Silene campanulata the lower ones lance-shaped to rounded, and the upper ones linear or oval. Nodding flowers occur in a terminal cyme at the top of the stem, as well as in some of the leaf axils. Each has a hairy, often glandular calyx of fused sepals. This bell-shaped green or purplish calyx is open at the top, revealing five white, greenish, or pale pink petals. The petals have multilobed or fringed tips. The stamens and three long styles protrude from the flower's center.

Calyx of Held of Held has been used to understand a variety of mechanisms related to development of, and vesicle release of the synapse. The calyx of Held is a part of the auditory system, connecting the globular bushy cells (GBCs) of the anteroventral cochlear nucleus to the principal neurons of the medial nucleus of the trapezoid body (MNTB). As a synapse, the function of the calyx of Held is to transmit the signal from the GBCs to the principal neurons. The principal neurons of the MNTB are glycinergic, thus hyperpolarizing the superior olivary complex (SOC) nuclei in nearby cells and producing tonotopic
