Nokea
Breastbone is otherwise known as
- A. Xiphoid process
- B. Sternum
- C. Clavicle
- D. Coracoid process
Correct Answer: B
Rationale: The correct answer is B: Sternum. The sternum is commonly referred to as the breastbone because it is a flat bone located in the center of the chest. It connects to the rib cage and helps protect vital organs such as the heart and lungs. The xiphoid process (choice A) is the lower part of the sternum, the clavicle (choice C) is the collarbone, and the coracoid process (choice D) is a projection on the scapula. Therefore, the sternum is the most appropriate term for the breastbone.

Which bone is called as the shoulder bone
- A. Clavicle
- B. Sternum
- C. Humerus
- D. Scapula
Correct Answer: D
Rationale: The correct answer is D: Scapula. The scapula is commonly known as the shoulder blade and is the bone that connects the upper arm bone (humerus) to the collarbone (clavicle) to form the shoulder joint. The other choices, A: Clavicle, is the collarbone; B: Sternum, is the breastbone; and C: Humerus, is the upper arm bone, are not specifically referred to as the shoulder bone. Therefore, the scapula is the correct answer as it is directly associated with the shoulder joint.
At the level of the testicle, the efferent ducts:
- A. continue the rete testis;
- B. open in the epididymal duct;
- C. open in the deferent duct;
- D. are 30;
Correct Answer: A
Rationale: Rationale for Correct Answer A: The efferent ducts continue the rete testis. This is true because the efferent ducts are a series of small ducts that connect the rete testis to the epididymis. The rete testis is a network of tubules located at the back of the testicle where spermatozoa from the seminiferous tubules are collected. Therefore, the efferent ducts serve to transport spermatozoa from the rete testis to the epididymis for further maturation.
Summary of Incorrect Choices:
B: Opening in the epididymal duct is incorrect because the efferent ducts lead into the epididymis, not the epididymal duct itself.
C: Opening in the deferent duct is incorrect because the efferent ducts do not lead directly into the deferent duct, but rather connect the rete testis to the epididym
A 49-yr-old man who has type 2 diabetes, high blood pressure, hyperlipidemia, and gastroesophageal reflux tells the nurse that he has had recent difficulty in achieving an erection. Which of the following drugs from his current medications list may cause erectile dysfunction (ED)?
- A. Ranitidine (Zantac)
- B. Atorvastatin (Lipitor)
- C. Propranolol (Inderal)
- D. Metformin (Glucophage)
Correct Answer: C
Rationale: The correct answer is C: Propranolol (Inderal). Propranolol is a beta-blocker commonly used to treat high blood pressure, which can lead to erectile dysfunction (ED) as a side effect by affecting blood flow. The other choices, A: Ranitidine (Zantac) is an H2 blocker used for GERD; B: Atorvastatin (Lipitor) is a statin used to lower cholesterol; and D: Metformin (Glucophage) is an oral antidiabetic agent. These medications are not typically associated with causing ED.
Hair like process on the sperm cell that makes it motile or moveable is
- A. Cilia
- B. Flagella
- C. Pseudopodia
- D. Dendritic processes
Correct Answer: B
Rationale: The correct answer is B: Flagella. Flagella are whip-like structures that provide motility to sperm cells. They enable the sperm cell to move towards the egg for fertilization. Cilia (choice A) are shorter hair-like structures involved in movement but are not found on sperm cells. Pseudopodia (choice C) are temporary projections used for cell movement in some organisms, not sperm cells. Dendritic processes (choice D) refer to branching extensions of nerve cells, not involved in sperm motility. Therefore, flagella is the most appropriate choice for the hair-like process on the sperm cell that makes it motile.

- A. Valsalva maneuver
- B. Kegel maneuver
