본문/내용
4. 기능 : 근육은 어떻게 작용하는 것인가? 최근 해부학자들의 연구방법은 운동을 하고있는 근육을 관찰하기 위해 근육의 조직 또는 근육구조의 지식을 통한 운동의 추론으로부터 근전도를 사용한 새로운 복잡한 방법으로 변하고 있다. 골격근은 각 관절 주변에서 단독으로보다는 주로 그룹으로 수축해서 관절에 대한 행위를 한다. 근육이 관절을 가로질러 있으면서 움직임을 일으키는데 이 운동을 그 근육의 수축이나 근육의 위치에 따른 기능적 평가에 적합하게 일으키는 것이다. 많은 골격근 기능을 이해 하기 위해서는 근수축의 분류나 그에 관련된 사항들의 비교분석 등 몇가지를 알지 않으면 안된다. 따라서 이부분에서는 근육의 수축에 대해 이해하는 것이 가장 우선한다고 생각된다.
(1) 기본원칙
1) 골격근은 자극받았을 때에만 수축한다 : 골격근은 심근과 내장근처럼 자동적으로 작용하는 특성은 가지고 있지 않다. 신경자극은 설사 골격근에 있어서 자연적인 자극이든 전기적 자극이든, 또는 다른 인공적인 자극일지라도 근육을 활동적으로 수축하도록 할 수가 있다. 어떤 이유에 의해 신경자극이 저해된 골격근은 기능을 상실한 근육의 덩어리에 지나지 …(생략)
