what is a pineal gland and what happens when you open it?
I read something about a pineal gland and people opening it. Why do they want to open it, what is it, and what happens when it is open?
The pineal gland is a small endocrine gland in the brain that produces melatonin, a hormone that affects the modulation of wake/sleep patterns and photoperiodic (seasonal) functions.
Sometimes pineal glands can form cysts. Smaller cysts (less than 0.5cm) are usually asymptomatic, but larger ones can cause painful headaches, affect your vision, make you dizzy, and cause a buildup of pressure in your brain. Sometimes the best course of action is to undergo endoscopic surgery to remove the cyst, which can resolve the symptoms.
It's part of the epithalamus in the middle of your brain. It manufactures and secretes melatonin which effects sleeep/wake cycles (circadian rhythms). The pineal gland is reddish-gray and about the size of a grain of rice (5-8 mm) in humans, located just rostro-dorsal to the superior colliculus and behind and beneath the stria medullaris, between the laterally positioned thalamic bodies
From the second and third vertabrae, the superior cervical ganglion supplies its sympathetic innervation
There is also a parasympathetic innervation from the otic nerve
