Sample questions from Anthony Textbook of Anatomy Edition 22 & Physiology Patton Bell Thompson Williamson Create ATI Style Quiz Chapter 1-7

This material has 90 questions with answers and rationales. Here are the first 5.

1. 1.During a winter walk, a person's body temperature begins to fall below its set point. Which response best illustrates negative feedback?

   • A.Skeletal muscles shiver, generating heat that helps return body temperature toward its set point.
   • B.The control center detects the temperature change but does not activate an effector.
   • C.The temperature deviation triggers responses that increase the deviation from the set point.
   • D.Sweating increases, causing additional heat loss until body temperature falls further.

   Rationale: Shivering generates heat and counteracts the initial drop in temperature, which is the defining pattern of negative feedback. Sweating would promote heat loss and worsen the cooling, while a control center that fails to activate an effector would not restore the variable. A response that amplifies the deviation describes positive rather than negative feedback.

2. 2.A histology student identifies cardiac muscle cells in a tissue sample from the heart wall. Which sequence correctly places this finding within the levels of structural organization, from simplest to most complex?

   • A.Organ, tissue, cell, organism, organ system
   • B.Cell, tissue, organ, organ system, organism
   • C.Tissue, cell, organ, organism, organ system
   • D.Cell, organ, tissue, organ system, organism

   Rationale: Cardiac muscle cells are organized into cardiac muscle tissue, which contributes to the heart as an organ, the cardiovascular system, and ultimately the organism. Tissue cannot precede the cells that compose it, so the second sequence reverses the first two levels. The third and fourth sequences also place organs or tissues out of order.

3. 3.While describing a small abrasion, a student says it is on the patient's left forearm, but the student is facing the patient and pointing to the student's own left. Which correction should the instructor make?

   • A.Call it the patient's right because the patient faces the observer.
   • B.Avoid left and right and describe the forearm as proximal to the hand.
   • C.Use the patient's left as determined with the patient in anatomical position.
   • D.Use the observer's left because directional terms are based on the person examining the patient.

   Rationale: Anatomical directional terms are based on the body in anatomical position and refer to the subject's right and left, not the observer's. The observer's left may correspond to the patient's right when they face one another, making the first and third choices incorrect. Proximal describes relative distance from a point of attachment and does not identify which forearm is involved.

4. 4.During a study-group review, learners discuss the components and patterns of homeostatic control. Which statements are accurate? Select all that apply.

   • A.In positive feedback, the response amplifies the initial change until a specific event ends the cycle.
   • B.In negative feedback, the response tends to reduce the original deviation from the set point.
   • C.An effector compares incoming information with the set point and decides which response is needed.
   • D.A receptor detects a change in a regulated variable and sends information to a control center.
   • E.The control center is always a gland, and the receptor is always a sensory neuron.

5. 5.A radiology report describes a mass located in the mediastinum, between the lungs. Which body cavity contains this region?

   • A.The pericardial cavity
   • B.The abdominopelvic cavity
   • C.The pleural cavity
   • D.The thoracic cavity
