Streptanthus farnsworthianus at intervals along the upper stem with one or two leaflike purple bracts at the base of the raceme. Each flower has an urn-shaped calyx of purple sepals up to a centimeter long. Curling purple-veined white petals emerge from the tip of the calyx. The fruit is a straight or curving silique up to 12 centimeters long. The plant was named for Evalyn Lucille Klein Farnsworth, a foothills cattle rancher and plant collector who first discovered it growing on her land. Streptanthus farnsworthianus Streptanthus farnsworthianus is an uncommon species of flowering plant in the mustard family known by the common
Calyx of Held The first is that in the second week of development, myelination of the VCN axons in the MNTB increases. This prominent growth in myelin corresponds to the chronological development of the signaling circuit and adaptation of the calyx. The second ultrastructural change involves the principal neurons of the MNTBs, whose cell bodies and nuclei increase in surface area due to enlargement. This is a direct result of individual, larger postsynaptic densities breaking up into smaller, multiple densities. Potassium channels are vital in conducting the presynaptic action potential. The calyx contains several types of potassium channels, each differing in location and
