SHEET CORE CONCEPT BREAKDOWN
◉ Disease.
Answer: Any abnormal disturbance of the function or structure of
the human body?
◉ Sign.
Answer: An OBJECTIVE manifestation of disease perceptible to the
managing PHYSICIAN
◉ Symptom.
Answer: Any SUBJECTIVE evidence of a disease as perceived by the
PATIENT
◉ Lesion.
Answer: General term used to describe the various TYPES of cellular
change that can occur in response to a disease.
◉ Syndrome.
,Answer: A GROUP of SIGNS and SYMPTOMS that occur together and
characterize a specific abnormal disturbance.
◉ Etiology.
Answer: The study of the cause and ORGIN of disease
◉ Pathogenicity.
Answer: The condition or quality of being pathogenic; the ability to
cause disease.
◉ Prognosis.
Answer: The PREDICTION of course and outcome for given disease.
◉ Idiopathic.
Answer: Having NO identifiable causative factor
◉ Pathogenesis.
Answer: Sequence of event producing cellular changes that
ultimately LEAD to observable changes known as manifestation
◉ Virulence.
Answer: The EASE with which and organism can overcome body
defenses: specifically, the disease evoking severity of a pathogen.
,◉ Acute.
Answer: The QUICK ONSET of disease that lasts a short period of
time (I.e. Pneumonia)
◉ Chronic.
Answer: The SLOW presentation of disease that lasts a very long
time.
◉ 6 categories
Congenital and hereditary
Inflammatory
Degenerative
Metabolic
Traumatic
Neoplastic.
Answer: Diseases are classified into how may categories?
What are the classifications?
◉ Congenital.
Answer: Diseases present AT BIRTH and result from genetic or
environmental factors
, ◉ -Maybe be acquired in utero from maternal infections ,radiation
and drugs
-Caused by abnormalities in the distribution of chromosomes
-Occurs sporadically and cannot be recognized before birth.
Answer: What are the 3 precursors to congenital disease?
◉ Hereditary condition.
Answer: Diseases caused by development disorders GENETICALLY
TRANSMITTED from either parent to child through abnormalities of
individual genes in chromosomes
◉ Derived from ancestors
Inherited disease maybe either dominant or recessive
Amniocentesis.
Answer: What are the precursors for hereditary disease?
◉ Sex-linked-inheritance.
Answer: Genetic abnormality present on one of the two human sex
chromosomes
◉ Autosomal inheritance.
