Lepuropetalon and usually face upward. They are large compared to the rest of the plant, 2 to 3mm in diameter with male and female parts both present and functional. The calyx consists of five broad, often unequal sepals that are joined in the lower part to form a floral cup that encloses the lower half of the ovary and is thickened along its fissures to form five ribs. The sepals persist beyond the maturity of the fruit. The petals are scale-like, white and barely visible, on the rim of the floral cup between the sepals, or sometimes absent. They die but
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
