Why are tropic hormones so called?
Tropic hormones are named for their action on other endocrine glands. Their primary function is to stimulate the secretion of hormones by target glands in a sequence known as the hypothalamic-pituitary-target gland axis. These hormones regulate the activity of other endocrine glands and help maintain homeostasis in the body.
What does the hypothalamic-pituitary axis of the brain do?
The hypothalamic-pituitary axis (HPA) is a critical neuroendocrine system that regulates various physiological processes, including stress response, metabolism, reproduction, and immune function. It involves the hypothalamus releasing hormones that stimulate or inhibit the pituitary gland, which in turn secretes hormones that affect other endocrine glands, such as the adrenal glands and thyroid. This axis serves as a communication pathway between the nervous system and the endocrine system, ensuring the body maintains homeostasis and responds appropriately to internal and external stimuli.
What do releasing hormones do?
Releasing hormones are produced by the hypothalamus to stimulate the pituitary gland to release its own hormones. These releasing hormones regulate the secretion of hormones from various endocrine glands in the body, helping to maintain proper hormonal balance and functionality.
What are the signals received from the hypothalamus called?
The signals received from the hypothalamus are typically referred to as hypothalamic hormones or neurohormones. These signals can include various releasing and inhibiting hormones that regulate the pituitary gland's function, influencing processes such as growth, metabolism, and stress responses. Key examples include thyrotropin-releasing hormone (TRH) and gonadotropin-releasing hormone (GnRH).
How does hypothalamus control the pituitary?
The hypothalamus controls the pituitary gland through the release of hypothalamic-releasing hormones and inhibiting hormones. These hormones travel through a network of blood vessels to the pituitary gland and stimulate or inhibit the release of various hormones from the pituitary. This way, the hypothalamus regulates the endocrine functions of the pituitary gland.
What is the region of the brain when functions as an endocrine gland by producing hormones that influence the activities of the pituitary gland?
Hypothalamus, it links the nervous system to the endocrine system via the pituitary gland (hypophysis). P.S. - It secretes hypothalamic tropic factors (hypothalamic hormones - neurohormones, often called hypothalamic-releasing hormones) to the anterior lobe of the pituitary gland by way of a special capillary system, called the hypothalamic-hypophysial portal system.(Courtesy: Wikipedia - the free encyclopedia)

What is the function of the ventral hypothalamic neurons?
control secrection of the thyroid stimulating hormone ( TSH)
What is the function of the tuberohypophyseal tract?
it allows humoral factors in hypophyseal portal circulation or systemic circulation to access hypothalamic nuclei via retrograde axonal transport (i.e. feedback regulation of pituitary hormones)

The function of growth hormones is the stimulate growth in the body

What is the general function of the Reproductive system?
The general function of the reproductive system is to produce, store, and transport gametes for fertilization and to support the development of offspring. It also involves the production of sex hormones that regulate sexual development and behavior.
Is the hypothalamic-hypophyseal tract partly contained in the infundibulum?
Yes, the hypothalamic-hypophyseal tract passes through the infundibulum, which is a funnel-shaped extension of the hypothalamus. This tract connects the hypothalamus with the posterior pituitary gland, allowing for the release of hormones such as oxytocin and vasopressin directly into the bloodstream.
What is hypothalamic pituitary testicular axis?
The hypothalamic-pituitary-testicular (HPT) axis is a complex system of hormonal regulation that controls male reproductive function. It begins with the hypothalamus releasing gonadotropin-releasing hormone (GnRH), which stimulates the pituitary gland to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones then act on the testes, promoting testosterone production and spermatogenesis. This axis is crucial for the development of male secondary sexual characteristics and overall reproductive health.
