3.C 细节题。根据第二段前3行The skeletal muscles are attached to the bones; they actually hold the skeleton together. Strong cords, called tendons(肌腱), help connect these muscles to the bones.说明The skeletal muscles是通过肌腱来和骨头相连的,故C项正确。
All the bones in our body make up our skeleton– from the top of our skull to the tips of the phalanges at the end of our toes.Muscles stretch across our bones and are attached with tendons. We use both our muscles and our skeleton to stand, write and even turn the pages when we’...

Muscles are attached to bones by tendons andhelp them to move. When a muscle contracts (bunches up), it gets shorter and so pulls on the bone it is attached to. When a muscle relaxes, it goes back to its normal size. Muscles can only pull and cannot push. ...
A chapter of the book "How Muscles and Bones Hold You Up: A Book About Models," by Marcia S. Freeman is presented, which focuses on the role of muscles and tendons in human movements. Ligaments hold bones together, but muscles make them move. Muscles are attached to bones by tendons. ...
Some muscles are attached to bones by tendons. Others are attached to other muscles, or to skin (producing the smile, the wink, and other facial expressions, for example). All or part of the walls of hollow internal organs, such as the heart, stomach, intestines, and blood vessels, are...
elastic tissues and are flexible and they work like a rubber band. Some muscles attach to your bones bytendonshelping the skeleton to move by relaxing and contracting them. When the muscle contracts, the muscles bulge like biceps, and when they relax, they return back to their original state...
Muscle is the fibrous tissue in the body that has the ability to contract (when asked to do so by the brain). When a muscle contracts, it shortens (becomes smaller). Muscles are attached to the bones of our skeleton (through strong fibres called tendons). So, when the muscle attached ...
Voluntary muscles are found attached to bones by means of tendons.Involuntary musclesare found lining the walls of internal organs like the stomach, intestine, urinary bladder, and blood capillaries. Are biceps voluntary or involuntary? Voluntarymuscles are skeletal muscles that attach to bones and ca...
