Sexual Dimorphism in Brain Structure
[ send me this essay ]
A 10 page discussion of the differences which exist between males and females in terms of brain structure. There is no contesting the fact that there are structural differences between male and female brains. These differences are found in numerous species of vertebrates and, in fact, in human beings themselves. Just what these differences mean, however, is a subject of considerable debate. While brain size in particular seems to be linked to greater intelligence for many species, no definitive proof exists that human males are any more intelligent than human females. The manner in which males and females process information, however, does differ significantly. Bibliography lists 10 sources.

Skeletal Muscle Contraction and Structure
[ send me this essay ]
A 5 page paper describing muscle function and structure. There are several theories of the action of muscle contraction. Though at least two of these theories appear to be more than plausible, the precise mechanism by which muscles contract still is not absolutely known. What is known, however, is that the entire process is biochemically controlled and tightly choreographed to produce the desired result. Bibliography lists 4 sources.

Stress & Memory/Article Critique
[ send me this essay ]
A 10 page research paper that offers an article critique research performed by Elzinga and Roelofs (2005), which explored the “effects of stress-induced cortisol elevations on working memory” and whether or not this effect is dependent on the level of adrenergic activity, as measured by sympathetic autonomic activation) (Elzinga and Roelofs, 2005, p. 99). The various components of this research are summarized and discussed. The paper also includes a literature review, in appropriate sections of this discussion, that further explores research on this topic. Bibliography lists 10 sources.

Taming Fat
[ send me this essay ]
An 8 page paper discussing some of the discoveries associating obesity with genetic predisposition. Obesity is approaching “epidemic” levels in the United States, and along with its increase also are rises in incidence of diabetes. Diabetes’ high blood sugar damages organs, including the heart, kidneys and eyes. Diabetes is in itself a risk factor for heart disease, and we have known for years that high serum cholesterol (i.e., fat) constitutes a separate risk factor for heart disease as well. The purpose here is to trace fat’s progress and examine some of the factors resulting in some people being lean, others becoming obese while practicing very similar dietary habits. Bibliography lists 7 sources.
