Introduction to Anatomy and Physiology Lesson 6.1 Study Questions Questions
Question 1 of 5
Identify the two primary cavities within the ventral cavity.
Correct Answer: B
Rationale: The ventral cavity's primary subdivisions are thoracic (chest) and abdominopelvic, not dorsal (A, D, back), cranial (C, dorsal). B aligns with anatomy's anterior cavity organization, housing vital organs like lungs and stomach.
Question 2 of 5
Identify the organ system responsible for the production of blood cells.
Correct Answer: C
Rationale: The skeletal system produces blood cells via bone marrow (hematopoiesis), unlike cardiovascular (A, circulation), muscular (B, movement), or integumentary (D, skin). Anatomy links bones to blood formation, confirming C.
Question 3 of 5
Which membrane inflammation is correctly matched with the organ involved?
Correct Answer: B
Rationale: Meningitis inflames meninges around the brain and spinal cord, unlike pericarditis (heart), pleurisy (lungs), or peritonitis (abdomen). Anatomical membrane specificity ensures accurate diagnosis, making B correct.
Question 4 of 5
A disease that occurs suddenly and usually lasts for only a short time is called:
Correct Answer: C
Rationale: Acute diseases onset rapidly and resolve quickly (e.g., flu), unlike chronic (A, prolonged), systemic (B, widespread), or local (D, limited). Anatomy and medicine use this for temporal classification, confirming C.
Question 5 of 5
Which plane divides the human body into dorsal (back) and ventral (front) or posterior and anterior planes?
Correct Answer: B
Rationale: The coronal plane, divides the body into dorsal (back) and ventral (front), or posterior and anterior sections. Sagittal splits left-right, transverse/horizontal (C, D) upper-lower, and superior isn't a plane. This frontal plane is vital in anatomy for visualizing front-back relationships e.g., sternum anterior to spine used in cross-sectional studies like MRI, confirming B.
