Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
Which of the following is/are the contents of the dorsal body cavity?
Correct Answer: B
Rationale: The dorsal cavity, along the body's back, encases the brain and spinal cord, safeguarding the central nervous system. Unlike ventral organs, these structures govern thought and coordination. Nurses focus here for neurological issues like spinal injuries distinct from thoracic or abdominal contents. This cavity's protective role is key, housing the body's command center for effective health management.
Question 2 of 5
Which of the following best describes the 'anatomical position'?
Correct Answer: D
Rationale: The anatomical position stands upright, arms at sides, palms up, presenting the ventral surface forward. Nurses adopt this as a universal reference like for chest exams unlike spread or clasped stances. It aligns directional terms, ensuring consistent anatomical communication across medical practice.
Question 3 of 5
Which of the following is not true?
Correct Answer: A
Rationale: Pathology examines disease, not life's essence, which aligns with biology's broader scope. Organ function indeed ties to structure like the heart's chambers pumping blood and homeostasis is vital for stability. However, negative feedback dominates, correcting deviations like temperature spikes, while positive feedback, amplifying events like childbirth, is rarer. Nurses rely on this understanding to manage conditions, recognizing stability mechanisms outweigh escalatory ones in daily physiology.
Question 4 of 5
A person in a prone position would be:
Correct Answer: A
Rationale: Prone position means lying face down, unlike anatomical position (B, standing, palms forward), erect (C, upright), or fetal (D, curled). Anatomically, prone contrasts with supine (face up), used in procedures like back surgery, aligning body orientation with functional context, confirming A.
Question 5 of 5
The abdominal cavity contains the:
Correct Answer: C
Rationale: The abdominal cavity holds the spleen, below the diaphragm, unlike heart and lungs (B, thoracic), or trachea (D, thoracic/neck). Anatomically, it spans diaphragm to pelvis, housing digestive organs (e.g., spleen filters blood), making C correct.
