Necropsy

Necropsy Examination of a body after death.
RELATED TERMS--------------------------------------
Death
1. The end of life. The cessation of life. (These common definitions of death ultimately depend upon the definition of life, upon which there is no consensus.) 2. The permanent cessation of all vital bodily functions. (This definition depends upon the definition of "vital bodily functions.") See: Vital bodily functions. 3. The common law standard for determining death is the cessation of all vital functions, traditionally demonstrated by "an absence of spontaneous respiratory and cardiac functions." 4. The uniform determination of death.
SIMILAR TERMS--------------------------------------
Necrobiosis Lipoidica Diabeticorum
A skin condition usually on the lower part of the legs. The lesions can be small or extend over a large area. They are usually raised, yellow, and waxy in appearance and often have a purple border. Young women are most often affected. This condition occurs in people with diabetes, or it may be a sign of diabetes. It also occurs in people who do not have diabetes.
Necrophilia
A paraphilia of the stigmatic/eligibilic type in which sexuoerotic arousal and facilitation or attainment of orgasm are responsive to, and not a live partner, but a corpse. There is no reciprocal paraphilic condition except in the make-believe of being dead and copulating in a coffin in preparation for burial - for which there is no technical term.
Necrophilic
The condition of being responsive to or dependent on sexual activity with a cadaver in order to obtain erotic arousal and facilitate or achieve orgasm. In necrophilia, there is an obsession with the state of death, not as there is in sexual homicide with the process of killing.
Necrosis
Dead tissue that surrounds healthy tissue in the body.
Necrotizing enterocolitis
A condition in which part of the tissue in the intestines is destroyed; occurs mainly in under-weight newborn babies; a temporary ileostomy may be necessary.
PREVIOUS AND NEXT TERMS--------------------------------------
Neuron doctrine
The idea that nerve cells are independent biological units.
Nonclassical receptive field
Classical receptive fields are plotted by spots of light or moving stimuli. If a cell responds consistently to that stimulus then the location of that stimulus is said to be within the cells classical receptive field. Activity outside that area can influence a cell's response to the original stimulus. Examples : Motion, Color.
Nucleus of the optic tract (NOT)
Receives input from directionally sensitive cells in the retina. Lesions produce deficits in tracking of moving stimuli.
Null sets
Sets of stimuli which all lead to the same activation of the individual photoreceptor and are thus indiscriminable for that photoreceptor
Nyquist limit
The highest resolvable frequency that can be unambiguously registered by an array of neural elements. A system that encodes spatial patterns at a seires of uniformly spaced sample points can exactly represent sine or cosine gratings of all spacial frequencies up to the Nyquist frequency.
Necropsy
Nephrectomy
Surgical removal of the kidney.
Nephropathy
Any disease of the kidney.
Nephropyelitis
Inflammation of the kidney and renal pelvis often by ascending bacterial infection.
Negative symptoms
Most commonly refers to a group of symptoms characteristic of schizophrenia that include loss of fluency and spontaneity of verbal expression, impaired ability to focus or sustain attention on a particular task, difficulty in initiating or following through on tasks, impaired ability to experience pleasure to form emotional attachment to others, and blunted affect.
Negativism
Opposition or resistance, either covert or overt, to outside suggestions or advice. May be seen in schizophrenia.
