Question 1

The primary energy molecule used in living organisms is:
A)NADPH
B)ATP
C)Oxygen
D)Glucose
E)Ribose

Accepted Answer

ATP, or adenosine tri phosphate, is the primary energy molecule used in living organisms. ATP is produced from sugars, (in humans using glucose). Plants use NADPH as an intermediary energy molecule, but not as the primary energy source.

Question 2

Raising the arm sideways is the job of which muscles?
A)Deltoids
B)Pectoralis
C)Trapezius
D)Adductors

Accepted Answer

The job of raising the arm sideways is performed by the deltoids. In particular it is the medial deltoid, which is normally the strongest. The posterior and anterior deltoids twist the arm forward and backward.

Question 3

What is the heel bone called?
A)Patella
B)Calcaneus
C)Plantaris
D)Achilles

Accepted Answer

The heel bone is technically called the calcaneus.
It is the largest of the foot bones. The Achilles tendon attaches to the calcaneus.

Question 4

"I am Commander I. M. Unity; you can call me sir. I coordinate millions of soldiers in the war against infection, inflammation, and allergies. My massive army defends your world from scoundrels like bacteria, viruses, parasites, just to name a few. Currently, an annoyingallergenis invading the eye region. I have dispatched a small team of fighters, from the granulocyte division in response. Alright recruit, what's the official name of this team?"
A)Eosinophils.
B)Basophils.
C)Monocytes.
D)Neutrophils.

Accepted Answer

Basophils, a type of white blood cell, are responsible for the allergic reaction when an allergen invades the body. Basophils secrete histamine and serotonin in response to an allergen. Basophils make up the smallest percentage (0.5 - 1.0%) of the total white blood cell count.

Question 5

What are the channels of energy in the body called?
A)Sen lines
B)Marma lines
C)Meridians
D)All the above

Accepted Answer

The energy channels in the body can be called sen lines, marma lines or meridians.
Sen lines are spoken about in relation to Thai massage. Marma lines are associated with Ayurveda. Meridians are part of Traditional Chinese Medicine.

Question 6

Pain and clicking in the jaw is most likely a result of what?
A)Too much talking
B)TMZ
C)Broken molars
D)None of the above

Accepted Answer

Pain and clicking in the jaw is most likely a result of TMJ disorder.
TMJ stands for temporomandibular joint. The disorder associated with the joint is called TMD. It is brought on by a blow to the jaw, or stress related grinding or clinching of the teeth. Massage is an excellent way to treat TMD.

Question 7

The human body's largest filter; it is part of both the circulatory and digestive systems.
A)The lungs.
B)The kidneys.
C)The liver.

Accepted Answer

Weighing in at approximately three pounds, the liver is the body'slargest filter, and part of both the circulatory and digestive systems. The liver is a vital organ and is responsible for over five hundred life-sustaining functions. The liver is responsible for the filtering and breakdown of all substances, including metabolic wastes and chemicals.Without this function, death will occur within twenty-four hours. Nutrients, vitamins, and fluids are filtered, with some vitamins kept as storage by the liver beforebeing circulated to body tissues. The liver also filters blood, removing old blood cells,bacteria, and other particles. The liver manufactures bile, which is necessary for the digestive process. It also stores energy in the form of glycogen.

Question 8

This organ requires a constant supply of glucose from the bloodstream. Itonly uses glucose as fuel, yet is unable to store its own glucose. Can you Name That Organ?
A)The heart.
B)The lungs.
C)The brain.
D)Ah, one more time?

Accepted Answer

Human brain cells (neurons)require about two times more energy than any other cells in the body. Because the neurons are always active, a constant fuel source is required. Neurons use glucose as their source of energy; however,neurons do not possess glucose storage capabilities. The brain receives its fuel supply by a rich network of blood vessels. When blood glucose levels drop, the brain isaffected long before other symptoms of hypoglycemia (low blood sugar) manifest. Recent studies found glucose levels dropped significantly in students involved in complicated mental tasks; as the glucose level dropped, so did the students' ability to study-an indication of the energy needed for studying!

Question 9

It contains four hollow chambers, made up of specialized cells; it is the driving force in the circulatory system.
A)The heart.
B)The lungs.
C)The arteries.
D)Isn't this game over yet??

Accepted Answer

The heart is made of specialized muscle cells and contains four chambers which blood passes through. Its constant pumping action is what drives the blood circulation through the body. The force of the hearts' pumping action exerts pressure on arterial walls; this is known as blood pressure. The heart pumps approximately five quarts of blood through the body every sixty seconds, and for the average adult beats about 100,000 times a day
