Introduction to Anatomy and Physiology Lesson 2.1 Study Questions Questions
Question 1 of 5
The lungs are situated within which body cavity?
Correct Answer: B
Rationale: The lungs reside in the thoracic cavity, within the chest, enclosed by the ribcage and diaphragm. The cranial cavity houses the brain, abdominal the stomach, pelvic the bladder, and spinal the spinal cord. Anatomically, the thoracic cavity's pleural subdivisions protect and support lung function breathing making B the correct choice, aligning with respiratory anatomy.
Question 2 of 5
Which hormone helps to maintain glucose homeostasis by stimulating liver cells to take up and remove additional glucose?
Correct Answer: A
Rationale: Insulin, lowers blood glucose by prompting liver uptake and storage as glycogen. Glucagon raises glucose, pancreas is an organ, response and starch are irrelevant. Anatomically, insulin's role in glucose homeostasis post-meal regulation prevents hyperglycemia, confirming A.
Question 3 of 5
Which of the following is the best definition of physiology?
Correct Answer: B
Rationale: Physiology explores the body's operational mechanisms how systems like circulation or respiration function in health. It's a dynamic science, revealing processes that sustain life, from nerve impulses to digestion. Nurses rely on this knowledge to support normal function like monitoring breathing rates distinguishing it from structural or cellular focuses. This broad inquiry into how' underpins medical interventions, ensuring treatments align with the body's natural workings for optimal outcomes.
Question 4 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 5 of 5
Complete the sentence correctly: 'Cervical vertebrae are......
Correct Answer: A
Rationale: Cervical vertebrae, in the neck, sit above the rib cage, a superior position in anatomical terms. Nurses assess them for neck issues like whiplash relative to the thoracic cage below. Other options fail: they're above thoracic vertebrae, precede sacral ones, and aren't fused. This placement shapes spinal care and orientation.
