Study Notes
The Pineal Gland & Melatonin
- The pineal gland is situated on the dorsal side of the forebrain.
- The pineal gland secretes melatonin, a hormone with crucial regulatory functions.
- Melatonin plays a significant role in maintaining the body's 24-hour (diurnal) rhythm, commonly known as the circadian rhythm.
- This rhythm governs essential bodily functions like the sleep-wake cycle and body temperature.
- Melatonin's influence extends beyond the circadian rhythm, impacting processes like metabolism, pigmentation, menstrual cycle, and immune system function.
