숨뇌 [연수]
Myelencephalon; Medulla oblongata
정의
숨뇌[연수]는 마름뇌(후뇌)의 꼬리쪽 하위구분으로, 숨뇌[연수]로 발달합니다. 숨뇌[연수]는 앞쪽의 뒤뇌와 뒤쪽의 척수 사이에 위치하며, 뇌줄기의 꼬리쪽 부분을 형성합니다.
숨뇌[연수]는 꼬리쪽으로 큰구멍 수준에서 척수와 연속되며, 등쪽으로는 넷째뇌실 바닥의 일부를 형성합니다. 숨뇌[연수]에는 오름감각로, 내림운동로, 그물체 핵, 자율중추, 그리고 여러 뇌신경, 특히 제VIII에서 제XII 뇌신경과 연합된 핵이 포함되어 있습니다.
기능적으로, 숨뇌[연수]는 척수와 상위 뇌중추 사이의 정보 전달에 관여하며, 호흡, 심혈관 조절, 내장반사 활동을 포함한 생명유지 자율기능의 조절에도 관여합니다.
