Stellaria umbellata inflorescence is an umbel-shaped array of several flowers each on an arching or erect pedicels. The flower has five pointed green sepals each no more than 3 millimeters long. There are occasionally tiny white petals within the calyx of sepals, but these are generally absent. Stellaria umbellata Stellaria umbellata is a species of flowering plant in the pink family known by the common names umbrella starwort and umbellate starwort. It is native to western North America from Alaska and northwestern Canada to the southwestern United States, as well as parts of Asia, including Siberia. It grows in subalpine and alpine
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
