|
Atrophy
|
Cell gets smaller
|
|
|
hypertrophy
|
Cell gets larger, due to adaptation
|
|
|
Hyperplasia
|
increased number of cells
|
|
|
Metaplasia
|
Change in the cell from onen typeof tissue to another,
this is adaptation and can be bad or good |
|
|
Dysplasia
|
Abnormal adaptation
Like an extra finger or how cervical cancer froms |
|
|
Reversible cell injury
|
Cell swelling
Intracellular accumulations |
|
|
Necrosis
|
Irreversible cell injury or death
|
|
|
Different kinds of gang green
|
Dry, wet, Gas
Gas is usually caused by fungis |
|
|
Apoptosis
|
Programmed cell death, very normal expecially on the surface of the skin and the intestianal track. This is also how our body avoids cancer.
|
|
|
Cell aging
|
Cellular basis of aging include, immune function decline, the thymis starts going bad at about 45 and we lose our Killer T cell production, which increases autoimmune disease
|
|
|
Physiologic changes / decreases (Cardiovascular)
|
decreased vessel elasticity
no of heart muscle fibers filling capacity sensitivity of baroreceptors , vein valves |
|
|
Physiologic changes / decreases (Respiratory)
|
chest wall compliance
alveolar ventilation respiratory muscle strength Lung tissue |
|
|
Physiologic changes / decreases (Gastrointestinal)
|
muscular contraction
esophageal emptying bowel motility Production of HCI, enzymes and intrinsic factors Hepatic enzymes Metabolizm Stomach mucosa |
|
|
Physiologic changes / decreases (Neruologic/ sensory)
|
Nerve cells
25% to 45% less of neurons Neurotransmitters Nerve impulse rate taste buds auditory hair cells |
|
|
Physiologic changes / decreases (Musculoskeletal)
|
Muscle mass
Bone demineralization Joint degeneration, erosion and calcification. |
|
|
Physiologic changes / decreases (Immune)
|
T-cell function due to decrease in thymus gland
inflamation response |
|
|
Physiologic changes / decreases (integumentary)
|
subcutaneous fat
elastin atrophy of sweat glands atrophy of epidermal arterioles causing altered temperature regulation |
|
|
Somatic death
|
absence of respirations and heartbeat ... The death of an organism
|
|
|
18 common changes due to aging that are the result of physiological changes
|
Saggy and thin skin - Brittle toenails - Peripheral edema - Decreased body hair -Constantly cold - Fragile bones - Lack of diaphoresis - Decreased activity - Weight loss - Decreased appetite - Constipaiton - UTIs - Increased incontinence - Hypertension - Increased chronic illnesses - Increased acute illnesses- Arthritis - cough/lung congestion
|
|
|
Algor Mortis
|
Pupils dialate and body becomes pale, at this point the body begins to cool 1.5 degrees per hour until reaching poikilothermia (room tempreture)
|
|
|
Poikilothermia
|
Body is cold or at least the tempreture of environment
|
|
|
Liver Mortis
|
Gravity pulls all the blood toa dependant position usually within 4-6 hours
|
|
|
Rigor mortis
|
ATP stops production and stiffening sets in at about 6-24 hours
|
|
|
Post mortem autolysis,
|
body begins to bloat and begin aoutolysis, after 24 hours
|
|
|
Failure of the NA pump
|
will cause cell swelling and it can be reversed if problem is treated
|
|
|
When the Pancrease is injured what is released into the blood
|
Amylases
|
