Regulation of Food Intake01:30

Regulation of Food Intake

2.2K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Intracellular Hormone Receptors01:08

Intracellular Hormone Receptors

58.3K
Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell

Chemical Signaling in the Endocrine System

5.9K
A signaling cascade is a series of events that facilitates the transmission of information within or between cells, culminating in a targeted response in the recipient cell. As chemical messengers, hormones are pivotal in initiating and modulating these intricate signaling cascades based on their solubility.
Lipid-soluble hormones, such as steroid hormones, demonstrate an intracellular action. These hormones traverse cell membranes due to their lipid nature. Once inside the target cell, they...

Hormonal Regulation01:40

Hormonal Regulation

47.6K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Hormonal Regulation01:33

Hormonal Regulation

35.5K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Regulation of Hormone Secretion01:19

Regulation of Hormone Secretion

6.0K
Regulation of hormone secretion is a finely tuned orchestration driven by various types of stimuli, encompassing neural, humoral, and hormonal signals. Environmental cues instigate neural stimuli, where action potentials traverse nerve fibers to reach their designated targets. An illustrative scenario is the body's response to stress, wherein the sympathetic nervous system releases epinephrine from the adrenal glands, inducing the well-known 'fight or flight' reaction.
Humoral...

Area of Science:

  • Neuroendocrinology
  • Behavioral Neuroscience

Background:

  • Reproduction relies on hormonal, behavioral, and cognitive processes, often involving the limbic system.
  • Kisspeptin, encoded by the KISS1/kiss1 gene, is a critical reproductive hormone with neuronal populations in the hypothalamus and limbic regions.

Purpose of the Study:

  • To review the expanding roles of kisspeptin signaling beyond reproduction.
  • To explore kisspeptin's influence on behavioral, emotional, and cognitive functions across species.

Main Methods:

  • Review of recent molecular and neural studies on kisspeptin signaling.
  • Analysis of kisspeptin's role in processing sensory cues (olfactory, auditory) and regulating behaviors.

Main Results:

  • Kisspeptin is involved in sexual partner preference, copulatory behaviors, mood, and emotions.
  • Emerging evidence suggests kisspeptin facilitates memory and learning processes.

Conclusions:

  • Kisspeptin signaling is vital for reproductive, emotional, and cognitive control.
  • Understanding kisspeptin's broader roles may inform therapeutic strategies for related disorders.
