1.  Bone is made up of inorganic mineral salts, with calcium and phosphorous being the most prevalent.
A.
B.
2.  Somatostatin is secreted by which of the following cells found within the islands (islets) of Langerhans in the pancreas?
A.
B.
C.
D.
E.
3.  Which of the following is NOT one of the secondary male sexual characteristics?
A.
B.
C.
D.
E.
4.  The antidiuretic hormone, ADH, promotes the conservation of water by the kidney.  ADH stimulates contraction of muscles in the wall of small arteries thus increasing blood pressure by retaining fluids in the vasculature.  When ADH is not produced in adequate amounts, the daily urine volume increases to 10 to 15 liters instead of the normal 1.5 liters.  This condition is known as diabetes insipidus.
A.
B.
5.  This quiz has over 600 different questions in the question bank and is doing a fine job of helping you advance.Knowing that revenue from the ads on the sides of this page is our main source of income, which of the following is the best way to help keep us afloat and paying the bills?
A.

6.  There are seven cervical vertebrae in the neck.  The first is called the atlas and resembles a bony ring.  It supports the head.  The second is the highly specialized axis.  It has a bony prominence that fits into the ring of the atlas, thus permitting the head to rotate from side to side.  The atlas and the axis are the only named vertebrae; all others are numbered. Each cervical vertebrae has a transverse (or intervertebral foramen) to allow passage of nerves, the vertebral artery, and a vein.  The seventh cervical vertebare has a prominent projection that can easily be felt at the bottom of the neck making it possible for Medical Officers and IDCs to count and indentify the vertebrae above and below it.
A.
B.
7.  The two parietal bones are located behind the frontal bone.  They form the greater part of the right and left sides, and the roof of the skull.  They each have four borders and are shaped like a curved plate.
A.
B.
8.  Which of the following terms refers to the front or along the belly side of the body?
A.
B.
C.
D.
E.
9.  All tissues of the body are continuously bathed in interstitial fluid.  This fluid is formed by leakage of blood plasma through minute pores of the capillaries.  There is a continual exchange of fluids of the blood and tissue spaces with a free interchange of nutrients and other dissolved substances. Most of the tissue fluid returns to the circulatory system by means of capillaries, which feed into larger veins.  Large protein molecules that have escaped from arterial capillaries cannot reenter the circulation through the small pores of the capillaries, however, these large molecules, as well as white blood cells, dead cells, bacterial debris, infected substances, and larger particulate matter can pass through the larger pores of the lymphatic capillaries, and thus enter the lymphatic circulatory system with the remainder of the tissue fluid.
A.
B.
10.  Match the term with its description below
A. Tricuspid valve
A.
B. Bicuspid valve
B.
C. Aortic valve
C.
D. Pulmonary valve
D.
11.  Which of the following statements is FALSE regarding the small intestine?
A.
B.
C.
D.
E.
12.  The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
A.
B.
13.  The heart is a hollow, muscular organ, somewhat larger than the closed fist, located anteriorly on the chest and to the left of the midline.  It is shaped like a cone, its base directed upward and to the right, the apex down and to the left.  Lying obliquely in the chest, much of the base of the heart is immediately posterior to the sternum.
A.
B.
14.  The female gonads are the ovaries, and they produce the female sex hormones estrogen, and progesterone.  Estrogen influences the development and maintenance of the female accessory sex organs and the secondary sex characteristics, and promotes changes in the mucous lining of the uterus (endometrium) during the menstrual cycle. Progesterone prepares the uterus for the reception and development of the fertilized ovum and maintains the lining during pregnancy.
A.
B.
15.  The axial skeleton consists of the skull, the vertebral column, and the thorax.
A.
B.
16.  Axons of the peripheral nerves are commonly enclosed in a sheath called neurilemma, composed of Schwann cells.  Schwann cells wrap around the axon and act as an electrical insulator.  The membranes of the Schwann cell are composed largely of a lipid-protein called myelin, which forms a sheath on the outside of the axon, called white matter. The myelin sheath has gaps between adjacent Schwann cells called Nodes of Ranvier.  Nerve cells without Schwann cells also lack myelin and neurilemma sheaths which are called unmyelinated fibers, or gray fibers.  Myelin is important as it aids in conduction of the electrical impulse.
A.
B.
17.  Which of the following hormones stimulates contractions of the muscles of the uterus, particularly during delivery of a baby?  It also plays an important role in the secretion of milk of the mammary glands of nursing mothers.
A.
B.
C.
D.
18.  The left atrium receives oxygenated blood from the lungs through the four pulmonary veins and pumps it to the left ventricle past the mitral valve.  The left ventricle then pumps the blood to all areas of the body via the aortic valve and the aorta.
A.
B.
19.  Match the salivary gland with its description below
A. Sublingual
A.
B. Submandibular
B.
C. Parotid
C.
20.  Circulation and respiration are controlled primarily by the __________ __________(2 words), located near the center of the brain.

D.
23.  Which of the following is the rest period of the heart?
A.
B.
24.  The middle layer of the eye is the choroid.  It is a high vascular, pigmented tissue that provides nourishment to the inner structures.  Continuous with the choroid is the ciliary body which is formed by a thickening of the choroid and fits like a collar into the area between the Retina and Irish.
A.
B.
25.  Which of the following are airtight membranes that cover the outer surface of the lungs and line the chest wall?  They secrete a serous fluid that prevents friction during movements of respiration.
