첫댓글 선생님~
2번에 양극세포도 신경세포인데 양극시포부터 활동전위거 발생하는거 아닌가요~?
양극세포에선 수용기 전위만 발생하고 활동전위는 발생하지 않습니다.
@홍장군고양이 답변 감사합니다~!
저는 시각수용체에서는 수용기 전위가, 신경세포에서는 활동전위가 발생한다고 공부한거 같아서 양극세포는 시각수용체가 아니라 신경세포라 활동전위가 발생하는 줄 알았는데ㅠ
혹시 제가 어떤 점을 잘못 생각 하고 있는지 궁금합니다
@생물쌤2021 총론에 망막에서 실무율의 활동전위를 생성하는 뉴런은 신경절세포와 무축삭세포이다. 광수용기세포, 양극세포, 그리고 수평세포는 차등성 전위를 생성하여 탈분극 돠거나 과분극 된다. 라고 적혀있네요~
