What are the functions of the arachnoid mater and the pia mater in the brain?
Q. What are the functions of the arachnoid mater and the pia mater in the brain? Not together, but there separate functions. Thanks!

A. The brain has 3 coverings called the meninges. The outer most is the dura mater, the middle the arachnoid mater and the inner the pier mater. All three covers have the purpose of protecting the brain against infection and injury. The cerebral spinal fluid can be found in a tiny gap between the arachnoid mater and the pia mater called the sub arachnoid space. This fluid acts as a shock absorber for the brain, to prevent injury from the brain hitting against the bony inside of the skull. The fluid also carries nutrients and wast products. Lumbar punctures are done by putting a fine needle into the sub arachnoid space and with drawing a tiny amount of fluid for examination. The pia mater is the only covering that is flush with the… [cont.]

A. Chromosomes provide the hereditary information for an organism and contains DNA (genes/alleles). Centromere is the condensed area where the sister chromatid joins to the chromosome during replication - is also used to allow crossing-over of homologous chromosomes. Spindle fibres are the fibers that radiate from two poles and meet at the equator in the middle (I think they are used to move the chromosomes around so they can be separated and gametes can be formed, but I'm unsure of this).

A. The cutaneous membrane (skin) and its accessory structures (hair, scales, feathers, nails, exocrine glands) make up the integumentary system. There are three layers of skin: Epidermis Dermis Subcutaneous tissue Below the dermis, the subcutis acts to protect underlying muscles, tissues, and other organs. Hair on the surface of the skin helps maintain body temperature and filter out harmful particles. Cutaneous glands include: Sweat glands (also known as sudoriferous glands) - excrete sweat to regulate temperature Sebaceous glands - oil-producing glands that keep skin and hair moist and soft Ceruminous glands - glands of the ear canal that produce earwax Mammary glands - milk-producing glands located in the breasts.

What functions does the left side of the human brain control?
Q. My son was born premature and had to stay in the nicu for about 2 months. When he was about a week or two old the doctors informed us that he had a grade 4 bleed in the left side of his brain.He never had any swelling, and it eventually went away. He is now 5 months old, and has hit his developemental milestones for his corrected age (2 months) and some for his actual age. I'm just wondering what kind of damage the bleed could have done, and what functions the left side of the brain controls?
Asked by <3His forever<3 - Mon Jun 7 02:33:06 2010 - - 1 Answers - 0 Comments

A. The left side of the brain controls the right side of the body but your son might not have any permanent damage from the bleeding. Children that young are very resilient and the brain has a way of healing itself and/or switching a function of one part to another. At this early age about all you can do is wait and see and have his doctors keep a close eye on his development.

Use generating functions to find the number of ways to choose a dozen bagels from three varieties?
Q. Use generating functions to find the number of ways to choose a dozen bagels from three varieties egg, salty, and plain if at least two bagels of each kind but no more than three salty bagels are chosen. Please show your work. Thanks in advance!
Asked by Jean-Francois - Sat Jan 26 23:22:21 2008 - - 1 Answers - 0 Comments

A. Hi, since there must be 2 bagels of each kind, the maximum number of egg and plain bagels are 8. so their generating functions are x^2 + x^3 + ... + x^8. on the other hand, the generating function for salty bagel is just x^2 + x^3. So you want to find the coefficient of x^12 in f(x) = (x^2 + x^3 + ... + x^8)^2 * (x^2 + x^3). (x^2 + x^3 + ... + x^8)^2 is easy to expand since it follows a symmetric pattern. (x^2 + x^3 + ... + x^8)^2 = x^4 + 2x^5 + 3x^6 + 4x^7 + 5x^8 + 6x^9 + 7x^10 + 6x^11 + 5x^12 + ... 2x^15 + x^16 so f(x) = (x^4 + 2x^5 + 3x^6 + 4x^7 + 5x^8 + 6x^9 + 7x^10 + 6x^11 + 5x^12 + ... + 2x^15 + x^16) * (x^2 + x^3) you can then distribute the expansion to x^2 + x^3. f(x) = x^2 (x^4 + 2x^5 + 3x^6 + 4x^7 + 5x^8 + 6x^9 + 7x^10 +… [cont.]

What are the functions of the precentral and postcentral gyrus?
Q. Doesn't need to be super complex, but what are the basic functions?
Asked by floridaguy - Mon Oct 15 12:00:01 2007 - - 1 Answers - 0 Comments

A. In the frontal hemisphere of the cerebrum, the precentral gyrus is the main motor centre ie it initiates the onset of movements, mainly produced by contraction of skeletal muscle. These impulses pass via the internal capsule to the spinothalamic tract in the spinal cord, both parts of the pyramidal system. THe postcentral gyrus is the principal somatic (of the body) sensory area. It is the end-point of sensory information from the skin (for touch, pain, pressure and temperature sensation) and from the spindle organs in the joints (for position sense). Hope this helps.

A. sin, tan, cosec, cot. You can find explanations by entering 'reference angle' in a search engine. Normally the sites deal only with sin, cos and tan. One such site is: As cosec x = 1 / sin(x), sec(x) = 1 / cos(x), cot(x) = 1 / tan(x), the sign for: cosec matches that for sin, sec matches that for cos, cot matches that for tan.

Asked by sha sha - Wed Nov 22 06:22:46 2006 - - 1 Answers - 0 Comments

A. I'd say price has ONE function, but serves several purposes. Prices are there to ensure that supply equals demand for any product or service. This is useful for several reasons: (1) it limits the demand of scarce products or commodities to sustainable levels -- which would otherwise have had to be done throught inefficient rationing schemes; (2) in case of scarcity the price signal induces producers to increase their capacity because rising prices means rising profitability; and (3) relative price changes send important signals to decision makers about changing preferences -- which would otherwise (think Soviet Union!) have had to be handled through incredibly cumbersome planning procedures.

What common principles unite the diverse functions of membranes?
Q. One of the larger facets of modern zoology can be described as "membrane biology." What common principles unite the diverse functions of membranes?
Asked by LD - Sun Jan 10 22:23:08 2010 - - 1 Answers - 0 Comments

A. Membranes usually consist of a phospholipid bilayer, hydrophillic phosphate heads facing out (towards water/cytoplasm) hydrophobic tails in (away from water/cytoplasm). This causes a ring (membrane) formation due to the natural tendency of the hydrophobic tails to find a position in which they are not exposed (which only happens when the ring is completed). Membranes function as barriers that keep organelles within the cell, provide structure, allow diffusion of specific chemicals and serve as an anchoring point for proteins which actively transmit chemicals that are too large or flow against the concentration gradient. I was unsure which information you wanted so, there's a generalization.
