Hyperfunction of the cortex of the adrenal glands
Hyperfunction of the adrenal cortex is a disease that occurs rarely in cats. It is caused by increased synthesis of the hormone cortisone, which leads to metabolic disorders and various pathological processes. The cause may be a tumor of the adrenal glands or pituitary gland.
Symptoms: hair loss, swelling, possible liver failure.
Treatment is usually surgical.

Hyperfunction of the cortex of the adrenal glands
- Hyperfunction of the adrenal medulla
The function of the medulla is enhanced, as a rule, in extreme situations, by the action of nociceptive (from Lat. Possege - to harm) stimuli, when the sympathetic-adrenal system is activated. Sometimes, the basis of the hyperfunction of the adrenal medulla is the formation of a tumor from the cells of the medulla of the adrenal gland or extraadrenal chromaffin tissue - chromaffinoma. It happens more often
- Adrenal insufficiency
1. Give a definition of adrenal insufficiency. Adrenal cortex insufficiency, or Addison's disease, is characterized by reduced production of glucocorticoids and mineralocorticoids by the adrenal glands. The cause of the disease is a pathological process that directly affects the adrenal glands (primary hypoadrenocorticism) or the formation and secretion

The structural basis of steroids is the cyclopenten-perhydrophenanthrane core, consisting of three 6-carbon hexane rings and one 5-carbon pentane ring (D, in Fig. 325-1). Carbon atoms are numbered in sequence, starting from ring A
- Congenital dysfunction of the adrenal cortex (adrenogenital syndrome)
Congenital dysfunction of the adrenal cortex is a group of diseases with an autosomal recessive mode of inheritance, based on a defect in one of the transport proteins involved in the biosynthesis of cortisol by the adrenal cortex. In the pathogenesis of these conditions, a decrease in cortisol synthesis occurs, which leads to hyperproduction of ACTH, the development of adrenal hyperplasia and accumulation
- Acute Insufficiency of the Adrenal Cortex
- A life-threatening condition that develops as a result of a rapid or sudden sharp decline in the functional reserves of the adrenal cortex. Main clinical manifestations With acute adrenal insufficiency, the clinical manifestations increase within a few hours. Patients complain of headache, shortness of breath, severe abdominal pain, vomiting, diarrhea, nervous agitation, convulsions,
- Acute insufficiency of the adrenal cortex.
This is an acute complication caused by acute insufficiency of glucocorticoid and mineralocorticoid production. Distinguish between primary acute adrenal insufficiency (PONH) and acute decompensation of chronic adrenal insufficiency (ODHNN). Causes: POND - hemorrhage in the adrenal glands, heart attack, acute necrosis, trauma, bacterial or viral infections, surgical interventions,
- Hyperthyroidism (hyperthyroidism)
Cause Caused by hyperfunction of the thyroid gland, an increased content of thyroid hormones in the blood plasma. Symptoms Symptoms associated with changes in the function of the pituitary gland: enlargement of the thyroid gland, ophthalmopathy (eye eye), skin changes, including pretibial myxedema (thickening of the skin on the legs and foot, often with itching and burning), muscle weakness. Symptoms associated with
- Hyperfunction of the parathyroid gland
Cause Excessive hormone secretion. Symptoms Demineralization of bone tissue, osteoporosis, bone pain. First aid Need to see a doctor. Blood tests, ECG and computed tomography should be done, strictly follow all medical recommendations. Rejection of bad habits (smoking, alcohol abuse, oily and acute
- Hyperfunction of the anterior pituitary gland
Excessive secretion of somatotropic hormone (growth hormone, growth hormone) is most often observed in eosinophilic pituitary adenoma. Clinically, this is manifested by the development of acromegaly and gigantism. Acromegaly - a disease in people with completed growth, manifested by skeletal imbalances, soft tissues (an increase in the size of the hands, feet, nose, ears, lower jaw), kyphoscoliosis, splenomegaly
- ARCHITECTONICS OF THE BRAIN OF THE BIG HEAD OF THE BRAIN
The doctrine of the structural features of the structure of the crust is called architectonics. The cells of the cerebral cortex are less specialized. than neurons of other parts of the brain; nevertheless, certain of their groups are anatomically and physiologically closely related to one or another specialized parts of the brain. The microscopic structure of the cerebral cortex is not the same in its different parts. These morphological

Large, or terminal, the brain is one of the complex organs of man. The functions of this part of the central nervous system are significantly different from the functions of the trunk and spinal cord. They form the basis of the physiology of higher nervous activity. Under the higher nervous activity I. P. Pavlov meant behavior, activity aimed at adaptability of the organism to changing environmental conditions, on balance

Irritation of the precentral gyrus of the pathological process is accompanied by Jackson epilepsy attacks, expressed in clonic or tonic-clonic convulsions of limited muscle groups corresponding to the irritated part of the cortex: convulsions occur on the side opposite to the pathological focus in the brain and are not accompanied by
- Adrenal glands (problems)
Physical blocking The adrenal glands are the paired endocrine glands, as the name implies, located above the kidneys. They perform several functions: if necessary, they release adrenaline, which activates the brain, accelerates heart rate and mobilizes sugar from the reserve, when the body needs additional energy. They secrete cortisone - a hormone that plays
- Adrenal glands
The adrenal glands are a paired organ and are located extraperitoneally at the upper poles of the kidney. Their weight is 4 g regardless of gender and body weight. The uniqueness of the blood supply to the adrenal glands is that each gland is supplied with the blood of three arteries - branches of the diaphragmatic artery with isolated veins one on each side (the right flows into the inferior hollow, the left into the renal). Cortical
- Adrenal pathology
Adrenal pathology is very diverse, but pheochromocytoma and Addison's disease are more common. Pheochromocytoma - a tumor of the medulla, leads to an increase in blood pressure (adrenaline and norepinephrine), patients die from bleeding in the brain. Addison's disease is caused by the hypofunction of the adrenal cortex, more often with its tuberculous lesion, less often with amyloidosis, cancer metastases,
- Adrenal glands
As already mentioned, the adrenal glands in newborns are relatively larger than in adults. The adrenal medulla of the newborn is very poorly developed and is almost indistinguishable in macroscopic examination. The cortex consists of two layers - the inner one, the darker one, and the outer one, the lighter one. The adrenal medulla is formed from the inner layer over time (A. F.
