Practice Science TEAS Test

Correct Answer: B

Rationale: The correct answer is B: Pancreas. The pancreas produces digestive enzymes such as amylase, lipase, and proteases that help break down carbohydrates, fats, and proteins in the small intestine. The liver (A) produces bile but not digestive enzymes. The gallbladder (C) stores bile produced by the liver. The esophagus (D) is responsible for transporting food from the mouth to the stomach, not for producing digestive enzymes.

Correct Answer: B

Rationale: The correct answer is B: Fibrous joint. Fibrous joints are immovable joints that connect bones with dense fibrous connective tissue. In the skull, the bones are joined by fibrous sutures, which provide stability and protect the brain. Hinge joints (A) allow movement in one direction, not present in the skull. Ball-and-socket joints (C) allow for a wide range of motion, not fitting the immovable nature of skull joints. Pivot joints (D) allow rotation, which is not a characteristic of skull joints. Therefore, the fibrous joint is the correct type of joint that connects the bones of the skull.

Correct Answer: A

Rationale: The correct answer is A: Ribosome. Ribosomes are responsible for protein synthesis as they are the site where amino acids are assembled into proteins. They can be found in both the cytoplasm and attached to the endoplasmic reticulum. The other choices are incorrect because the nucleus houses the cell's genetic material, the mitochondrion is responsible for energy production, and the Golgi apparatus is involved in protein processing and packaging, not protein synthesis.

Correct Answer: B

Rationale: The correct answer is B: Luteinizing Hormone. The pituitary gland secretes luteinizing hormone, which plays a crucial role in the reproductive system by stimulating ovulation in females and testosterone production in males. Estrogen, progesterone, and testosterone are not directly released by the pituitary gland but are instead produced by other glands such as the ovaries, testes, and adrenal glands. Therefore, B is the correct choice as it is the hormone directly released by the pituitary gland.

Correct Answer: D

Rationale: The correct answer is D because anatomical terms use specific directions to describe relationships between body parts. In this case, "lateral" refers to the side of the body, so the thumb being on the lateral aspect of the hand is accurate. The other choices are incorrect because they do not follow anatomical terminology standards. Choice A incorrectly compares the shoulder joint to the neck using proximity, not specific directional terms. Choice B uses "superior" incorrectly to describe the elbow joint in relation to the shoulder. Choice C inaccurately compares the thoracic and cervical vertebrae using the term "superior," which is not anatomically correct in this context.
