Sessility (botany) subsessile, which is not completely sessile. Sessility (botany) In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts that have no stalk. Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles. The term sessility is also used in mycology to describe a fungal fruit body that is attached to or seated directly on the surface of the substrate, lacking a supporting stipe or pedicel. Other examples of sessile flowers include Achyranthus, Saffron, etc. Plant
Calyx of Held inhibitory effects. As a result of its role in stimulating the principal neurons, the primary function of the calyx of Held is to allow differentiation between temporal activation of the cochlear hair cells that are important in sound localization (interaural level detection). Interaural level detection is possible through the calyx system due to the large relative size of the GBCs, the calyx of Held, and the principal neurons. The neurons in the Lateral Superior Olive are especially important in discerning these interaural level changes. The large diameter size of the bushy cell axons allows the inhibitory signal produced by the
