FAQs on The Skeletal System, Joints & Muscular Disorders Video Lecture - Biology Class 11 - NEET

1. What is the function of the skeletal system?
Ans. The skeletal system has several functions, including providing support and shape to the body, protecting internal organs, producing blood cells, storing minerals such as calcium and phosphorus, and facilitating movement by providing attachment points for muscles.
2. What are joints and their role in the body?
Ans. Joints are the connections between bones. They allow for movement and provide stability to the skeletal system. Different types of joints, such as hinge joints, ball-and-socket joints, and pivot joints, allow for various types of movement, such as bending, rotating, and sliding.
3. What are some common muscular disorders?
Ans. Some common muscular disorders include muscular dystrophy, myasthenia gravis, fibromyalgia, and muscular sprains or strains. Muscular dystrophy is a genetic disorder that causes the progressive weakening of muscles, while myasthenia gravis is an autoimmune disorder that leads to muscle weakness and fatigue. Fibromyalgia is a chronic condition characterized by widespread muscle pain and tenderness. Muscular sprains or strains occur when muscles or tendons are stretched or torn.
4. How does exercise impact the skeletal system?
Ans. Exercise plays a crucial role in maintaining the health of the skeletal system. Weight-bearing exercises, such as walking or weightlifting, help in building strong bones and prevent conditions like osteoporosis. Additionally, exercise promotes joint flexibility and mobility, strengthens muscles that support the skeletal system, and improves overall posture and balance.
5. What are some common symptoms of muscular disorders?
Ans. Common symptoms of muscular disorders include muscle weakness, cramps, spasms, stiffness, pain, reduced range of motion, and difficulty in performing daily activities. Depending on the specific disorder, symptoms may vary in severity and can affect different muscles or muscle groups in the body. It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
