Anatomy
1. Cartilage, a type of connective tissue, provides flexible support in various structures. Which of these does NOT contain cartilage?
- A. Ears
- B. Joints
- C. Muscles
- D. Nose
Correct answer: C
Rationale: Muscles do not contain cartilage. Cartilage is a specialized type of connective tissue that provides flexible support in structures like the ears, joints, and nose. Ears have cartilage in their structure, which helps maintain their shape and flexibility. Joints, such as the knee and elbow, have cartilage to cushion and reduce friction between bones. The nose also contains cartilage, forming its shape and structure. Muscles, on the other hand, are made up of muscle tissue and do not contain cartilage. Therefore, muscles are the correct answer as they do not contain cartilage, unlike the other options.
2. The body's first line of defense against pathogens is the innate immune system. Which of the following is NOT a component of the innate immune system?
- A. Physical barriers like skin and mucous membranes
- B. Phagocytes that engulf and destroy pathogens
- C. Inflammatory response to isolate and contain infection
- D. Production of antibodies specific to a particular pathogen
Correct answer: D
Rationale: The innate immune system is the body's first line of defense against pathogens and includes physical barriers like skin and mucous membranes, phagocytes that engulf and destroy pathogens, and the inflammatory response to isolate and contain infection. However, the production of antibodies specific to a particular pathogen is a function of the adaptive immune system, not the innate immune system. The innate immune system provides immediate, nonspecific defenses, while the adaptive immune system generates specific responses to target pathogens. Therefore, option D is NOT a component of the innate immune system, making it the correct answer in this question.
3. What is the correct way to punctuate the following sentence: "She asked me if I wanted to go to the movies with her"?
- A. She asked me, if I wanted to go to the movies with her.
- B. She asked me: if I wanted to go to the movies with her?
- C. She asked me, if I wanted, to go to the movies with her.
- D. She asked me if I wanted to go to the movies with her.
Correct answer: D
Rationale: Option D uses a question mark within the quoted material as it is a direct question.
4. What is the difference between a ventral and dorsal root of a spinal nerve?
- A. Ventral carries motor, dorsal carries sensory information.
- B. Ventral carries sensory, dorsal carries motor information.
- C. Ventral is larger, dorsal is smaller.
- D. Ventral is located anteriorly, dorsal is posteriorly.
Correct answer: A
Rationale: The correct answer is A: 'Ventral carries motor, dorsal carries sensory information.' Ventral roots of spinal nerves contain motor fibers that carry signals from the central nervous system to muscles and glands, controlling movement and function. Dorsal roots, on the other hand, contain sensory fibers that transmit information such as touch, pain, and temperature from the peripheral nervous system to the central nervous system for processing. Understanding this distinction is crucial for comprehending how information is transmitted and processed in the nervous system.
5. Which sentence avoids a dangling modifier?
- A. Walking down the street, a bird swooped down from a tree.
- B. Having finished the report, it was time for lunch.
- C. Reading the book, I learned a lot about ancient history.
- D. Exhausted from the hike, the tent was a welcome sight.
Correct answer: C
Rationale: Option C places the participle phrase "Reading the book" in front of the subject "I," eliminating the dangling modifier.
6. What is the medical term for heartburn, a burning sensation in the chest caused by stomach acid?
- A. Dysphagia
- B. Gastroesophageal reflux disease (GERD)
- C. Peptic ulcer
- D. Ulcerative colitis
Correct answer: B
Rationale: Rationale: A) Dysphagia refers to difficulty swallowing and is not specifically related to heartburn. B) Gastroesophageal reflux disease (GERD) is the medical term for heartburn, which is a burning sensation in the chest caused by stomach acid flowing back up into the esophagus. C) Peptic ulcer is a sore that develops on the lining of the stomach, small intestine, or esophagus, and it can cause symptoms such as abdominal pain, not specifically heartburn. D) Ulcerative colitis is a type of inflammatory bowel disease that affects the colon and rectum, and it does not typically cause heartburn.
