The musculoskeletal system provides mechanical support for the body, protects internal organs and permits movement. It is composed of bones, cartilage, skeletal muscles, joints, and connective tissues such as tendons and ligaments. Bones also serve as the body’s main mineral reservoir, they store calcium and phosphate and release them according to the body’s needs. Red bone marrow is the body’s production center for blood cells.
The central nervous system controls body movements by stimulating skeletal muscles to contract. Contraction of skeletal muscles moves bones, which act as levers. Bones articulate with each other through joints. Cartilage provides padding for the ends of bones within joints. Muscles are connected to bones by tendons, while bones are held together by ligaments.
Bones are classified according to their shapes and corresponding functions: long bones are responsible for most body movements; short bones provide some limited motion; while flat bones and irregular bones are mainly protective and supportive.
The bone tissue, or osseous tissue, is composed of bone cells and a characteristic extracellular matrix. Bone matrix is made of an organic component, mainly collagen, and an inorganic component of minerals, mainly calcium. Collagen gives bones flexibility while calcium provides stiffness. Without calcium, bones would be soft and bend easily. On the other hand, without collagen, bones would be brittle like chalk.
Bones renew and remodel throughout a person’s life in a process known as bone remodeling. Bone remodeling serves to re-shape bones to adjust to changing mechanical needs and to repair everyday micro-damages as well as fractures following injuries. This process also underlies the mechanism by which the constant levels of plasma calcium and phosphate are maintained. Bone remodeling is performed by 2 types of cells: osteoclasts, which dissolve bone matrix, and osteoblasts, which deposit new matrix around themselves to form new bone tissue. Bone remodeling is under control of complex signaling pathways. Major regulators include parathyroid hormone, vitamin D, growth hormones, glucocorticoids, thyroid hormones, estrogen, testosterone.
The most common bone disease is osteoporosis, or porous bone, in which bones lose mass and weaken, increasing risks of fractures. Osteoporosis is commonly due to old age and some other unavoidable factors, but can also develop from by hormone imbalances, deficiencies in calcium, vitamin D or proteins, and sedentary lifestyles.
The most common and also most movable type of joint is synovial joint. The bones of a synovial joint are separated by a cavity containing synovial fluid, which serves as lubricant. Together, the fluid and the cartilage that lines the bone surfaces make the movements at synovial joints almost friction-free. There are also small fibrous sacs containing synovial fluid, called bursae, located between muscles, or between a tendon and a bone. Bursae cushion muscle movements and help tendons slide smoothly over the joints.
The most common disease of joints is arthritis. There are 2 main types of arthritis:
Osteoarthritis, or degenerative joint disease. Osteoarthritis is characterized by loss of cartilage, bone spurring and no major inflammation.
Rheumatoid arthritis is a result of joint inflammation, with immune cells and inflammatory chemicals causing damage to the joint.
Muscular tissue consists of specialized muscle cells, called muscle fibers, which are bundled into fascicles. Muscle fibers, fascicles and whole muscles are wrapped in layers of connective tissue, which provides support and protection. Fascicle arrangement determines the strength of a muscle and the direction it pulls. Most common muscle disorders are caused by injury or overuse, and include sprains, strains, cramps, and tendinitis.
Love this video? Check out our course “Anatomy and Physiology” made entirely with videos like this (without watermark): www.alilaacademy.com/courses/anatomy-and-physiology-for-teachers
how did she explain everything you need to know about the musculoskeletal system in 5 minutes & nailed it, i dont know, absolutely amazing!
I am teaching this to Middle Schoolers and this is perfect for them. It lays out the basics clearly for them and talks about things they will encounter in their real life (like sprains/strains and arthritis.
My teacher is teaching them to us, too. And we're high schoolers
@@wetershinobi4111 college lmaoooooo
I learn this in uni - Medicine 🤣
I had a test on this , I forgot to study , I watched this video and i got a 100 thank you 💕
😅who got test tomorrow
Clever bastard. You got me😂
Bone OSCE tomorrow😂 but I studied. Just making sure I didn't leave anything out
🤣
@@thewhiteknight9923 as true as fuck 😜😜
🙈
Today, actually😂
So this is why my neck hurts and my kidneys started failing again. I'll be dogone. That's why blood work shows low co2, and i bet this why my sinuses are acting up. And why im always couching up phlegm. Im about to start tapping my mouth at night so i can breathe through my nose to increase co2 and do breathing exercises throughout the day. I believe my vision is affected by all this too. So amazing the way the human body is connected. Thanks for the information ❤❤
Yes! Keep popping out overviews
thank you so much i understand this course in 5 minutes
Thank you, this taught me alot in science
omg i love your content
You're very welcome!
Very good summary
Thank you for giving me your important time 😊
Good job.
😊I’m teaching this today in my medical school
You happen to know how to better it? Thx
Great video to start MSK block. Thanks
Excellent lecture
Owhh asignment..saya berada disini sebb tugasan🤗
Absolutly amazing this’ll be usefull for my quiz. You nailed!👏
So glad!
Its our topic tomorrow in science thx for the tips 😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁😁
Very Informative and easy to understand
- Ignore this comment 🔥🔥
1. What are the main function of Muscockeletal System?
2. What part of the body is reaponsible for the production of blood cells?
3. Write the function of the following parts:
• Joints =
• Tendon =
• Cartilage =
• Ligaments =
• Synovial Joint =
4. What are the different classification of bones?
5. What are the different disorders or diseases under Muscoskeletal System?
That's sounds great as good video
I find this very useful
You guys are my life saver! ❤
im learning so much
Thnks to you Alila Medical Media i love your videos
😢
This is amazing thank you so much
Awesome...👍👍👍
wonderful video. nutshell explanation

Wow! What a Save! What a Save!
Thank you it helped me !
Most helpful
Helpful
Nice understand
Thank you useful
No body got test tomorrow
Is there ways to fix or better your muscle skeleton system?
Awesome
middle school science teacher assinged me this video. using my own yt account bc the district blocked school emails from yt commenting or the comments on a yt video.
Kinsa mga taga CMU diri nga ga-tan-aw ani para quiz nila's PE?
Nice
Please muscle physiology
For me it is hard to understand because I know only hindi....but still I watch videos in slow speed and can understand 😰😰😰
Hello, do you go too college or university? I am a University nursing student. If you give me your email then I'll can send you notes on the musculoskeletal system. They will be in english though. I don't know hindi but i know punjabi and urdu which is similar to hindi. I can understand hindi but i cant speak it or write it. I am using google translate to put this comment into hindi so u can understand what I am saying.
