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).
Each half of the electrochemical cell has an electrode to which the wire for our external circuit is connected. The chemistry takes place at the surface of this electrode. The electrode on the oxidation side is called the anode. The electrode on the reduction side is called the cathode. As a short hand, we simply refer to the two sides of the cell as the anode side and the cathode side.
