FAQs on Muscular System - Biology, General Science Video Lecture - SSC CGL Tier 2 - Study Material, Online Tests, Previous Year

1. What are the main functions of the muscular system?
The main functions of the muscular system include providing movement and stability to the body, generating heat to maintain body temperature, protecting internal organs, and assisting in the circulation of blood and lymph fluids.
2. How many muscles are in the human body?
There are over 600 muscles in the human body. These muscles are categorized into three types: skeletal muscles, smooth muscles, and cardiac muscles.
3. How do muscles contract and relax?
Muscles contract and relax through a process called sliding filament theory. When a muscle receives a signal from the nervous system, calcium ions are released, enabling the actin and myosin filaments within the muscle fibers to slide past each other. This sliding action shortens the muscle and causes it to contract. To relax, the calcium ions are pumped back into storage, allowing the actin and myosin filaments to separate and the muscle to return to its original length.
4. How does exercise affect the muscular system?
Exercise has numerous positive effects on the muscular system. It helps to increase muscle strength, endurance, and flexibility. Regular exercise also promotes the growth and development of muscles, improves muscle tone, and enhances overall muscle performance. Additionally, exercise stimulates the production of hormones that support muscle growth and repair.
5. What are some common muscular system disorders?
Some common muscular system disorders include muscular dystrophy, fibromyalgia, muscle strains and sprains, and myasthenia gravis. Muscular dystrophy is a group of genetic disorders characterized by progressive muscle weakness. Fibromyalgia is a chronic condition that causes widespread muscle pain and tenderness. Muscle strains and sprains occur when muscles or tendons are overstretched or torn. Myasthenia gravis is an autoimmune disease that leads to muscle weakness and fatigue.
