where is the pineal gland located in the body
Pineal gland The pineal gland is a small endocrine gland in the brain of animals with backbones. The pineal gland produces melatonin, a serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. The shape and size of the gland resemble a pine cone from which it derived its name.[1] The pineal gland is located in the epithalamus, near the center of the brain, between the two hemispheres, tucked in a groove where the two halves of the thalamus join.[2][3] It is also called the conarium, kÃ´narion or epiphysis cerebri. The pineal gland is included among a group of specialized neuroendocrine brain structures called the circumventricular organs.[4]
Lacrimal gland The lacrimal glands are paired, almond-shaped exocrine glands, one for each eye, that secrete the aqueous layer of the tear film. They are situated in the upper lateral region of each orbit, in the lacrimal fossa[disambiguation needed] of the orbit formed by the frontal bone.[1] Inflammation of the lacrimal glands is called dacryoadenitis. The lacrimal gland produces tears which then flow into canals that connect to the lacrimal sac. From that sac, the tears drain through the lacrimal duct into the nose.
