| 영문 | smooth muscle | 한글 | 민무늬근육, 평활근육 |
|---|---|---|---|
| 설명 | 근육 중에서 가로무늬가 없는 근. 가로무늬근에 대응되는 말이다. 척추동물에서는 심장근 이외의 내장근은 모두가 민무늬근이다. 많은 내장장기의 벽에 분포되어 있으며, 대개 돌림층과 세로층의 두 층으로 배열되어 있다. 소화관이나 요관 같은 관모양의 구조에서는 꿈틀운동을 일으켜 내용물이 아래로 내려가게 하는 작용을 한다. 항문관, 위, 요도 등에서는 돌림층의 근육이 특히 두꺼워져 내용물이 내려가는 것을 조절하는 조임근육이 형성되어 있다. 혈관에는 돌림층만 있으며, 혈관을 수축하여 혈액을 쥐어짜는 작용을 한다. 또한 자율신경의 지배를 받으며, 우리의 의지와 관계없이 작용한다. |

| 영문 | voluntary muscle | 한글 | 수의근 |
|---|---|---|---|
| 설명 | 의지의 힘으로 움직일 수 있는 근육. 골격근 외에 피부 내의 피근, 관절주머니에 부착하고 있는 관절근 등이 여기에 속한다. 수의근의 근섬유에는 가로무늬가 있으므로 가로무늬근이라고도 하나, 심장근은 가로 무늬가 있어도 수의근이 아니므로 수의근과 가로무늬근은 동의어는 아니다. 수의근의 운동은 민무늬근보다 빠르다. 수의근이라 해도 골격근 등은 근육무리로서 움직일 수 있으나, 개개의 근육은 따로따로 마음대로 움직이게 할 수 없다. 귓바퀴근육은 사람의 경우 발육이 나빠 마음대로 움직이게 하기 어렵다. |
