HYPOTHALAMUS

    About the size of a pearl, the hypothalamus directs a multitude of important functions in the body. Located in the diencephalon region of the fore brain, the hypothalamus is the control center for many autonomic functions of the peripheral nervous system. Connections with structures of the endocrine and nervous systems enable the hypothalamus to play a vital role in maintaining homeostasis. Homeostasis is the process of maintaining bodily equilibrium by monitoring and adjusting physiological processes. Blood vessel connections between the hypothalamus and pituitary gland allow hypothalamic hormones to control pituitary hormone secretion. Some of the physiological processes regulated by the hypothalamus include blood pressure, body temperature, cardiovascular system functions, fluid balance, and electrolyte balance. As a limbic system structure, the hypothalamus also influences various emotional responses. The hypothalamus regulates emot...

PENGUINS

  Penguins are feathered birds , but they are, differently feathered. Because they spend so much of their lives in the water, they keep their feathers slicked down and waterproofed. Penguins have a special oil gland, called a preen gland, that produces a steady supply of waterproofing oil. A penguin uses its beak to apply the substance to its feathers regularly. Their oiled feathers help keep them warm in the frigid waters, and also reduce drag when they're swimming. Like other birds, penguins molt old feathers and regrow replacements. But instead of losing some feathers at different times throughout the year, penguins do their molting all at once. This is known as a catastrophic molt. Once each year, the penguin bulks up on fish to prepare for its annual changing of the feathers. Then, over a period of a few weeks, it molts all of its feathers and grows new ones. Because its feathers are so vital to its ability to survive in cold waters, it makes sense for a p...
