Does a bigger head mean a bigger brain?

Given two creatures of the same species, the larger of the two will generally be larger in all aspects (lacking mitigating factors such as chemical or hormone suppliments altering or inhibiting their development).  That said, the larger of the specimins may also have a more pronounced skeletal structure to support the additional mass, which would proportionally reduce the amount of room available to actually house the brain.  Thus, the brain would still likely be larger, but not as proportionally as you might expect due to additional skull material.  Of course, brain size has little to do with IQ -- it's all in how the neurons are actually wired up with that being mostly luck and genetics.\n\nFor example, consider purebred Golden Retrievers, where the slope of the dog's forehead (as a mark of the breed) is compacting the brain cavity, thus forcefully reducing the poor dog's brain size.  A less-purebred dog of similar size may not exhibit the same genetic skeletal restriction, and thus have a larger brain cavity filled with a larger brain.  (Noting, once again, that such a dog may still unfortunately be as dumb as a drooling bag of hammers.)

no hole_yer than thine own head.\n\nYes, he was blessed... with more brains than you apparantly

There is no evidence that any of the described traits are favorable.  Larger eyes are might or might not be of any benefit.  Although more area might improve reading, we have not needed more light gathering since Edison invented the light bulb.  The shape of the nose is subject to multiple pressures.  If we all eat processed foods, sharp teeth lose their advantage.  If we eat more steak, no.  Our front teeth will remain flat as it is essential for speech.  Our lips cannot lose much or they alter our speech patterns.  Our pinkies, so long as we use keyboards are unlikely to recede, and as our interactions with technology increase, might increase in functionality.  Larger brains may be possible, but it may be limited by birthing.\n\nI think you received a bigger dose of Science Fiction than Science.  Challenge your teacher to demonstrate the selective pressures that would produce the changes he suggested.

No...man loses his wisdom even thinking about it.  As soon as his little head starts to think - this can be many times in a day - all the energy is drained from his big head and is redirected into his little head. This is the point he  loses reason.  It's interesting to note, the recovery process is almost immediate after he leaves the specific area, drained. That's when he remembers he's married...or whatever

yes it makes as more mamary gland produe more milk the same way bigger brains give u extra intelligence

The normal adult human brain typically weighs between 1 and 1.5 kg (3 lb) and has an average volume of 1,600 cm³. An average male brain has approximately 4% more cells and 100 grams more brain tissue than an average female brain. However, both sexes have similar brain weight to body weight ratios [1]. The mature brain consumes some 20% of the energy used by the body, while the developing brain of an infant consumes around 60%. Such heavy energy usage generates large quantities of heat, which must be continually removed to prevent brain damage.\nAnatomical restraints prevent the human brain from getting even bigger. At birth, an infant's skull is as large as it can be without imperiling the lives of mothers and infants during childbirth. The difficulty experienced by humans in giving birth is nearly unique in the animal kingdom, requiring the head of the emerging infant to be rotated as it passes through the birth canal. Female humans have evolved large pelvic openings to accommodate the birth of large-headed offspring, but at the cost of thinning of the pelvic bones. Bones too thin can no longer bear the mother's weight or the mechanical stresses of walking and running, and a compromised ability to flee dangers may prevent the female from coming of childbearing age. Therefore, brain size and pelvic opening size can be considered an evolutionary trade-off between the ability of females to reach and survive their childbearing and child-rearing years, and their ability to bear big-brained offspring.\nThe human brain is the source of the conscious, cognitive mind. The mind is the set of cognitive processes related to perception, interpretation, imagination, and memories, of which a person may or may not be aware. Beyond cognitive functions, the brain regulates autonomic processes related to essential body functions such as respiration and heartbeat.\n\nExtended neocortical capacity allows humans some control over emotional behavior, but neural pathways between emotive centers of the brain stem and cerebral motor control areas are shorter than those connecting complex cognitive areas in the neocortex with incoming sensory information from the brain stem. Powerful emotional pathways can modulate spontaneous emotive expression regardless of attempts at cerebral self-control. Emotive stability in humans is associated with planning, experience, and an environment that is both stable and stimulating.\nThe following are some commonly held misconceptions of the mind and brain perpetuated through urban legends, mass media, and the promotion of dubious products to consumers (Sala, 1999). A number of practitioners of pseudoscience, New Age philosophies, and mystical or occult practices are known to use some of these ideas as a part of their belief systems (also see popular psychology).\n\nThe human brain is firm and grey: The fresh/living brain is actually very soft, jelly-like and deep red. They do not become firm and grey until they have been preserved with various chemicals/resins. \nHumans use only 10% or less of their brain: Even though many mysteries of brain function persist, every part of the brain has a known function. \nThis misconception most likely arose from a misunderstanding (or misrepresentation in an advertisement) of neurological research in the late 1800s or early 1900s when researchers either discovered that only about 10% of the neurons in the brain are firing at any given time or announced that they had only mapped the functions of 10% of the brain up to that time (accounts differ on this point). \nAnother possible origin of the misconception is that only 10% of the cells in the brain are neurons; the rest are glial cells that, despite being involved in learning, do not function in the same way that neurons do. \nIf all of a person's neurons began firing at once he would not become smarter, but would instead suffer a seizure. In fact, studies have shown that the brains of more intelligent people are less ac

No she's not. Studies have shown that the brain does decrease in size as we age. Very little but measurable.

nope.  left-brained persons are thought to be more analytical (Think math and science oriented personalities)\n\nWhereas, right-brainedpeople are said to be more artistically inclined (think actors, musicians, artists)\n\nDo not be fooled.  Right-brainers are every bit as brilliant as lefters, and you may find many skilled surgeons who are right-brained.   Just as many artistic directors and choreographers may be left-brained.  \n\nIt is always in how you appy yourself to life that counts.

No, the brain size does not change.

The average human head weighs about 7.5% of a person’s body weight. So, if you weigh about 40 kilograms, your head weighs around 3 kilos. If you are a 90-kilogram person, your head weighs about 6.75 kilos.\n\nThere’s a lot in there to make up that mass. Your head has 22 bones — the cranium, which protects the brain, has 8 bones, and the face, 14. So when you get tired of holding your head up high, you know why. It’s heavy!

Technically yes, since a "Tumor" means a "swelling" and a blow to the head can cause a bump. \n\nIf you, however, mean cancerous growth (which is probably what you are talking about), then no.

You'd probably do better with your answers if you had a picture in which your body was not submerged in water.  We could tell better if we could see your body to see if it is proportionate.\n\n\nOkay, you put up a new picture and now I can officially say that in my opinion you have a normal sized head.  Congratulations!
