An abnormal increase in the size of an organ is
- A.
Atrophy
- B.
Hypertrophy
- C.
Dystrophy
- D.
Hypothrophy
- E.
Visceral
Correct Answer
B. HypertrophyExplanation
Hypertrophy refers to an abnormal increase in the size of an organ. This can occur due to various factors such as increased workload, hormonal stimulation, or increased demand for the organ's function. It is characterized by an increase in the size of individual cells within the organ, resulting in an overall increase in organ size. Atrophy, on the other hand, refers to a decrease in organ size, while dystrophy refers to abnormal development or degeneration of tissues. "Hypothrophy" is not a recognized term, and "visceral" refers to the internal organs of the body.Rate this question:

An abnormal decreases in the total number of WBC's is known as
- A.
Leukocytosis
- B.
Leukemia
- C.
Leukosis
- D.
Leukopenia
- E.
Anemia
Correct Answer
D. LeukopeniaExplanation
Leukopenia refers to an abnormal decrease in the total number of white blood cells (WBCs) in the body. This condition can be caused by various factors such as viral infections, autoimmune disorders, certain medications, or bone marrow disorders. It can lead to an increased risk of infections as the body's immune system is compromised due to the low number of WBCs. Leukopenia is different from other options listed in the question. Leukocytosis refers to an abnormal increase in WBCs, leukemia is a type of cancer that affects the production of WBCs, leukosis is not a medical term, and anemia refers to a decrease in the number of red blood cells or hemoglobin in the blood.Rate this question:

- A.
Transverse
- B.
Coronal
- C.
Frontal
- D.
Sagittal

Horizontal
Correct Answer
D. SagittalExplanation
The plane that divides the body into right and left halves is the sagittal plane. This plane passes vertically through the body, dividing it into two equal halves along the midline. The term "sagittal" is derived from the Latin word "sagitta," meaning arrow, as the plane resembles an arrow slicing through the body from front to back. The other options, transverse, coronal, frontal, and horizontal, do not divide the body into right and left halves, but rather into different sections or planes.Rate this question:

A. AsthmaExplanation
Wheezing is a classic sign of asthma. Asthma is a chronic respiratory disease characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, shortness of breath, and chest tightness. Wheezing occurs when there is a constriction of the airways, causing a high-pitched whistling sound during breathing. Therefore, wheezing is a common and recognizable symptom of asthma.Rate this question:

Organ of Corti
Correct Answer
B. Tympanic membraneExplanation
The eardrum, also known as the tympanic membrane, is a thin, cone-shaped membrane that separates the outer ear from the middle ear. It plays a vital role in the process of hearing by vibrating in response to sound waves, which then transmit the vibrations to the middle ear bones. The other options listed, such as stapes, cochlea, oval window, and organ of Corti, are all different structures within the ear, but they do not specifically refer to the eardrum.

The vein that returns blood to the heart from areas below the diaphragm is the
- A.
Subclavian vein
- B.
Superior vena cava
- C.
Inferior vena cava
- D.
Axillary vein
- E.
Brachiocephalic vein
Correct Answer
C. Inferior vena cavaExplanation
The correct answer is the Inferior vena cava. The inferior vena cava is a large vein that carries deoxygenated blood from the lower body and returns it to the right atrium of the heart. It receives blood from various veins, including the common iliac veins, renal veins, and hepatic veins. The superior vena cava, on the other hand, returns blood from the upper body to the heart. The other options, subclavian vein, axillary vein, and brachiocephalic vein, are not responsible for returning blood from areas below the diaphragm.Rate this question:

The pacemaker of the heart is the
- A.
Sinoatrial node
- B.
Atrioventricular node
- C.
Cardiac septum
- D.
Bundle of His
- E.
Purkinje fibers
Correct Answer
A. Sinoatrial nodeExplanation
The Sinoatrial node is often referred to as the pacemaker of the heart because it initiates the electrical impulses that regulate the heart's rhythm. Located in the right atrium, it generates an electrical signal that causes the atria to contract and sends the signal to the atrioventricular node, which then relays the signal to the ventricles. This coordinated contraction allows for effective pumping of blood throughout the body. The other options listed are all important components of the heart's electrical conduction system, but the Sinoatrial node is specifically responsible for initiating the heartbeat.Rate this question:

Which electrolyte is important for the activity of the heart muscle
- A.
Chloride
- B.
Sodium
- C.
Acid phosphate
- D.
Potassium
- E.
Bicarbonate
Correct Answer
D. PotassiumExplanation
Potassium is an essential electrolyte for the activity of the heart muscle. It plays a crucial role in maintaining the electrical conductivity of cardiac cells, which is necessary for the proper functioning of the heart. Potassium helps regulate the heart's rhythm and ensures proper contraction and relaxation of the heart muscles. Imbalances in potassium levels can lead to irregular heartbeats and potentially life-threatening conditions such as arrhythmias. Therefore, maintaining adequate potassium levels is vital for the normal activity of the heart muscle.Rate this question:

Pupil dilation
Correct Answer
D. FlexionExplanation
Flexion is the correct answer because it refers to the bending or contraction of a joint or muscle voluntarily. It is a voluntary muscle action that allows movement and flexibility in the body. Breathing, heartbeat, peristalsis, and pupil dilation are involuntary muscle actions that occur automatically without conscious control.Rate this question:

Food is conveyed from the mouth to stomach by the
- A.
Trachea
- B.
Esophagus
- C.
Salivary glands
- D.
Tonsils
- E.
Tongue
Correct Answer
B. EsophagusExplanation
The esophagus is the correct answer because it is the tube that connects the mouth to the stomach, allowing food to pass through. The trachea, on the other hand, is the tube that carries air to the lungs, not food. The salivary glands produce saliva, which helps with the digestion process but does not directly convey food to the stomach. The tonsils are part of the immune system and do not play a role in food transportation. The tongue helps with chewing and swallowing, but it does not directly convey food to the stomach.Rate this question:

An abnormal lateral curvature of the spine is known as
- A.
Kyphosis
- B.
Spondylosis
- C.
Lordosis
- D.
Scoliosis
- E.
Ankylosis
Correct Answer
D. ScoliosisExplanation
Scoliosis is the correct answer because it refers to an abnormal lateral curvature of the spine. Kyphosis is a condition characterized by an excessive outward curvature of the upper back, while lordosis is an excessive inward curvature of the lower back. Spondylosis is a degenerative condition affecting the spine, and ankylosis refers to the stiffening or fusion of joints. Therefore, Scoliosis is the most appropriate term to describe an abnormal lateral curvature of the spine.Rate this question:

The beta cells in the pancreas are responsible for the production of
- A.
Glucagon
- B.
HCI
- C.
Insulin
- D.
Gastrin
- E.
Pepsin
Correct Answer
C. InsulinExplanation
The beta cells in the pancreas are responsible for the production of insulin.
