Tuber cinereum[edit | edit source]
The tuber cinereum is a part of the hypothalamus, located in the brain. It is a grayish, protuberant area situated between the optic chiasm and the mammillary bodies. The tuber cinereum is an important structure involved in the regulation of various physiological processes, including the release of hormones from the pituitary gland.
Anatomy[edit | edit source]
The tuber cinereum is part of the ventral surface of the hypothalamus. It is composed of gray matter and is located in the median eminence, which is the part of the hypothalamus that connects to the pituitary gland via the pituitary stalk, also known as the infundibulum. The tuber cinereum is continuous with the infundibulum and forms the floor of the third ventricle.
Function[edit | edit source]
The primary function of the tuber cinereum is to serve as a conduit for the release of hypothalamic hormones that regulate the anterior pituitary gland. It plays a crucial role in the hypothalamic-pituitary axis, which is essential for maintaining homeostasis in the body. The tuber cinereum is involved in the regulation of body temperature, circadian rhythms, and appetite.
Clinical Significance[edit | edit source]
Lesions or abnormalities in the tuber cinereum can lead to various disorders. For example, damage to this area can result in hypothalamic dysfunction, which may manifest as endocrine disorders, sleep disturbances, or thermoregulatory issues. Additionally, the tuber cinereum is sometimes involved in the development of certain types of brain tumors, such as craniopharyngiomas.
