A pinealoma is a tumor of the pineal gland, a part of the brain that produces melatonin. If a pinealoma destroys the cells of the pineal gland in a child, it can cause precocious puberty . Signs and symptoms
Pineocytoma, is a rare, benign, slowly growing tumor of the pineal gland. The pineal gland is a small endocrine gland close to the center of the brain that secretes melatonin into the bloodstream. Pineocytomas can cause pressure and fluid build-up in the brain. They are more common in adults. Symptoms include vision problems, nausea, vomiting ...
The human pineal gland grows in size until about 1–2 years of age, remaining stable thereafter, [20] [21] although its weight increases gradually from puberty onwards. [22] [23] The abundant melatonin levels in children are believed to inhibit sexual development, and pineal tumors have been linked with precocious puberty. When puberty arrives ...
Endocrine disorders are often quite complex, involving a mixed picture of hyposecretion and hypersecretion because of the feedback mechanisms involved in the endocrine system. For example, most forms of hyperthyroidism are associated with an excess of thyroid hormone and a low level of thyroid stimulating hormone .
In humans, the major endocrine glands are the thyroid, parathyroid, pituitary, pineal, and adrenal glands, and the (male) testis and (female) ovaries. The hypothalamus , pancreas , and thymus also function as endocrine glands, among other functions.
The scientists discovered that people who had smaller temporalis muscles had a 60 percent higher chance of developing Alzheimer’s disease or dementia. A smaller temporalis muscle size was also ...
The endocrine system is a network of glands and organs located throughout the body. It is similar to the nervous system in that it plays a vital role in controlling and regulating many of the body's functions. Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood.
Endocrine system: communication within the body using hormones made by endocrine glands such as the hypothalamus, pituitary gland, pineal gland, thyroid, parathyroid glands, adrenal glands; Immune system: the system that fights off disease; composed of leukocytes, tonsils, adenoids, thymus, spleen; Integumentary system: skin, hair, nails
