative) or Explicit memory, explicit memory is conscious memory divided into semantic memory (facts) and episodic memory (events). Medial temporal lobe structures that are critical for long-term memory include the hippocampus, along with the surrounding Hippocampal formation, hippocampal region consisting of the Perirhinal cortex, perirhinal, ...
