The process in which sperm are hormone (FSH) have on males? streamlined into a head, midpiece,

  • A. Male testes are not and tail is called ________.
  • B. spermatogenesis
  • C. FSH functions solely in
  • D. acrosomal reaction
Correct Answer: B

Rationale: The correct answer is B: spermatogenesis. Spermatogenesis is the process by which sperm cells are produced in the male testes. FSH (follicle-stimulating hormone) plays a crucial role in stimulating the production of sperm within the testes. During spermatogenesis, sperm cells go through various stages of development, including the formation of a head, midpiece, and tail. The other choices are incorrect because:
A: Male testes are not and tail is called ________. This statement is incomplete and does not make sense in the context of the question.
C: FSH functions solely in. This choice is incomplete and does not provide any relevant information about the process of sperm production.
D: Acrosomal reaction. This term refers to a specific event that occurs during fertilization and is not directly related to the overall process of sperm production in the testes.

Where does fertilization normally occur?

  • A. uterus
  • B. uterine tube
  • C. ovary
  • D. pelvic cavity
Correct Answer: B

Rationale: The correct answer is B, the uterine tube. Fertilization typically occurs in the uterine tube, also known as the fallopian tube, where the egg and sperm meet and fuse to form a zygote. This is the site where the fertilized egg begins its journey towards the uterus for implantation. The other choices are incorrect because fertilization does not occur in the uterus (A), ovary (C), or pelvic cavity (D). The uterus is where the fertilized egg implants and develops into a fetus, the ovary is where the egg is released during ovulation, and the pelvic cavity is a space that houses reproductive organs but not the site of fertilization.

Human chorionic gonadotropin (hCG) produces fluid that activates sperm.

  • A. prostatic urethra
  • B. ovary.
  • C. prostate
  • D. corpus luteum.
Correct Answer: D

Rationale: The correct answer is D: corpus luteum. Human chorionic gonadotropin (hCG) is produced by the developing placenta during pregnancy. This hormone helps maintain the corpus luteum, which in turn produces progesterone to support the pregnancy. The fluid produced by the corpus luteum helps activate sperm for fertilization. Choices A, B, and C are incorrect as they are not directly involved in the production of hCG or the activation of sperm.

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.

A hollow cavity within a bone is termed as:

  • A. Sulcus
  • B. Fossa
  • C. Fissure
  • D. Sinus
Correct Answer: B

Rationale: The correct answer is B: Fossa. A fossa is a hollow cavity or depression within a bone. It serves as an attachment site for muscles, ligaments, or tendons. Sulcus (A) is a groove or furrow, not a hollow cavity in a bone. Fissure (C) is a narrow opening or cleft, not a hollow cavity. Sinus (D) is a cavity within a bone filled with air, not necessarily hollow. Therefore, the best choice for a hollow cavity within a bone is a fossa.

Giving prostaglandin E2 (PGE2) to a pregnant woman may result in an abortion. What is the best explanation for this finding?

  • A. PGE2 strongly stimulates uterine contraction
  • B. PGE2 causes constriction of the arteries leading to the placenta
  • C. PGE2 stimulates the release of oxytocin from the posterior pituitary
  • D. PGE2 increases the secretion of progesterone from the corpus luteum
Correct Answer: A

Rationale: The correct answer is A because prostaglandin E2 (PGE2) is known to strongly stimulate uterine contractions. This can lead to abortion by triggering premature labor and causing the expulsion of the fetus. Choice B is incorrect as PGE2 does not cause arterial constriction leading to the placenta. Choice C is incorrect because PGE2 does not stimulate the release of oxytocin; rather, oxytocin itself is a hormone that stimulates uterine contractions. Choice D is also incorrect as PGE2 does not increase progesterone secretion from the corpus luteum; in fact, PGE2 can have the opposite effect by inhibiting progesterone synthesis.
