- Paraplegia is diagnosed in the patient with lower limb paralysis after a motorcycle accident. Hence the correct option is d.
- Blood moves through arteries, arterioles, capillaries, venules, and veins, starting from the heart. Hence the correct option is c.
- Myalgia is the term for muscle pain. Hence the correct option is b.
- Osteocytes are a type of cartilage cells. Hence the correct option is c.
- There are 12 pairs of false ribs. Hence the correct option is a.
- Damage to a ligament results in a strain.
- Both voluntary muscle and cardiac muscle contain striations. Hence the correct option is d.
1. Paraplegia is diagnosed when a patient exhibits paralysis in the lower two limbs. In this case, after a motorcycle accident, the individual experiences a loss of motor function below the waist, indicating damage or impairment typically to the spinal cord in the thoracic or lumbar region. This condition contrasts with quadriplegia, where paralysis affects all four limbs. Hence the correct option is d.
2. Blood moves through the circulatory system in a specific sequence, starting from the heart. The correct sequence is arteries, arterioles, capillaries, venules, and veins. Arteries carry oxygenated blood away from the heart, branching into arterioles and then capillaries where nutrient and gas exchange occurs. Subsequently, the blood travels through venules and veins back towards the heart. Hence the correct option is c.
3. Myalgia is a term used to describe muscle pain. It can result from various causes, such as overuse, injury, or infection. When individuals experience discomfort or pain in their muscles, often associated with conditions like fibromyalgia or muscle strain, it is referred to as myalgia. Hence the correct option is b.
4. Osteocytes are specialized cells found in bone tissue. These cells play a crucial role in maintaining bone health by regulating mineral content and participating in the repair and remodeling processes. Osteocytes are embedded within the bone matrix and communicate with each other to coordinate bone homeostasis. Hence the correct option is c.
5. There are 12 pairs of false ribs in the human ribcage. False ribs are those that do not directly attach to the sternum but may connect indirectly or remain unattached in the case of floating ribs. Hence the correct option is a.
6.Ligament damage typically results in a strain. Ligaments are fibrous tissues that connect bones to each other, and when subjected to excessive stretching or tearing, it leads to a strain. Strains are common injuries that can occur in various parts of the body, often due to overexertion or sudden movements.
7. Both voluntary muscle (skeletal muscle) and cardiac muscle contain striations. Striations are alternating dark and light bands observed under a microscope, reflecting the arrangement of contractile proteins in muscle fibers. While voluntary muscle is under conscious control, cardiac muscle is involuntary and found in the heart, contributing to its rhythmic contractions. Hence the correct option is d.
