Block 1 Chart From Big (up To Section 4) Flashcards
6 causes of congenital anomalies
- genetics
- prenatal infection
- hormones
- vitamin deficiencies
- exposure of fetus to poisons ingested by mother
- parental injury
Aplasia (agenesis)
- cells revert to primitive stages and lose specialization and organization
Dysplasia
Abnormal growth/dev. of organ/part
Anatomic diagnosis
Based on nature and location of lesion
Etiologic diagnosis
- based on basis of the cause
Definitive diagnosis
- based on basis of specific entity involved
Clinical diagnosis
- based on clinical signs seen in live animal
Pressure usually results in what kind of injuries
- mild
- dev. over long time pds
Stenosis
Narrowing of hollow organs
Stricture
Contraction of fibrous CT in organ wall
Effects of electrical injuries
- edema
- hemorrhage
- somatic death due to cardiovasc. & resp. function interference
- burning of tissue
Volvulus
Rotation around base of mesentery
Torsion
Rotation around long axis
Prolapse
Organ pops out natural/artificial orifice
Hernia
Organ pops out natural orifice, but covered w/ skin
Lesions (4) prod. by burns
- blisters
- reddening of tissue
- transepidermal death of cells/ necrosis
- charring
Radiation
- prod. by Ionizing irradiation
- damage extent depends on type, route, and amt. exposure
Light lesions
- sunburn not common in animals
- photosensitization seen
- incandescent light can cause
Photosensitization
- damage of skin due to sunlight causing melanin to produce free radicals
Metaplasia
- one type of cells are replaced with another
Atrophy
Decrease in cell size
Hypertrophy
Increase in cell size
Hyperplasia
Increase in cell #
Serous atrophy of fat
Decrease in amount of fat cells in body depos
