Vertebral artery dissection is one of the two types of cervical artery dissection.The other type, carotid artery dissection, involves the carotid arteries.Vertebral artery dissection is further classified as being either traumatic (caused by mechanical trauma to the neck) or spontaneous, and it may also be classified by the part of the artery involved: extracranial (the part outside the skull ...
Arterial dissections become life-threatening when growth of the false lumen prevents perfusion of the true lumen and the related end organs. For example, in an aortic dissection, if the left subclavian artery orifice were distal to the origin of the dissection, then the left subclavian would be said to be perfused by the false lumen, while the left common carotid (and its end organ, the left ...
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [1] A male and a female cadaver were cut into thin ...
Anatomical terminology. [edit on Wikidata] The crus of diaphragm (pl.: crura), refers to one of two tendinous structures that extends below the diaphragm to the vertebral column. There is a right crus and a left crus, which together form a tether for muscular contraction. They take their name from their leg-shaped appearance – crus meaning ...
Cervical artery dissection has been noted to be a common cause of young adult strokes, with some sources indicating a prevalence of up to 20% in this young adult population with annual incidence rates between 2.6 and 2.9 per 100,000, although these incidences may be misleading with true incidences being higher because clinical presentations can vary, many being minor or self-limited, and thus ...
Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography. Surface anatomy deals with anatomical features that can be studied by sight, without dissection. As such, it is a branch of gross anatomy, along with endoscopic and ...
The arbor vitae / ˌɑːrbɔːrˈvaɪtiː / (Latin for " tree of life ") is the cerebellar white matter, so called for its branched, tree-like appearance. In some ways it more resembles a fern and is present in both cerebellar hemispheres. [ 1 ] It brings sensory and motor information to and from the cerebellum.
Total mesorectal excision. Total mesorectal excision (TME) is a standard surgical technique for treatment of rectal cancer, first described in 1982 by Professor Bill Heald at the UK's Basingstoke District Hospital. [1][2] It is a precise dissection of the mesorectal envelope comprising rectum containing the tumour together with all the ...
