ATI TEAS Science Practice Test Questions
Question 1 of 5
What are the structural and functional units responsible for creating and transporting urine, located in the cortex of the kidney?
Correct Answer: B
Rationale: The correct answer is 'Nephrons.' Nephrons are the structural and functional units of the kidneys responsible for creating and transporting urine. Each kidney contains thousands of nephrons located in the cortex and medulla. The nephron consists of the renal corpuscle, which includes the glomerulus, and the renal tubule, which consists of the proximal tubule, loops of Henle, and distal tubule. While the glomerulus, loops of Henle, and distal tubules are all parts of the nephron, the nephrons as a whole are specifically responsible for creating and transporting urine.
Question 2 of 5
What is the anatomical term for the back of the body? Example: Shoulder blade.
Correct Answer: C
Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.
Question 3 of 5
Which term refers to a position toward the feet? For example, the foot is part of the inferior extremity.
Correct Answer: D
Rationale: The correct answer is 'Inferior.' 'Inferior' refers to a position located towards the feet or lower part of the body. This is the opposite of 'superior,' which indicates a position towards the head or upper part of the body. 'Anterior' refers to the front of the body, 'posterior' refers to the back of the body, making them incorrect choices in this context.
Question 4 of 5
Which term refers to a position farther from the midline of the body? For example, the little toe is lateral to the big toe on the same foot.
Correct Answer: A
Rationale: The correct answer is A: Lateral. Lateral refers to a position farther away from the midline of the body. In the example provided, the little toe is indeed lateral to the big toe on the same foot. This is in contrast to 'medial,' which means closer to the midline. 'Proximal' refers to a position closer to the point of attachment or the trunk of the body, while 'distal' refers to a position farther from the point of attachment or the trunk of the body.
Question 5 of 5
Which plane divides the body into left and right halves?
Correct Answer: A
Rationale: The correct answer is A: Sagittal/Median Plane. This plane divides the body into left and right halves. The Frontal/Coronal Plane (choice B) divides the body into front and back, while the Transverse/Cross-Section Plane (choice C) divides it into top and bottom. The Horizontal Plane (choice D) divides the body into upper and lower portions. Understanding these planes is essential in anatomy as they help describe the orientation and relationships of body structures.
