1. Where is the ball-and-socket joint, allowing a wide range of motion, found?

Correct answer: A

Rationale: The ball-and-socket joint is located between the upper arm (humerus) and the shoulder blade (scapula). This joint provides a wide range of motion, enabling movements like flexion, extension, abduction, adduction, and rotation. It plays a crucial role in various activities involving the shoulder joint, such as throwing, reaching overhead, and performing rotational movements. Choice B, the collarbone (clavicle) and breastbone (sternum), form the sternoclavicular joint, which is a synovial saddle joint. Choice C, two vertebrae in the spine, typically form gliding or facet joints. Choice D, ribs and sternum, are connected by cartilage, forming cartilaginous joints.

2. Urinary system health can be maintained through various lifestyle practices. Which of the following is NOT recommended for optimal urinary system health?

Correct answer: C

Rationale: Holding urine in the bladder for long periods is not recommended for optimal urinary system health. It can increase the risk of urinary tract infections and other bladder-related issues. When urine is held for a long time, bacteria have more time to multiply in the bladder, leading to infections. Additionally, holding urine for prolonged periods can also contribute to bladder distension, which may affect bladder function over time. Therefore, it is crucial to empty the bladder regularly to maintain good urinary system health. Limiting high-sodium foods helps reduce the risk of kidney stones and high blood pressure, while consuming cranberry juice may help prevent urinary tract infections by interfering with the adhesion of bacteria to the bladder walls. Regular moderate-intensity exercise promotes overall health, including maintaining a healthy weight and reducing the risk of chronic conditions that can impact the urinary system.

3. Which of the following is not a biological macromolecule?

Correct answer: D

Rationale: Glucose is a monosaccharide, which is a simple sugar and not a macromolecule. Glycoproteins, DNA, and phospholipids are all examples of biological macromolecules. Glycoproteins are proteins covalently bonded to carbohydrates, DNA is a nucleic acid, and phospholipids are lipids that contain a phosphate group.

4. In which group of the periodic table are alkali metals located?

Correct answer: A

Rationale: Alkali metals, such as lithium, sodium, and potassium, are located in Group 1 of the periodic table. This group is known for its highly reactive properties, low melting points, and the tendency to form alkaline solutions when they react with water. Group 2 consists of alkaline earth metals and not alkali metals, making choice B incorrect. Group 7 includes halogens, while Group 8 includes noble gases. These groups do not contain alkali metals, so choices C and D are also incorrect. Therefore, the correct answer is Group 1.

5. Which types of glial cells are found in the CNS?

Correct answer: B

Rationale: The correct answer is B. Glial cells in the CNS include astrocytes, microglia, ependymal cells, and oligodendrocytes. Schwann cells and satellite cells are found in the PNS. Astrocytes are the most abundant type of glial cells and are involved in nutrient support, repair, and maintenance of the extracellular environment. Microglia are the resident immune cells of the CNS, playing a role in immune defense. Ependymal cells line the ventricles of the brain and the central canal of the spinal cord, contributing to the production and circulation of cerebrospinal fluid. Oligodendrocytes are responsible for producing myelin, which insulates axons in the CNS. Understanding the specific functions of each type of glial cell is essential in grasping the complexity of the central nervous system's support and protective mechanisms.
