Which of the following is true of the sacrum?
Back pain is one of the most common public health issues in Western developed communities, causing more global impairment than any other disease. 1 It imposes a significant social strain on individuals and the health-care system as a result of costs associated with lost working hours as well as medical services. 2 In the United States, direct annual medical expenditures on lower back pain reach $30 billion, far exceeding the cumulative costs of coronary artery disease, stroke, respiratory illness, rheumatoid disease, and diabetes. 3 The overall expense in the United Kingdom is projected to be €12 billion per year, while in the Netherlands it is 1.7 percent of GDP. 4 Lower back pain affects up to 80% of people at some point in their lives, with prevalence ranging from 15 to 45 percent and about 10% of patients being permanently disabled. 2,5 Degeneration of the intervertebral disc is closely linked to chronic back pain. 4, 5, and 6
Which of the following muscles is associated with back extension?
A matrix of living cells and a non-living material known as the ground substance make up connective tissues. An organic substance (usually a protein) and an inorganic substance make up the ground substance (usually a mineral or water). The fibroblast is the most important cell in connective tissues. Fibers are produced by this cell and can be found in almost all connective tissues. Fibroblasts are mobile, capable of mitosis, and capable of synthesizing any connective tissue required. Some tissues include macrophages, lymphocytes, and, on rare occasions, leukocytes. Specialized cells are present in some tissues but not in others. The matrix in connective tissues determines the density of the tissue. When a connective tissue has a high concentration of cells or fibers, the matrix density is proportionally lower.
Collagen, elastic, and reticular fibers are the organic component or protein fibers contained in connective tissues. Collagen fibers give tissue its resilience, preventing it from being torn or removed from its surroundings. Elastic fibers are made up of the protein elastin, which can extend to one-half its original length before returning to its original size and shape. Elastic fibers give tissues their versatility. The third form of protein fiber contained in connective tissues is reticular fibers. This fiber is made up of thin collagen strands that form a network of fibers that support the tissue and other organs to which it is attached. Table 1 summarizes the different types of connective tissues, the types of cells and fibers they are made of, and tissue sample locations.
Which of the following vertebrae is considered the strongest and most massive?
The vertebrae (bones), disks, nerves, and spinal cord are all important components of your spine. The spine is a structure that protects your body and allows you to walk, twist, and roll. A herniated disk occurs when the disks that cushion the vertebrae contract due to age or injury. Exercises can help reduce back injuries and discomfort by strengthening the core muscles that protect the spine.
The spine, also known as the backbone, is the basic support system of your body. It joins the various sections of your musculoskeletal system together. Your spine assists you in sitting, standing, walking, twisting, and bending. Back injuries, spinal cord disorders, and other issues can harm the spine and result in back pain.
Back muscles that are strong can strengthen your spine and help you avoid back problems. At least twice a week, do back-strengthening and stretching exercises. Planks, for example, reinforce the heart (abdominal, hand, and back muscles) to protect the spine. Your spine is a complex system of small bones (vertebrae), cushioning disks, nerves, joints, ligaments, and muscles, among other things. Injury, arthritis, herniated disks, pinched nerves, and other issues can affect this part of your anatomy. Back pain can make it difficult to enjoy life. Your doctor will help relieve back pain and give you tips on how to strengthen the muscles that support your back and avoid injuries.
Which of the following is considered the strongest and the thickest of the vertebrae?
Bones, joints, tendons, ligaments, muscles, nerves, and the spinal cord make up the spine, which is a complex anatomical structure. Your body’s basic structure, support, and flexibility are provided by your spinal column. A safe, well-functioning back is essential for mobility and the independent performance of daily activities.

The spine, also known as the backbone, is made up of vertebral bones that are separated by cushioning intervertebral discs. The spine is built to give us stability and smooth movement, as well as providing a corridor of protection for the fragile spinal cord. Muscles, tendons, and ligaments protect it, and nerves branching out from the central spinal cord provide innervation.
