With regard to morphology, the initial lesion that characterizes a condition is known as the "primary lesion", and identification of such a lesions is the most important aspect of the cutaneous examination. [30] Over time, these primary lesions may continue to develop or be modified by regression or trauma, producing "secondary lesions". [1]
Retina→Optic nerve→Optic chiasma (here the nasal visual field of both eyes cross over to the opposite side)→Optic tract→Lateral geniculate body→Optic radiation→Primary visual cortex. The type of field defect can help localize where the lesion is located (see picture given in infobox).
Lesions are often classified by their tissue types or locations. For example, a "skin lesion" or a "brain lesion" are named for the tissue where they are found.If there is an added significance to regions within the tissue—such as in neural injuries where different locations correspond to different neurological deficits—they are further classified by location.
[1] [2] It is a secondary condition caused by a primary injury on the opposite hemisphere of the brain. [3] Kernohan's notch is an ipsilateral condition, in that a left-sided primary lesion (in which Kernohan's notch would be on the right side) evokes motor impairment in the left side of the body and a right-sided primary injury evokes motor ...
In neuroanatomy, the primary somatosensory cortex is located in the postcentral gyrus of the brain's parietal lobe, and is part of the somatosensory system. It was initially defined from surface stimulation studies of Wilder Penfield , and parallel surface potential studies of Bard, Woolsey, and Marshall.
Herpetic gingivostomatitis is an infection caused by the herpes simplex virus (HSV). The HSV is a double-stranded DNA virus categorised into two types; HSV-1 and HSV-2.HSV-1 is predominantly responsible for oral, facial and ocular infections whereas HSV-2 is responsible for most genital and cutaneous lower herpetic lesions.
Pre-ulcerative lesion or healed ulcer 1: Superficial ulcer 2: Ulcer deeper to subcutaneous tissue exposing soft tissue or bone 3: Abscess formation underneath, osteomyelitis: 4: Gangrene of part of tissues, limb or foot 5: Gangrene of entire one area or foot
The tumor is an adenocarcinoma derived from a primary lesion in the body of the pancreas. Main article: Liver cancer Most cases are metastases from other tumors , frequently of the GI tract (like colon cancer , carcinoid tumors mainly of the appendix , etc .), but also from breast cancer , ovarian cancer , lung cancer , renal cancer , prostate ...
