Kaslar - Muscle
http://frmsinsi.net/attachment.php?a...1&d=1330884289 Kas-iskelet sisteminin dış ve iç kasla genişleyip kasılarak eklemlerin hareket etmelerini sağlarlar. Bu kasların hepsi çifttir. Örneğin; biceps kaslarının kasılmaları kolunuzun üst kısmının bükülmesini sağlar, diğer taraftan karşıt triceps kaslarının kasılması kolunuzu uzatır. Kasların pek çoğu tendonlarla kemiklere bağlıdırlar. Did you know you have more than 600 muscles in your body? They help you do almost everything — from pumping blood throughout your body to lifting your heavy backpack. You control some of your muscles and others, like your heart, do their jobs without you thinking about them at all. Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle. You have three different types of muscles in your body: smooth muscle, cardiac (say: kar-dee-ak) muscle, and skeletal (say: skeh-luh-tul) muscle. |
