Examples of a ball and socket joint is
- A. Interphalangeal joint
- B. Knee joint
- C. Shoulder joint
- D. Elbow joint
Correct Answer: C
Rationale: The correct answer is C: Shoulder joint. A ball and socket joint allows for multi-directional movement with a wide range of motion. The shoulder joint fits this description as it consists of the ball-shaped head of the humerus bone fitting into the socket of the scapula bone. This anatomical structure allows for movements like flexion, extension, abduction, adduction, and rotation. In contrast, the interphalangeal joint (A) is a hinge joint, the knee joint (B) is a hinge joint, and the elbow joint (D) is a pivot joint, none of which have the same range of motion as a ball and socket joint.
Which hormone stimulates the secondary female sex organs?
- A. FSH
- B. LH
- C. GnRH
- D. estrogen
Correct Answer: D
Rationale: The correct answer is D: estrogen. Estrogen is the hormone that stimulates the growth and development of secondary female sex organs like the breasts, uterus, and fallopian tubes. It plays a crucial role in regulating the menstrual cycle and preparing the body for pregnancy. FSH and LH are hormones released by the pituitary gland that primarily regulate the ovarian cycle, while GnRH is a hormone released by the hypothalamus to stimulate the pituitary gland to release FSH and LH. Estrogen, being a primary female sex hormone, directly influences the development and function of secondary sex organs in females.

Which of the following is produced by the trophoblast cells during the first 3 weeks of pregnancy?
- A. Estrogen
- B. Luteinizing hormone
- C. Oxytocin
- D. Human chorionic gonadotropin
Correct Answer: D
Rationale: The correct answer is D: Human chorionic gonadotropin (hCG). During the first 3 weeks of pregnancy, trophoblast cells produce hCG, which is crucial for maintaining the corpus luteum and ensuring the production of progesterone to support the early pregnancy. hCG is also the hormone detected in pregnancy tests.
Rationale:
A: Estrogen is mainly produced by the ovaries, not trophoblast cells in the early stages of pregnancy.
B: Luteinizing hormone is produced by the pituitary gland to trigger ovulation, not by trophoblast cells.
C: Oxytocin is produced by the hypothalamus and released by the pituitary gland during labor and breastfeeding, not by trophoblast cells in the early stages of pregnancy.

B: Ovary is incorrect as ovaries are reproductive organs in females that produce eggs, not milk.
C: Cervix is incorrect as it is a part of the female reproductive system that connects the vagina to the uterus, not involved in milk production.
D: Zygote is incorrect as it is the initial cell formed from the fusion of sperm and egg during fertilization, not related to milk production.
