Introduction to Anatomy and Physiology Lesson 1.1 Study Questions Questions
Question 1 of 5
The vertebral canal and cranial cavity is located within the ___ cavity.
Correct Answer: B
Rationale: The dorsal cavity includes the cranial (brain) and vertebral (spinal cord) cavities, not ventral (A, front), abdominopelvic, or cranial alone. This posterior grouping in anatomy protects the central nervous system, making B correct.
Question 2 of 5
The stomach would lie in the ___ quadrant of the abdominopelvic cavity.
Correct Answer: A
Rationale: The stomach is in the upper left quadrant, below the diaphragm, left of midline, unlike lower left, upper right, or lower right. Quadrant mapping in anatomy pinpoints organs for diagnosis, confirming A.
Question 3 of 5
Identify the system that consists of the glands that secrete hormones.
Correct Answer: D
Rationale: The endocrine system (e.g., thyroid) secretes hormones, unlike integumentary (A, skin), cardiovascular (B, circulation), or digestive (C, food). Anatomy ties glands to regulation e.g., insulin from pancreas making D correct.
Question 4 of 5
What is the mechanism called which brings about an increasing change in the same direction?
Correct Answer: B
Rationale: Positive feedback amplifies change (e.g., childbirth contractions), unlike homeostasis (A, stability), negative feedback (C, reversal), or homeothermic (D, temperature). Anatomy highlights this in rare escalating processes, confirming B.
Question 5 of 5
The sagittal plane divides the human body into:
Correct Answer: B
Rationale: The sagittal plane divides the body into left and right portions, as per the document (answer B). This vertical plane runs longitudinally, with the midsagittal plane splitting symmetrically. Unlike transverse (A, C, horizontal), coronal (D, front-back), or cavity-specific divisions, sagittal is key in anatomy for lateral symmetry analysis e.g., comparing left and right brain hemispheres. Its precision aids in imaging and surgical planning, distinguishing it from other planes.
