Introduction to Anatomy and Physiology Lesson 1.1 Study Questions Questions
Question 1 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 2 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.
Question 3 of 5
Which part of the body begins the breakdown of foods and makes digestive juice that can kill most bacteria?
Correct Answer: D
Rationale: The stomach, initiates food breakdown via mechanical churning and secretes gastric juice (acid, enzymes) that kills bacteria. The liver produces bile, heart pumps blood, colon absorbs water, and skin protects. Anatomically, the stomach's acidic environment (pH A.5-C.5) digests and sterilizes, aligning with digestion's start, confirming D.
Question 4 of 5
The self-correcting process that helps to maintain stability and restore a homeostatic set point is known as:
Correct Answer: A
Rationale: Negative feedback, restores homeostasis by countering deviations e.g., cooling when overheated. Stimulus triggers, sensor detects, positive feedback amplifies (e.g., childbirth), and disease disrupts. Anatomically, negative feedback (thermoregulation) stabilizes variables like temperature, making A the self-correcting mechanism.
Question 5 of 5
The directional term 'superior' in anatomy means which of the following?
Correct Answer: A
Rationale: Superior denotes a position closer to the head, aligning with the cephalic direction in anatomical terms. It's used to compare structures like the eyes being superior to the mouth offering a vertical hierarchy. In clinical practice, nurses apply this to locate issues, such as superior lung infections, ensuring precise communication. It contrasts with tailward or front-back terms, anchoring orientation in the body's upright framework for effective care and study.
