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).
The anode is the electrode where oxidation occurs and electrons are lost. The cathode is where reduction takes place and electrons are gained. These reactions don't occur separately; they must work together in a reduction-oxidation reaction.For this next section, let's assume the electrodes are zinc and copper.o determine the voltage of any cell, subtract the electrode potential of the anode from that of the cathode and you get the electrode potential of the cell, or voltage. Eo cell = Eo cathode-Eo anode. Corrosion is when metal is gradually destroyed through chemical reactions, and it is a real problem in our daily lives.
