Practice Science TEAS Test Questions

Question 1 of 5

Which of the following nerves has the longest axon in the human body?

Correct Answer: C

Rationale: The correct answer is C: Sciatic nerve. The sciatic nerve is the longest and thickest nerve in the human body, running from the lower back down the back of each leg. Its length allows it to innervate a large portion of the lower body. The other choices, A: Dorsal root ganglion and B: Laryngeal nerve, are not nerves but rather specific structures within the nervous system. Choice D: None of the above is incorrect as the sciatic nerve is indeed the nerve with the longest axon in the human body.

Question 2 of 5

Which of the following is another name for a sweat gland?

Correct Answer: C

Rationale: The correct answer is C: Sudoriferous. Sudoriferous glands are commonly known as sweat glands. These glands are responsible for producing sweat, which helps regulate body temperature. "Ceruminous" glands produce earwax, "Sebaceous" glands produce oil, and "Integumentary" refers to the skin as a whole, not specifically to sweat glands. Therefore, the correct choice is C.

Question 3 of 5

What is the end product of glycolysis?

Correct Answer: D

Rationale: The correct answer is D: Pyruvic acid. In glycolysis, glucose is broken down into pyruvic acid. This process generates ATP and NADH as well. Lactic acid (A) is produced in anaerobic conditions, not at the end of glycolysis. ATP (B) is produced during glycolysis but is not the end product. NADPH (C) is not the end product of glycolysis, it is produced in the pentose phosphate pathway.

Question 4 of 5

Which of the following lobes of the brain is responsible for sensation, perception, and spatial reasoning?

Correct Answer: C

Rationale: The correct answer is C: Parietal lobe. The parietal lobe is responsible for processing sensory information, perception of stimuli, and spatial reasoning. It integrates information from different senses to create a coherent understanding of the world around us. The frontal lobe (A) is mainly involved in executive functions and motor control. The occipital lobe (B) is primarily responsible for processing visual information. The temporal lobe (D) is associated with auditory perception, memory, and language processing. Therefore, the parietal lobe is the most suitable choice for sensation, perception, and spatial reasoning.

Question 5 of 5

Which organ is responsible for filtering waste from the blood?

Correct Answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are responsible for filtering waste products, excess fluids, and toxins from the blood to form urine. Step-by-step rationale: 1. The kidneys contain millions of tiny filtering units called nephrons. 2. Blood flows through the nephrons, where waste products are removed and urine is formed. 3. The urine then flows through the ureters to the bladder for storage and eventual elimination. Other choices are incorrect because: B: Pancreas - produces digestive enzymes and regulates blood sugar, not primarily involved in waste filtration. C: Liver - detoxifies chemicals, produces bile, and stores nutrients, but not the primary organ for blood filtration. D: Heart - pumps blood and circulates it throughout the body, not directly involved in waste filtration.
