Lithophragma heterophyllum Lithophragma heterophyllum Lithophragma heterophyllum is a species of flowering plant in the saxifrage family known by the common name hillside woodland star. It is native to the coastal mountain ranges of California, where it can generally be found in shady habitat. It is a rhizomatous perennial herb growing erect or leaning with a slender naked flowering stem. The leaves are located on the lower part of the stem, each divided into rounded lobes. The stem bears 3 to 12 flowers, each in a cuplike calyx of red or green sepals. The five petals are white, up to 1.2 centimeters long,
Calyx of Held a mature calyx that facilitates the consistent, rapid spread of signals in the MNTB-VCN area. A select few processes occur during early neuronal development in order to ensure proper calyx formation, specifically through the influence of Fibroblastic Growth Factor (FGF), transcription factor Math5, neural cell recognition molecule NB-2, and ephrin (Eph) proteins in cells. Math1/Math5 and FGF are two regulators essential for appropriate growth and development of the cochlear nucleus complex, which comprises both the ventral cochlear nucleus (VCN) and the dorsal cochlear nucleus (DCN). Sufficient FGF levels ensure proper morphology of the cochlear nuclei, while Math5 insures correct size
