Questions doing with skeletal/muscular system?
Filed in Category Skeletal System Questions
001. Describe what one might have to do to cause a sprain.
002. Describe what one might have to do to cause a tendon to totally tear or develop tendonitis.
003. A person w/ a totally torn tendon will prevent a person from lowering his foot. Muscles contract when they work. The Gastrocnemius shortens & pulls the foot down. Migt the foot be raised if the Achilles tendon is totally torn? Why? Might a person with a totally torn Achilles tendon still e able to move his leg? Why?
Haha, actually , I only need #3 now. I get 1 & 2.

1. A sprain is nothing more than an injury which occurs to ligaments caused by a sudden overstretching, In other words, over working a certain ligament in a target skeletal location. Remember that ligaments are connective tissue, that connect bone to bone.
2. A tendon is the end part of a muscle that attaches the muscle to the bone. The normally very elastic and soft muscle tapers off at the end to form the much more dense and stiff tendon. While this density makes the tendons stronger, the lack of elasticity of the tendon and the constant pulling on its attachment to the bone with movement, makes it much more susceptible to a low level of tearing at a microscopic level. This tearing will produce the inflammation and irritation known as tendinitis. Tendinitis is usually seen after excessive repetitive movement with which the tendon gradually becomes tighter until the fibers start to tear.
3. Te third question am not really getting what you’re asking. But what I can tell you is. If the achilles tendon is totally torn, it is quite hard to raise your foot as the point of insertion for that muscle has been totally damaged, the muscle will try to work as a lever. However the leg can still be moved, due to neurological stimulation to the skeletal muscle, and is the action of walking itself that has been damaged.
Hope this helps =]
