Introduction to Anatomy and Physiology Lesson 6.1 Study Questions Questions
Question 1 of 5
The term that describes body parts that are on the same side of the body is:
Correct Answer: A
Rationale: Ipsilateral means same side (e.g., right arm and leg), unlike anterior (B, front), contralateral (C, opposite side), or peripheral (D, outer). This anatomical term aids in mapping unilateral relationships, critical for clinical descriptions like nerve pathways.
Question 2 of 5
The plane that divides a body part into anterior and posterior sections is the ___ plane.
Correct Answer: C
Rationale: The frontal (coronal) plane divides anterior (front) and posterior (back), not sagittal (B, left-right) or transverse (implied). A and C overlap terms, but C alone is standard. This plane's use in anatomy, like frontal brain sections, makes it correct.
Question 3 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 4 of 5
Which of the following is NOT found in the abdominopelvic cavity?
Correct Answer: A
Rationale: The abdominopelvic cavity houses stomach, liver, and bladder, but not the heart, which is thoracic. Anatomy's cavity division ensures organ placement clarity, with the heart above the diaphragm.
Question 5 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.
