loose heat through our respiratory surfaces‚ the gut and the skin. Although we can’t control if we lose heat via our respiratory surfaces or the gut‚ the skin is able to control its heat loss. The regulation of body temperature is the role of the hypothalamus. It sends nerve impulses to muscles‚ sweat glands and skin blood vessels to cause changes that counteract the external changes - the skin is the main organ of thermoregulation. Our body also responds to temperature change (heat loss/gain). This

glands within the gastrointestinal tract. The field of medicine that deals with disorders of endocrine glands is endocrinology‚ a branch of the wider field of internal medicine. 1. The hypothalamus and pituitary gland The pituitary gland is called the “master gland” but it is under the control of the hypothalamus. Together‚ they control many other endocrine functions. These include follicle-stimulating hormone (FSH)‚ which stimulates development and maturation of a follicle in one of a woman’s ovaries

Biological Bases of Behavior Nervous System Made up of neurons‚ which are the nerve cells. These send electrical impulses to one another ( through a process known as firing) telling the body what to do. The parts of a neuron include: Cell Body (a.k.a. soma) – Main part of neuron; contains basic cell parts such as nucleus‚ ER‚ etc.; also has dendrites extending from it. Dendrites – bushy fibers which extend from the soma; receives impulses and directs them towards soma Axon – an extension

quote indicates that he did not like homosexuals very much because he felt that they are all screwed up in the head. Neuroscientist Simon LeVay (1991) reported that a area in the hypothalamus governing sexual behavior is about two times as large in heterosexual men as in homosexual men. This part of the hypothalamus‚ is no larger than a grain of sand‚ is about the same size in heterosexual females as in homosexual men. LeVay admits that his research offers no direct evidence that the brain differences

Abstract: The experiment was done to demonstrate the effect of ADH on the volume and concentration of urine in order to demonstrate the control of ADH over blood plasma osmolarity. Since non-invasive methods were preferred the volume and concentration of urine was used in place of drawing blood. The results that we our anticipating are that ADH levels in the group of subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all
