Biology
Tutor: None Selected Time limit: 0 Hours

Using the words Cartilage, Muscles, Tendons, Bones, Joints, and Ligaments...explain how a human arm moves in complete sentences.

Mar 11th, 2015

When you bend your elbow, the muscle pulls (contracts). Then the muscle pulls on tendon, which is attached to the skin bone to extend the elbow joint and straighten the arm. During that action, ligament between your bones of elbow serves as a caution and allows an elastic movement of your joints. At the same time, cartilage between those bones is serving as a shock absorber during this whole movement process.

attached to the skin bone? what is a skin bone?


Mar 11th, 2015

the bone is covered with the specific layer of skin and calls skin bone...

"the muscle pulls tendon" this sentence doesnt make sense.

Ok, then, leave it alone!! Ask another tutor. 

Mar 11th, 2015

sorry it just is confusing


Mar 11th, 2015

sorry but one more question what does shock absorber mean

Mar 11th, 2015

a layer that prevents direct contact between bones - otherwise bones would rub against each other and wear off with time. Absorbing shock literally means a decrease/prevention in hard motion/hit/wave
