TEAS version 7 quizlet science

1. What is the outermost protective layer of the kidney?

Correct answer: C

Rationale: The correct answer is C, Renal capsule. The renal capsule is the outermost protective layer of the kidney. It is a tough fibrous layer that surrounds the kidney and helps protect it from injury and maintain its shape. Choice A, Renal cortex, is the outer region of the kidney where filtration occurs. Choice B, Renal medulla, is the inner region of the kidney where urine is formed. Choice D, Renal pelvis, is the funnel-shaped structure that collects urine from the kidney and funnels it into the ureter. Therefore, the renal capsule is specifically designated as the outermost protective layer of the kidney.

2. Which of the following best describes the function of the pericardium?

Correct answer: B

Rationale: The pericardium is a double-layered sac that surrounds and protects the heart. Its main functions include preventing overfilling of the heart, providing a physical barrier against infection and inflammation, and reducing friction between the heart and surrounding structures. Choices A, C, and D do not accurately describe the function of the pericardium. Option B is the correct answer as it aligns with the protective and supportive role of the pericardium, distinguishing it from the functions attributed to choices A, C, and D.

3. What is the function of fascia in muscle tissue?

Correct answer: A

Rationale: The correct answer is A: 'to enclose, protect, support, and separate muscle tissue.' Fascia is a connective tissue that surrounds muscles, providing structural support, protecting them from friction and injury, and helping in movement. Choice B is incorrect as tendons are responsible for connecting muscle tissue to bone. Choice C is incorrect as the contractile unit of muscle is the sarcomere, not fascia. Choice D is incorrect as the process described relates to muscle contraction mechanisms involving actin and myosin, not the function of fascia.

4. What is the scientific name for the kneecap?

Correct answer: A

Rationale: The correct answer is A: Patella. The patella is the scientific term for the kneecap, a small, flat, triangular bone situated in front of the knee joint. The femur, tibia, and fibula are also bones in the leg, but they are not synonymous with the kneecap. The femur is the thigh bone, the tibia is the shin bone, and the fibula is the outer lower leg bone. Therefore, the correct term for the kneecap specifically is the patella.

5. Which of the following is an example of Mendelian inheritance?

Correct answer: D

Rationale: The correct answer is D, 'Recessive Inheritance.' Mendelian inheritance involves traits controlled by single genes with dominant and recessive alleles. Incomplete dominance (choice A) is a non-Mendelian inheritance pattern where the heterozygous phenotype is a blend of the two homozygous phenotypes. Polygenic alleles (choice B) involve multiple genes contributing to a single trait, not following Mendelian principles. Combination inheritance (choice C) is not a recognized term in genetics and does not describe Mendelian inheritance patterns.
