| 설명 | 모든 척삭 동물 몸의 일차 긴뼈축을 형성하는 것으로 신경관 밑에서 발달하는 배아기 뒤쪽 표면을 따라 확장하고 1차 결절에서 발생하는 중배엽 조직의 긴띠. 원착동물에서는 일생동안 볼 수 있으나, 척추동물에서는 퇴화된다. 비록 이것의 잔여물이 척추원반의 속질핵의 한부분으로 남아 있다 하더라도 인간과 다른 척추동물에서 이 구조는 척추로 대체된다. |

| notochord | <embryology> An axial mesodermal tissue found in embryonic stages of all chordates and protochordates, often regressing as maturity is approached. Typically a rod shaped mass of vacuolated cells. It lies immediately below the nerve cord and may provide mechanical strength to the embryo. (13 Nov 1997) |

| notochord |
a continuous dorsal rod of cartilaginous material running from the head to the tail. This is perhaps the "defining" characteristic of the chordates. In more derived forms, the notochord is excluded from the head and may become discontinuous, its structural function assumed by serial ossifications, ie the vertebrae.
