Scoliosis

Answer 34

abnormal sideways curvature of the spine, often forming an "S" or "C" shape.

Question 35

Kyphosis

Answer 35

(Posterior curves) an excessive outward curvature of the spine, leading to a rounded or hunched back posture, often seen in the thoracic region.

Question 36

Lordosis

Answer 36

(Anterior curves) an excessive inward curvature of the spine, creating an exaggerated arch, typically observed in the cervical or lumbar regions.

Question 42

Arthritis

Answer 42

Inflammation of one or more joints, leading to pain, swelling, and reduced joint mobility.

Question 43

Osteoporosis

Answer 43

Characterized by weakened bones, increasing the risk of fractures due to loss of bone density and strength.

Question 44

Dislocation

Answer 44

Occurs when the ends of two connected bones are forced out of their usual positions at a joint, causing pain and loss of joint function.

Question 45

Sprain

Answer 45

An injury to a ligament, the tissue that connects bones to each other at a joint, often caused by overstretching or tearing, resulting in pain and swelling.

Question 46

Yellow marrow

Answer 46

(fat)/ yellow marrow is found in medullary cavity in adults
