Silene invisa cyme of up to three flowers at the top of the stem. Each flower has a bell-shaped calyx of fused sepals lined with ten green veins and covered in short, glandular hairs. The strap-shaped or rectangular petals have blunt tips or may be notched. They are whitish to pinkish or lavender and sometimes barely protrude from the calyx. Silene invisa Silene invisa is a species of flowering plant in the pink family known by the common names red fir catchfly and short-petaled campion. It is endemic to California, where it is known only from the southernmost Cascade Range and northernmost
Calyx of Held and processing of the cochlear nucleus. Math1, another transcription factor, is necessary for the appearance of VCN neurons in the cochlear extramural stream as well as the neurons of the superior olivary complex. NB-2 also assists in the advancement of the formation of the calyx of Held, as well as contributing to the upkeep of the contralateral MNTB. The combined effects of these three molecules with one another illustrate the fact that there are many families of proteins involved in proper signaling and formation of the calyx. Additionally, Eph proteins are integral for further auditory circuit system development after initial
