Introduction to Anatomy and Physiology Lesson 1.1 Study Questions Questions
Question 1 of 5
The foot is to the thigh as the hand is to the:
Correct Answer: A
Rationale: The foot is distal to the thigh (femur); the hand is distal to the brachium (A, upper arm), not shoulder, palm (C, hand part), or digits. Anatomically, this analogy tracks limb segments hand below elbow mirrors foot below knee making A apt.
Question 2 of 5
Give the proper sequence of body cavities or areas traversed as blood flows from the heart to the uterus through the aorta and the uterine artery:
Correct Answer: B
Rationale: Blood flows from heart (pericardial, mediastinal in thoracic) via aorta (mediastinal) to abdominal (descending aorta), then pelvic (uterine artery). Options A, C, D misorder or include pleural (lungs). Anatomically, this traces vascular path thoracic to pelvic matching circulation, confirming B.
Question 3 of 5
Acids are best considered to be:
Correct Answer: B
Rationale: Acids are proton (Hâº) donors 's acid' definition, releasing H⺠in solution e.g., HCl. Bases accept Hâº, buffers stabilize pH, and proton acceptors misalign. Anatomically, this impacts pH balance e.g., lactic acid in muscles lowers pH crucial for cellular function, making B correct.
Question 4 of 5
The nurse is teaching a client about bone fractures. The nurse explains that the type of cells present in the bone matrix are referred to as:
Correct Answer: A
Rationale: Osteoblasts form bone matrix, depositing collagen and minerals, per options 5-8. Fibroblasts make connective tissue, chondroblasts cartilage, hemocytoblasts blood cells. Anatomically, osteoblasts build compact bone, essential for fracture healing, confirming A.
Question 5 of 5
The nurse is teaching a client how the heart works. When explaining that the heart's contraction is caused by electrical stimulation, the nurse recalls that which type of tissue generates electrical signals?
Correct Answer: A
Rationale: Nervous tissue generates electrical signals (e.g., via cardiac pacemaker cells), per options B5-B8, triggering heart muscle contraction. Epithelial covers, connective supports, muscle contracts not signals. Anatomically, the sinoatrial node (nervous) initiates beats, making A correct.
