egg chorion
|
UBERON_0000920 |

|
germ layer
|
UBERON_0000923 |
[A layer of cells produced during the process of gastrulation during the early development of the animal embryo, which is distinct from other such layers of cells, as an early step of cell differentiation. The three types of germ layers are the endoderm, ectoderm, and mesoderm.] |
|
endoderm
|
UBERON_0000925 |
[Primary germ layer that lies remote from the surface of the embryo and gives rise to internal tissues such as gut.] |
|
dorsal fin spine

median fin spine
|
UBERON_4200070 |
[Fin spine that is part of a median fin.] |
|
premaxillary-maxillary joint
|
UBERON_2002260 |
[Joint that articulates the premaxilla and maxilla. Premaxillary-maxillary joint is paired.] |
|
inter-premaxillary joint
|
UBERON_2001950 |

epineural 1
|
UBERON_2002263 |
|
|
epineural
|
UBERON_2000507 |
[Some or all epineural bones ossify free from the neural arches in most teleosts. In some lower teleosts, e.g., Leptolepis, Hiodon, elopiforms and albuliforms, ossification proceeds from the attachment point of the ligament to the arch, and the epineural is a process of the neural arch. In many lower teleosts epineurals are forked proximally.] |
|
anal fin spine
|
UBERON_2002262 |
|
|
pharyngeal branch of vagus nerve
|
UBERON_0000929 |
[Motor nerve of the pharynx, arises from the upper part of the ganglion nodosum, and consists principally of filaments from the cranial portion of the accessory nerve.] |
|

UBERON_2002265 |
|
|
obsolete embryonic segment

UBERON_0000928 |
|
|
epineural 2
|
UBERON_2002264 |
|
|
mesectoderm
|
UBERON_0000927 |
[A double row of cells which are located at the midline from the end of gastrulations. The morphology of these cells is distinct from adjacent ectodermal cells - they are elongated such that one end remains exposed to the outside of the embryo at the mideline while the other end bissects the internalised mesoderm.] |
