The way the human body is mapped out on the brain is very interesting. Most would have expected the body to be organized the same from head to toe and proportional for all areas but that is not the case. Why do you think that certain parts of the body are more represented than others?
Homework Answers
Each part of our body performs some motor or sensory function. However, the complexity and sensitivity of these functions are not equal. Our fingers, for example, are capable of executive extremely fine and specific movements, while our trunks can perform very limited movements. For this reason, parts which involve complex functions have a greater representation in the cortex in comparison to others. The amount of cortical area devoted to our fingers is much higher than that devoted to our trunks, even though our trunks occupy a much larger surface area. Therefore, it is directly related to how richly the region is innervated or the amount of sensory and motor neurons a body region has.

The speed of a nerve impulse in the human body is about 100 m/s.
If you accidentally stub you toe in the dark, estimate the time it
takes the nerve impulse to travel to your brain. (Assume that you
are approximately 1.7 m tall and that the nerve impulse travels at
uniform speed.)

Human Mendelian Traits Like most complex organisms, humans possess an enormous number of genetically inherited characteristics. Some of these are Mendelian in nature, i.e., one gene with two alleles (one true dominant, one true recessive) producing two easily observed traits. You and your partner will evaluate yourselves and each other for your phenotypes, then list the appropriate genotype possibilities. If you are dominant for the trait then assume you are heterozygous unless you know your parents phenotype. 1. Rolling the...

In a lot of properties I’ve worked, there is an ongoing conflict between managers in charge of covering costs and those directly responsible for getting and satisfying guests.” “Like Mark and Pam,” interrupted Damario. “Yes, like Mark and Pam.

One of the more interesting applications of the x test is to examine issues of fairness and cheating in games of chance. Since such games usually involve wagering, there is an incentive for people to try to rig the games, and allegations of missing cards, "loaded" dice, and "sticky" roulette wheels are all too common. Take the example of dice. Most dice used in wagering have six sides, with each side having a value of one, two, three, four, five,...
