Responsiveness- is a property of all living cells- Muscle and nerve cells have developed this property to the highest degree. When stimulated by chemical signals‚ stretch‚ and other stimuli‚ muscle cells respond with electrical changes across the plasma membrane. b. Conductivity- Stimulation of a muscle cell produces

One of the most complex joints in the human body is the knee as it connects the femur and tibia. Anterior cruciate ligament is one of the four major ligaments in the knee. The role of a knee is evident not in only stabilising the body but also from everyday activities such as walking‚ running‚ sitting and performing sports. It is sufficed to say that the most common injuries in our body is knee injuries as it is very common in the sports world. Rupturing the anterior cruciate ligament is the most

nerves. I am going to talk about the joints of the skeletal system. The skeletal system gives us our shape and protects the inner structures of our bodies. In this system there are areas where 2 or more bones are held together in one of three ways. These are called joints and the bones and movement of the bones classifies the type of joint that is in that particular area.

Hinge joints A hinge joint is the simplest type of joint. It is found in the elbows and the joints of the fingers and toes. Hinge joints allow movement in only one direction. The hinge joint of the knee‚ the body’s largest joint‚ is unusual because it can swivel on its axis‚ allowing the foot to turn from side to side. Therefore‚ the knee is constantly rolling and gliding during walking. Gliding joints Gliding joints are the surfaces that are flat or slightly curved. These joints allow sliding

the stability of the knee joint. The ACL specifically prevents the tibia from sliding too far forward‚ making the joint unstable and prone to dislocation. When someone experiences an injury to the ACL‚ they often complain of the feeling that their knee will “give out” due to the lack of stability of the knee joint when the ACL is torn. An ACL injury makes the knee more prone to arthritis and cartilage tears. When you tear your ACL‚ you might hear or feel a pop in your knee. There will probably
