1. Tissues are groups of cells with similar:
- A. Appearance only
- B. Function and structure
- C. Location only
- D. Age only
Correct answer: B
Rationale: Tissues are groups of cells that work together to perform a specific function. They have similar structures that enable them to carry out their specialized functions effectively. Therefore, tissues are defined by both their function and structure, making option B the correct choice. Choices A, C, and D are incorrect because tissues are not solely defined by their appearance, location, or age, but rather by the shared function and structure of the cells within them.
2. Which of the following is NOT a function of the integumentary system?
- A. Regulation of body temperature
- B. Protection from pathogens
- C. Synthesis of vitamin D
- D. Production of digestive enzymes
Correct answer: D
Rationale: The correct answer is D. The production of digestive enzymes is not a function of the integumentary system. The integumentary system is responsible for regulating body temperature, protecting the body from pathogens, and synthesizing vitamin D. Digestive enzymes are produced by organs in the digestive system, such as the pancreas and stomach, and not by the integumentary system.
3. Which of the following is an example of the location and function of cartilage in the body?
- A. The dense connective tissue that makes up the majority of the structural skeleton
- B. The supportive pads that provide cushioning at joints, such as between the vertebrae of the spinal cord
- C. The connective structure made of fibrous collagen that connects muscles and bones
- D. The layer beneath the skin and on the outside of internal organs that provides cushioning and protection
Correct answer: B
Rationale: Cartilage is a type of flexible connective tissue that acts as supportive pads providing cushioning at joints, like those found between the vertebrae of the spine. This specific function of cartilage helps in reducing friction and absorbing shock in these areas, contributing to joint flexibility and protection. Choices A, C, and D do not accurately describe the function and location of cartilage in the body. Option A incorrectly refers to dense connective tissue, which is different from cartilage. Option C describes tendons or ligaments, which are not cartilage. Option D refers to adipose tissue, which is a type of connective tissue that stores fat and provides insulation, but it is not cartilage.
4. In which regions of the digestive system is amylase produced?
- A. pancreas and salivary glands
- B. gall bladder and salivary glands
- C. gall bladder and liver
- D. pancreas and liver
Correct answer: A
Rationale: Amylase is an enzyme that breaks down carbohydrates into smaller sugars. It is produced in the pancreas and salivary glands. The salivary glands release amylase into the mouth during chewing, where it initiates the breakdown of carbohydrates. The pancreas also secretes amylase into the small intestine to further assist in carbohydrate digestion. Choices B, C, and D are incorrect as the gall bladder does not produce amylase, and the liver's primary function is not the production of amylase for carbohydrate breakdown.
5. Which part of the brain is responsible for balance and coordination?
- A. Cerebrum
- B. Cerebellum
- C. Medulla oblongata
- D. Thalamus
Correct answer: B
Rationale: The correct answer is the cerebellum. The cerebellum is responsible for balance, coordination, and fine motor control. It integrates sensory information from the vestibular system in the inner ear and proprioceptive information from muscles and joints to coordinate voluntary movements. The cerebrum is primarily involved in higher brain functions like thinking and decision-making. The medulla oblongata controls vital autonomic functions such as breathing and heart rate. The thalamus serves as a relay station for sensory information before sending it to the cerebral cortex for further processing.
