Suaeda californica between the leaves, all along the stems. Each cluster has 1 to 5 flowers and is accompanied by a leaflike bract. The calyx is a cone of fleshy, rounded sepals, and there are no petals. The fruit is an utricle that grows within the calyx. This rare plant, "Suaeda californica", grows in a restricted area within the intertidal zone of salt marshes. It is threatened by anything that alters the hydrology of the area, such as changes in sedimentation, including dredging, erosion, and recreation. It requires a porous substrate high in nitrogen, which may come from decaying plant matter and
Calyx of Held nervous system has allowed for direct research within a mammalian model and the large size increases the ease of electrophysiological recording. For these reasons it has been popular in understanding transmitter release. Specifically, the calyx of Held is used because of: Calyx of Held The Calyx of Held is a particularly large synapse in the mammalian auditory central nervous system, so named by Hans Held in his 1893 article "Die centrale Gehörleitung" because of its resemblance to the calyx of a flower. Globular bushy cells in the anteroventral cochlear nucleus (AVCN) send axons to the contralateral medial nucleus of the
