Pineal Gland By Kacie Andrews & Cheyanne Schreiner Period 7B
Where is it located? The Pineal Gland is located within diencephalon, near the epithalamus. Right beneath the section of the brain that relays sensory information to different sections of the brain.
What hormones does it produce? The main hormone the Pineal gland produces is the hormone melatonin.
What effect do these hormones have on the body? Melatonin helps regulate your internal clock. It affects your sleep-wake cycles.It been known to affect reporductive function and a persons biological clock. This hormone is also the cause of jet lag.
Why are they important in maintaining homeostasis? Homeostasis is a stable internal environment in the body.Hormones are secreted through the Endocrine system. If this system is disrupted, the endocrine system secretes it hormones to reach a state of homeostasis(normal state). After our body reaches this point, the endocrine system stops secreting these hormones. Which helps maintain Homeostasis.
Feedback Mechanisms The source of the human body’s circadian rhythms lies in the suprachiasmatic nuclei (SCNs). In day SCN greatly decreases the production of melatonin created by the Pineal Gland. And increases at night.
Releasing Hormones The glands that secrete the hormones are ductless. This means that the hormones are released directly into the bloodstream. And travel elsewhere into the body.
What if the gland stopped working? If the Pineal Gland stopped working, it would stop melatonin production, causing your weight to fluctuate. This is a problem for those who are [diabetic]. If the there is too much melatonin production, it can cause conditions such as insomnia.
Pineal Gland tumor Symptoms: mainly caused by a blockage of cerebrospinal fluid flow, problems with eye movement pathways, Headache, nausea, vomiting, and double vision are all common. Pineal Gland tumors can often be dangerous.But it rarely spreads elsewhere in the body. And 10% to 20% of tumors, mainly pineoblastoma, have potential to spread through the cerebral fluid.
Can it be medically corrected? There is currently only medication to aid against sleep loss. If there is a chance you have any form of a Pineal tumor. There is radiation therapy & surgery to help. Yeah so thats pretty much it…
