Study Notes
Hypothalamus
Neurotransmitters
- Produces and responds to various neurotransmitters, including:
- Acetylcholine (ACh)
- Norepinephrine (NE)
- Serotonin (5-HT)
- Dopamine
- Releases neurotransmitters to regulate various physiological processes
Body Temperature
- Regulates body temperature through:
- Heat production (shivering)
- Heat loss (sweating)
- Maintains a set point temperature of around 37°C (98.6°F)
- Receives input from temperature sensors in the skin and hypothalamus
Hormone Regulation
- Produces and regulates various hormones, including:
- Releasing hormones (e.g., thyrotropin-releasing hormone, corticotropin-releasing hormone)
- Inhibiting hormones (e.g., somatostatin)
- Regulates the release of hormones from the pituitary gland, which in turn regulates other endocrine glands
Hunger And Thirst
- Regulates feeding behavior and energy homeostasis through:
- Hunger and satiety centers
- Response to leptin and insulin
- Regulates thirst and water intake through:
- Osmoreceptors and baroreceptors
- Regulation of vasopressin (ADH) release
Sleep And Wakefulness
- Regulates the sleep-wake cycle through:
- Circadian rhythm regulation
- Interaction with the suprachiasmatic nucleus (SCN)
- Produces and responds to sleep-promoting neurotransmitters, such as:
- Adenosine
- Melatonin
