Detailed explanation-1: -Your pineal gland’s main job is to help control the circadian cycle of sleep and wakefulness by secreting melatonin. The pineal gland is shaped like a tiny pinecone, which is how it got its name (“pine”-al gland). However, it is pronounced “pin-ee-uhl.”
Detailed explanation-2: -The main function of the pineal gland is to receive information about the state of the light-dark cycle from the environment and convey this information by the production and secretion of the hormone melatonin.
Detailed explanation-3: -Your pineal gland secretes the highest levels of melatonin during the night and minimal amounts during the day.
Detailed explanation-4: -The pineal gland is a very small gland in the centre of the brain shaped like a pine cone, which is where it gets its name. It is part of the endocrine system. It produces a hormone called melatonin.
Detailed explanation-5: -It is a pinecone-shaped small gland located in the middle of the human brain in between the two hemispheres in an area called epithalamus. It was once known as “the third eye”. It is the major site for melatonin secretion, which regulates the body’s internal clock (Circadian rhythm).
