Question 1 of 5
The only movable facial bone is _____________.
Correct Answer: A
Rationale: The correct answer is A: Mandible. The mandible is the only movable facial bone as it forms the lower jaw and is connected to the skull by the temporomandibular joint, allowing for movements like chewing and speaking. Maxilla, Vomer, and Ethmoid are all facial bones, but they are fixed in place and do not have the same range of motion as the mandible. Maxilla forms the upper jaw, Vomer is a bone in the nasal cavity, and Ethmoid is a bone between the eyes. Therefore, the mandible is the only bone among the options that is capable of movement, making it the correct answer.
Question 2 of 5
Which spermatid phase (spermiogenesis) is distinguished by the presence of PAS positive granules called pro acrosomal granules?
Correct Answer: A
Rationale: The correct answer is A: Golgi phase. During the Golgi phase of spermiogenesis, the proacrosomal granules are formed from the Golgi apparatus and are PAS positive. These granules will later contribute to the formation of the acrosome in mature sperm. The other choices are incorrect because: B: Cap phase - This phase is characterized by the formation of the acrosomal cap over the nucleus, not the proacrosomal granules. C: Acrosome phase - This phase involves the elongation and shaping of the acrosome, not the formation of proacrosomal granules. D: Maturation phase - This phase focuses on the final maturation and condensation of the sperm cell, not the formation of proacrosomal granules.
Question 3 of 5
Frank is a 24 year old man who presents with multiple vesicles and burning erosions on the shaft of his penis and some tender inguinal adenopathy. Which of the following is most likely?
Correct Answer: B
Rationale: The correct answer is B: Herpes simplex. This is because the presentation of multiple vesicles, burning erosions on the penis shaft, and inguinal adenopathy is classic for genital herpes. Primary syphilis (A) presents with a painless chancre, chancroid (C) with painful ulcers, and gonorrhea (D) with urethral discharge or dysuria. Genital herpes is a viral infection caused by HSV-1 or HSV-2 and typically presents with vesicles, erosions, and adenopathy in the affected area.
Question 4 of 5
The structure between the uterus and the vagina is the
Correct Answer: B
Rationale: The correct answer is B: cervix. The cervix is the structure between the uterus and the vagina, serving as the lower part of the uterus that connects to the vagina. It plays a crucial role in pregnancy by allowing sperm to enter the uterus and facilitating the passage of menstrual blood. Rationale: 1. The uterine tube (A) is not the correct answer as it connects the ovaries to the uterus and is not located between the uterus and the vagina. 2. The vulva (C) is the external genitalia and is not the structure between the uterus and the vagina. 3. The hymen (D) is a thin membrane at the opening of the vagina and does not serve as the structure between the uterus and the vagina.
Question 5 of 5
In the circulatory system of a fetus, which of the following is greater before birth than after birth?
Correct Answer: B
Rationale: The correct answer is B: Right atrial pressure. Before birth, the fetal circulatory system has a shunt called the foramen ovale that allows blood to bypass the lungs, resulting in higher pressure in the right atrium. After birth, when the foramen ovale closes, the right atrial pressure decreases. Incorrect Choices: A: Arterial Po2 - Typically, arterial Po2 is lower in the fetus due to the placenta's oxygenation, but it increases after birth. C: Aortic pressure - Aortic pressure remains relatively stable before and after birth. D: Left ventricular pressure - Left ventricular pressure increases after birth due to the transition from fetal to neonatal circulation.
