TEAS 7 science practice questions
1. The framework of bones, cartilage, ligaments, and tendons that provides structure, support, and facilitates movement is part of the:
- A. Muscular system
- B. Skeletal system
- C. Nervous system
- D. Endocrine system
Correct answer: B
Rationale: The skeletal system consists of bones, cartilage, ligaments, and tendons that work together to provide structure, support, protection for internal organs, and facilitate movement. It is responsible for supporting the body's framework and protecting vital organs. The muscular system (option A) consists of muscles that work with the skeletal system to produce movement but does not include bones, cartilage, ligaments, and tendons. The nervous system (option C) is responsible for transmitting signals throughout the body to control movement and other functions. The endocrine system (option D) is a collection of glands that produce hormones to regulate various bodily functions but is not primarily involved in structure, support, and movement as the skeletal system is.
2. What type of muscle is found in the walls of hollow organs like the intestines?
- A. Cardiac muscle
- B. Smooth muscle
- C. Skeletal muscle
- D. Voluntary muscle
Correct answer: B
Rationale: Smooth muscle is the correct type of muscle found in the walls of hollow organs like the intestines. It is responsible for movements such as peristalsis, aiding in the movement of food and other materials through the digestive system. Cardiac muscle (Choice A) is found in the heart and is responsible for the heart's contractions, not in hollow organs like the intestines. Skeletal muscle (Choice C) is attached to bones and responsible for voluntary movements, not in hollow organ walls. Voluntary muscle (Choice D) is another term for skeletal muscle, which is under conscious control, unlike smooth muscle in hollow organ walls.
3. Which of the following nutrients is essential for muscle growth and repair?
- A. Vitamin C
- B. Protein
- C. Carbohydrates
- D. Fat
Correct answer: B
Rationale: Protein is essential for muscle growth and repair as it provides the necessary building blocks (amino acids) for muscle tissue synthesis and repair. While vitamins and minerals are crucial for overall health, protein has a specific role in muscle development. Carbohydrates supply energy for workouts, and fats are important for general health but are less directly involved in muscle growth and repair compared to protein.
4. Which vitamin deficiency can lead to kidney stones?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin D
- D. Vitamin K
Correct answer: C
Rationale: The correct answer is Vitamin D. Vitamin D deficiency can lead to kidney stones because Vitamin D helps regulate calcium levels in the body. Low levels of Vitamin D can result in increased calcium absorption from the intestines, leading to higher levels of calcium in the urine, which can form kidney stones. Choices A, B, and D are incorrect as deficiencies in these vitamins are not directly associated with kidney stone formation.
5. Which type of muscle tissue contracts involuntarily and is found in organs like the heart and intestines?
- A. Skeletal muscle
- B. Cardiac muscle
- C. Smooth muscle
- D. All of the above
Correct answer: C
Rationale: Smooth muscle is the type of muscle tissue that contracts involuntarily and is found in organs like the heart and intestines. Skeletal muscle is responsible for voluntary movements, like those involved in skeletal system actions. Cardiac muscle is found in the heart and contracts involuntarily, but it is distinct from smooth muscle. The heart's muscle is specialized and forms the myocardium, which is not the same as the smooth muscle found in organs like the intestines. Therefore, the correct answer is C) Smooth muscle.
