Although studies into the structures is causing some scientists to question human understanding of them, mammillary bodies primarily act as relays for impulses that travel through the brain. Additionally, the bodies appear to be very important in forming and recalling memories. Destruction or injury to these portions of the brain is often associated with amnesia.Know More
The mammillary bodies combine with the diencephalon to form a portion of the limbic system. The mammillary bodies form the terminals of the anterior arches of the fornix. They carry electrical impulses from the brain and thalamus through to the spinal cord and on to the rest of the nervous system. This explains why these structures are often associated with sensory control and movement.
The mammillary bodies each contain two sets of nuclei. One set is called the medial nuclei, and the other set is called the lateral nuclei. Despite long-held beliefs about the mammillary bodies and their functions in memory, a 2010 study in “Neuropsychologia,” by SD Vann, found that the two different sets of nuclei have different functions. While Vann did not investigate the lateral mammillary bodies, Vann did find that the medial nuclei were important for spatial memory development and recall in rats.Learn more about Glands & Hormones
The Cowper's glad, also known as the bulbourethral gland is responsible for producing pre-ejaculate fluid in the male reproductive system, as noted by Healthline. The purpose of the pre-ejaculate fluid is to make the environment of the urethra more hospitable for sperm and thus aid in reproduction.Full Answer >
The Society for Endocrinology describes the function of adrenocorticotropic hormone, or ACTH, as the stimulation necessary to release cortisol. ACTH also helps stimulate the body to produce higher levels of adrenaline and noradrenaline.Full Answer >
Among the functions attributed to sebum in humans are the protection of the skin from UV rays, the inhibition of harmful microorganisms on the skin, the delivery of antioxidants to the skin surface and the creation of a moisture barrier to prevent excess water from passing through the skin. Though it performs many functions, science does not yet have a complete understanding of the role of sebum in the body.Full Answer >
The major function of the thyroid gland is to produce thyroid hormones, according to HowStuffWorks. One hormone is called thyroxine and the other triiodothyronine, or T4 and T3. Together, they regulate the growth and development of nearly every system in the body.Full Answer >
