Pathology
is the medical discipline that describes conditions typically observed during a disease state, whereas physiology is the biological discipline that describes processes or mechanisms operating within an organism.
What is the difference between physiology and pathology?
Pathology describes the conditions during the diseased state
whereas physiology is the discipline that describes mechanisms operating within an organism.
What is the difference between physiological and pathological adaptation?
Physiological hypertrophy is characterized by normal organization of cardiac structure and normal or enhanced cardiac function, whereas pathological hypertrophy is commonly associated with upregulation of fetal genes,
fibrosis, cardiac dysfunction and increased mortality
.
What does pathological mean?
1 :
of or relating to pathology pathological research
A pathological examination led to the diagnosis. 2 : altered or caused by disease pathological changes in the body also : indicative of disease pathological symptoms.
What is the difference between physiological and pathological atrophy?
Atrophy is the general physiological process of
reabsorption
and breakdown of tissues, involving apoptosis. When it occurs as a result of disease or loss of trophic support because of other diseases, it is termed pathological atrophy, although it can be a part of normal body development and homeostasis as well.
What are physiological diseases?
A physiological disorder is
an illness that interferes with the way that the functions of the
.
body are carried out
. Examples are: Diabetes, Alzheimer’s, Parkinson’s, rheumatoid arthritis, asthma, leukemia, coronary heart. disease, any form of cancer.
Is pain physiological or pathological?
Pain may be broadly classified into
physiological and pathological pain
. Nociceptive and inflammatory pains are physiological pain states, as they are protective and adaptive, whereas pathological pain is nonprotective and maladaptive. Nociception is the result of suprathreshold stimulation of peripheral nociceptors.
What is an example of hypertrophy?
Hypertrophy is an increase in the size of cells (or tissues) in response to various stimuli. A typical example is
muscular hypertrophy in response to exercise
. Exercise stimulates skeletal and cardiac muscle fibers to increase in diameter and to accumulate more structural contractile proteins.
What is pathological disease?
Definition:
Abnormal anatomical or physiological conditions and objective or subjective manifestations of disease
, not classified as disease or syndrome.
Which situation causes hypertrophy?
Physiologic hypertrophy: Occurs due to
a normal stressor
. For example, enlargement of skeletal muscle with exercise.
What is an example of pathological?
Typical examples include
cervical smear, sputum and gastric washings
. Forensic pathology involves the post mortem examination of a corpse for cause of death using a process called autopsy. Dermatopathology concerns the study of skin diseases.
What is meant by pathological features?
The pathological features are
a consequence of the progressive accumulation of glucosylceramide within mononuclear phagocytes
. A wide variety of gross and microscopic anatomical changes are seen, primarily in the bone marrow, liver, spleen and bones.
What are some examples of pathological conditions?
- Diseases.
- Animal Diseases.
- Bacterial Infections and Mycoses.
- Cardiovascular Diseases.
- Congenital, Hereditary, and Neonatal Diseases and Abnormalities.
- Digestive System Diseases.
- Disorders of Environmental Origin.
- Endocrine System Diseases.
What are the pathological causes of atrophy?
Pathologic atrophy is seen with
aging, starvation, and diseases such as Cushing disease
(because of taking too much medicines called corticosteroids). Neurogenic atrophy is the most severe type of muscle atrophy. It can be from an injury to, or disease of a nerve that connects to the muscle.
What are the two types of atrophy?
Muscle atrophy is the wasting or loss of muscle tissue. There are two types of muscle atrophy:
disuse and neurogenic
. The first type of muscle atrophy is disuse atrophy and occurs from a lack of physical exercise. In most people, muscle atrophy is caused by not using the muscles enough.
What are the symptoms of muscle wasting?
- Balance problems, difficulty walking, and falls.
- Difficulty with speaking and swallowing.
- Facial weakness.
- Gradual difficulty walking and speaking, memory loss, tingling or weakness of extremities.
- Impaired balance and coordination.
- Loss of muscle coordination.
