The topographical term used to describe the location of the body parts that are closer to the median plane is:
- A.
Lateral
- B.
Medial
- C.
Midaxillary
- D.
Midclavicular
Correct Answer
B. MedialExplanation
The term "medial" is used to describe body parts that are closer to the median plane. The median plane is an imaginary vertical plane that divides the body into left and right halves. Therefore, "medial" refers to body parts that are closer to the midline of the body, while "lateral" refers to body parts that are farther away from the midline. "Midaxillary" and "midclavicular" are not topographical terms used to describe the location of body parts in relation to the median plane.Rate this question:

A patient was struck in the right lower anterior chest with a baseball bat. In addition to fractured ribs, you should be suspicious of injury to the:
- A.
Spleen
- B.
Liver
- C.
Pancreas
- D.
Stomach
Correct Answer
B. LiverExplanation
When a patient is struck in the right lower anterior chest with a baseball bat, there is a high likelihood of injury to the liver. This is because the liver is located in the right upper quadrant of the abdomen, just below the right lower anterior chest. The forceful impact of the baseball bat can cause the liver to be compressed against the rib cage, leading to injury such as liver laceration or rupture. Therefore, in addition to fractured ribs, suspicion of liver injury should be high in such cases.Rate this question:

A patient is found to have a high blood sugar level (hyperglycemia). What is the cause of this?
- A.
Excessive insulin levels in the blood
- B.
Decreased production of glucagon
- C.
Deficient insulin levels in the blood
- D.
Hyperactivity of the pancreatic beta cells
Correct Answer
C. Deficient insulin levels in the bloodExplanation
The correct answer is deficient insulin levels in the blood. Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. When there is a deficiency of insulin, glucose cannot be effectively transported into cells, leading to high blood sugar levels. This condition is known as hyperglycemia. Excessive insulin levels in the blood would actually result in low blood sugar levels, not high. Decreased production of glucagon and hyperactivity of the pancreatic beta cells do not directly cause high blood sugar levels.Rate this question:

The two major veins that drain the head and neck of blood are the _______ veins.
- A.
Vertebral
- B.
Jugular
- C.
Cerebral
- D.
Cephalic
Correct Answer
B. JugularExplanation
The jugular veins are the two major veins that drain the head and neck of blood. They are responsible for carrying deoxygenated blood from the brain, face, and neck back to the heart. The vertebral veins, on the other hand, drain the spinal cord and do not play a major role in draining the head and neck. The cerebral veins are responsible for draining blood from the brain itself. The cephalic vein is located in the arm and is not involved in draining the head and neck.Rate this question:

Normal inspiration is the result of:
- A.
Diaphragmatic relaxation.
- B.
Air passively entering the lungs.
- C.
Negative pressure in the the thoracic cavity
- D.
Positive pressure in the thoracic cavity
Correct Answer
C. Negative pressure in the the thoracic cavityExplanation
Normal inspiration is the result of negative pressure in the thoracic cavity. When the diaphragm relaxes and the intercostal muscles contract, the volume of the thoracic cavity increases. This leads to a decrease in pressure within the thoracic cavity, causing air to passively enter the lungs to equalize the pressure. Therefore, normal inspiration occurs due to the negative pressure created in the thoracic cavity.Rate this question:

A fracture of the orbital bone is commonly referred to as a _________ fracture.
- A.
Blowout
- B.
Midface
- C.
Lefort
- D.
Basilar
Correct Answer
A. BlowoutExplanation
A fracture of the orbital bone is commonly referred to as a blowout fracture. This type of fracture occurs when there is a forceful impact to the eye socket, causing the bone to break. The term "blowout" is used because the fracture often results in a portion of the orbital bone being pushed or "blown out" into the surrounding sinuses. This can lead to symptoms such as double vision, pain, swelling, and difficulty moving the eye. Treatment typically involves surgery to repair the fractured bone and restore normal function.Rate this question:

The semilunar valves of the heart fundtion by:
- A.
Preventing backflow of blood into the atria.
- B.
Minimizing the forward flow of blood.
- C.
Attaching to the papillary muscles.
- D.
Preventing backflow of blood into the ventricles.
Correct Answer
D. Preventing backflow of blood into the ventricles.Explanation
The semilunar valves of the heart prevent backflow of blood into the ventricles. These valves are located at the base of the pulmonary artery and aorta, and they open and close to allow blood to flow out of the ventricles and into the arteries. When the ventricles contract, the semilunar valves open, allowing blood to be pumped out. When the ventricles relax, the valves close, preventing blood from flowing back into the ventricles and ensuring that it only moves forward into the arteries.Rate this question:

Closure of the tricuspid and mitral valves occur during:
- A.
Ventricular relaxation
- B.
Ventricular contraction
- C.
The diastolic phase
- D.
Atrial contraction
Correct Answer
B. Ventricular contractionExplanation
During ventricular contraction, the tricuspid and mitral valves close. This is because the contraction of the ventricles causes an increase in pressure, forcing the blood to be pushed out of the ventricles and into the arteries. To prevent backflow of blood into the atria during this process, the tricuspid and mitral valves close, ensuring that the blood flows in the correct direction. Therefore, ventricular contraction is the phase in which closure of these valves occurs.Rate this question:

What is the function of a baroreceptor?
- A.
Monitoring changes in arterial pressure.
- B.
Sensing changes in arterial oxygen levels
- C.
Monitoring the pH of cerebrospinal fluid
- D.
Sensing the arterial level of carbon dioxide
Correct Answer
A. Monitoring changes in arterial pressure.Explanation
Baroreceptors are specialized sensory receptors that monitor changes in arterial pressure. They are located in the walls of certain blood vessels, such as the carotid sinus and aortic arch. When there is a change in blood pressure, these receptors send signals to the brain, which then initiates appropriate responses to regulate blood pressure and maintain homeostasis. This function helps to ensure that blood pressure remains within a normal range and prevents any sudden or drastic changes that could be harmful to the body.Rate this question:
