The pineal gland is an endocrine gland, like the pituitary gland, thyroid gland, adrenal gland, and pancreas. Like other endocrine glands, it secretes a hormone -- in this case melatonin.The pineal gland was the last endocrine gland to have its function unveiled, partially because of its small size, roughly that of a pea, and its structural uniformity.he pineal gland is located near the center of the brain. Shamans have claimed that the pineal gland is a connection between the earthly realm and a spirit world. Endocrine glands include the adrenal gland. The pineal gland secretes melatonin, which promotes sleep.
The figure is an edge view of three charged metal electrodes: 1. Draw a graph of versus over the region. Hint: Assume that at. [along the y-axis, it's V(kV). along the x-axis it's x(cm).
In the example above, it was shown that the driving force for the flow of current and thus the corrosion is the difference in electrode potential. The electrode potential of a metal is an indication of the tendency of the metal to dissolve and corrode in a certain electrolyte.
