Head V is a 1949 painting by Irish-born British artist Francis Bacon, one of the series of works made in 1949 for his first one-man exhibition at the Hanover Gallery, in London. It measures 82 by 66 centimetres (32 in × 26 in) and is held in a private collection. The painting is part of a series of six works from the late 1940s depicting heads.
The circle of Willis is a part of the cerebral circulation and is composed of the following arteries: [3] Anterior cerebral artery (left and right) at their A1 segments; Anterior communicating artery; Internal carotid artery (left and right) at its distal tip (carotid terminus) Posterior cerebral artery (left and right) at their P1 segments
The external capsule is a series of white matter fiber tracts in the brain. These fibers run between the most lateral (toward the side of the head) segment of the lentiform nucleus (more specifically the putamen) and the claustrum. The white matter of the external capsule contains fibers known as corticocortical association fibers.
Both the left and right hemispheres of the brain have a lateral geniculate nucleus, named after its resemblance to a bent knee (genu is Latin for "knee"). In humans as well as in many other primates, the LGN has layers of magnocellular cells and parvocellular cells that are interleaved with layers of koniocellular cells.
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into:
The left and right parts separate, but there is also an anterior/posterior divergence. The posterior fibers (called the postcommissural fornix ) of each side continue through the hypothalamus to the mammillary bodies ; then to the anterior nuclei of thalamus via the mammillothalamic tract .
For instance, another recent study found that reducing processed meat intake by 30% or about 8.7 grams per day — meaning eating at least five fewer slices of bacon per week — over 10 years ...
Hippocampus in the human brain Nissl-stained coronal section of the brain of a macaque monkey, showing hippocampal formation and subfields (circled). Hippocampus anatomy describes the physical aspects and properties of the hippocampus, a neural structure in the medial temporal lobe of each cerebral hemisphere of the brain.
