This ATI TEAS Practice Test A on is a highly popular, 18 -question set specifically designed to
help nursing students master core science concepts for the Test of Essential Academic Skills
(TEAS).
Below is the verified breakdown of the core exam questions, answers, and scientific explanations
featured in this specific study set.
Key Science Concepts and Explanations
• Integumentary System: Keratinocytes form a waterproof barrier in the skin.
• Physiology: Fear triggers the liver to release glucose into the blood.
• Renal System: Kidneys function to filter salts, waste, and excess water from the blood.
• Cellular Structure: Lysosomes are responsible for recycling waste materials via enzymes.
• Musculoskeletal System: Ligaments connect bone to bone.
• Digestive System: Villi and microvilli increase surface area for nutrient absorption.
• Immune System: B-cells are responsible for producing antibodies.
• Endocrine System: Type I diabetes is caused by a lack of insulin

, ANSWER✅
Which of the following connects two bones together?
A. Ligament
B. Tendon
C. Marrow
D. Muscle
Quiz_________________?
B. 46 chromosomes
The fusion of a sperm with 23 chromosomes and an egg with 23 chromosomes would result
in a zygote with 46 chromosomes. -
ANSWER✅
Which of the following options represents the chromosomal composition of a normal
human zygote?
A. 23 chromosomes
B. 46 chromosomes
C. 69 chromosomes
D. 96 chromosomes
Quiz_________________?
B. Disrupted propagation of an action potential along the axon of a nerve.
The myelin sheath, which is a lipid-based structure, insulates the axon, allowing rapid
electrical conduction of the action potential down the axon. Deterioration of the myelin
sheath disrupts this process. -
