About Carnegie Stage 14

Most embryos at stage 14 are approximately 32 postovulatory days old and measure 5-7 mm in length. Distinguishing criteria for this stage include an open lens pit with invagination of the lens disc and elongated and tapering upper limb buds. The otic vesicle with a well-defined endolymphatic appendage is also a hallmark of this stage.
