- A 38-year-old male is upset about his low sperm count and visits a "practitioner" who commonly advertises his miracle cures of sterility. The practitioner is a quack who treats conditions of low sperm count with megadoses of testosterone. Although his patients experience a huge surge in libido, their sperm count is even lower after hormone treatment. Explain why.

An individual has low blood glucose levels—not low enough to cause symptoms, but enough to cause the body to attempt a restoration to normal levels. Describe all processes by which the body induces the increase of blood sugar levels. Your response should include a review of all body cells and structures capable of detecting low glucose levels, the body responses that stimulate glucose production, and all processes for the actual synthesis of glucose. (While this is not a biochemistry class, a thorough discussion of the two major glucose production pathways is expected)

An individual has a higher-than-normal blood volume, due to excess fluids—not high enough to cause symptoms, but enough to cause the body to attempt a restoration to normal levels. Also, it is stipulated that there are no ion imbalances present. Describe all processes by which the body induces the decrease of blood volume. Your response should include a review of all body cells and structures capable of detecting high blood volume, the body responses that stimulate fluid excretion, and all processes for the removal of fluids from the body.

An individual has low blood oxygen levels, due to insufficient numbers of circulating red blood cells. (The erythrocytes are completely healthy; there’s just not enough of them.) Describe the processes by which the body stimulates the production of new erythrocytes. Your response should include a review of all body cells and structures capable of detecting low oxygen levels, the body responses that stimulate erythrocyte production, and the actual synthesis and maturation process in the red bone marrow. In addition, any short-term body processes that compensate for the low blood oxygen levels not involving erythrocyte production should be discussed in detail as well.

a. appearance-conscious sports

b. endurance sports

c. weight-classification sports

d. team sports

What is the purpose of using a 6-lead ECG as opposed to only 1 lead?

Describe the cascade of electrical activity through the heart with a normal sinus rhythm. What controls HR?

What changes are anticipated in an ECG recording in the transition from rest to exercise? What abnormal or pathological changes may occur in the transition from

rest to exercise?

How does body position affect HR? What is occurring physiologically to cause these changes?

Compare the somatic and autonomic nervous systems. Be as detailed as you can in your answer.

What is one similarity and one difference between the motor system that innervate the head and that which controls your body?

Why cone receptors can send information about different frequencies of light?

which skin receptor type is most sensitive to stretching of the skin?

Why is it easier to name a taste in food than a smell in the envirorment?

List and describe the lobes of the cerebrum. What function would be affected if a person were to have damage to the anterior portion of the cerebrum.

During the Ejection Phase:

a. ventricular pressure decreases, while ventricular volume decreases

b. ventricular pressure decreases, while ventricular volume remains the same

c. ventricular pressure decreases, while ventricular volume increases

d. ventricular pressure remains the same, while ventricular volume decreases

e. ventricular pressure remains the same, while ventricular volume also remains the same

f. ventricular pressure remains the same, while ventricular volume increases

g. ventricular pressure increases, while ventricular volume decreases

h. ventricular pressure increases, while ventricular volume remains the same

i. ventricular pressure increases, while ventricular volume increases

Explain the organization of the nervous system. Be as detailed as possible and be sure to include in your answer the divisions, structures or organs involved, direction of the transmission of information where appropriate and specific examples for each type of components within the organizational units.

Marie is 19 years old and has iron-deficiency anemia. She constantly feels fatigued, has headaches, and feels cold most of the time. Marie is within her ideal body weight range and likes to be physically active. She is willing to do whatever it takes to make herself feel better. Marie doesn’t mind including animal products in her diet, but has heard that these foods actually decrease iron absorption. As a result, Marie has identified plant foods that are high in iron and started including them in her diet. At every meal, Marie does not put sugar in her tea because she knows it is not nutrient dense. In addition, when Marie cooks, she uses nonstick stainless steel pans so she doesn’t have to use a lot of fat in her food preparation. Marie usually has a glass of orange juice in between her meals to increase her vitamin C intake and makes sure to take a calcium supplement with her dinner meal. As you can see, Marie is trying to be healthy and decrease the effects of her iron-deficiency anemia. However, there are many things Marie could do to better utilize the iron she does consume. What would you recommend for Marie?

From superficial to interior, describe the composition of a nerve. Be as detailed as possible.
