Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
What is the scientific term for the armpit?
Correct Answer: C
Rationale: Axillary refers to the armpit, not acromial (A, shoulder), brachial (B, arm), or sternal (D, chest). Anatomical terms like axillary pinpoint regions, vital for procedures like lymph node checks, confirming C.
Question 2 of 5

Correct Answer: A
Rationale: The diaphragm, a muscular sheet, separates thoracic (chest) and abdominopelvic cavities, unlike mediastinum (B, chest divider), sternum (C, breastbone), or ventral cavity (D, broader). Anatomically, it regulates breathing and cavity distinction, confirming A.
Question 3 of 5
Which of the following is NOT found in the mediastinum?
