What is the anatomical term for the back of the body? Example: Shoulder blade.
- A. Anterior
- B. Superior
- C. Posterior
- D. Inferior
Correct Answer: C
Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

What is the basic structure of an atom?
- A. Protons, neutrons, electrons
- B. Protons, electrons, ions
- C. Neutrons, electrons, ions
- D. Protons, ions, molecules
Correct Answer: A
Rationale: The basic structure of an atom consists of protons and neutrons located in the nucleus, with electrons orbiting around the nucleus in specific energy levels or shells. Protons carry a positive charge, neutrons carry no charge, and electrons carry a negative charge. This arrangement maintains the overall neutrality of the atom, with the number of protons equaling the number of electrons. Therefore, the correct answer is 'Protons, neutrons, electrons.' Choices B, C, and D are incorrect as they do not accurately represent the fundamental components of an atom. Choice B includes 'ions,' which are charged particles, not fundamental components of an atom. Choice C includes 'ions' and lacks protons. Choice D includes 'ions' and 'molecules,' which are not part of the basic structure of an atom.
Which three parts make up the large intestine?
- A. Duodenum, ileum, jejunum
- B. Cecum, colon, rectum
- C. Ileum, jejunum, rectum
- D. Colon, cecum, ileum
Correct Answer: B
Rationale: The correct answer is B: Cecum, colon, rectum. The large intestine is composed of the cecum, colon, and rectum. These parts are responsible for water absorption and feces formation. Choices A, C, and D are incorrect. A contains parts of the small intestine (duodenum, ileum, jejunum), C has a mix of small and large intestine parts, and D includes the small intestine part ileum. Understanding the correct anatomy of the large intestine is essential for distinguishing it from the small intestine.
What are the primary differences between systemic and pulmonary circulation?
- A. Systemic circulation is shorter and has lower blood pressure
- B. Pulmonary circulation is shorter and has higher blood pressure
- C. Systemic circulation is longer and has higher blood pressure
- D. Systemic circulation is shorter but has higher blood pressure
Correct Answer: C
Rationale: The correct answer is C. Systemic circulation is longer as it involves carrying oxygenated blood throughout the body, requiring higher blood pressure. Pulmonary circulation is shorter and involves the flow of blood only through the lungs, hence having lower blood pressure. Therefore, systemic circulation is longer and has higher blood pressure compared to pulmonary circulation. Choice A is incorrect as systemic circulation is longer, not shorter, and has higher blood pressure. Choice B is incorrect as pulmonary circulation has lower blood pressure, not higher. Choice D is incorrect as systemic circulation is longer, not shorter, despite having higher blood pressure.
Which of the following functions corresponds to the parasympathetic nervous system?
- A. It stimulates the fight-or-flight response.
- B. It increases heart rate.
- C. It stimulates digestion.
- D. It increases bronchiole dilation.
Correct Answer: C
Rationale: The parasympathetic nervous system is often referred to as the 'rest and digest' system because it promotes activities that occur when the body is at rest, such as digestion. This system helps stimulate digestion by increasing gastrointestinal motility, secretion of digestive enzymes, and blood flow to the digestive organs. Choices A, B, and D are incorrect because they are functions associated with the sympathetic nervous system, which is responsible for the 'fight-or-flight' response, increasing heart rate, and dilating bronchioles to facilitate more oxygen intake during stressful situations.
Which of the following lists the structures found beneath the rib in descending order?
- A. Nerve → Artery → Vein
- B. Vein → Nerve → Artery
- C. Vein → Artery → Nerve
- D. Artery → Nerve → Vein
Correct Answer: C
Rationale: The correct order of structures found beneath the rib in descending order is Vein → Artery → Nerve. This sequence is important to remember for medical procedures like inserting a chest tube to ensure precision and avoid complications. Choice A is incorrect because the nerve is not typically the structure closest to the rib. Choice B is incorrect as the vein is usually closer to the rib than the nerve. Choice D is incorrect as the artery is usually closer to the rib than the nerve.
