Nematocysts - The Stinging Cells | Zoology for IAS, IFoS and other ... MECHANISM OF DISCHARGE The discharge of nematocyst thread tube from the cnidocyte takes place due to mechanical or chemical stimuli received by the cnidocil. In a resting stage the capsule wall is not permeable to water and there is very high osmotic pressure since the hypnotoxin inside is hypertonic to external water.

Draw and label the stages of a nematocyst discharge. Cilium Evolution: Identification of a Novel Protein, Nematocilin, in ... The nematocyst is a complex intracellular organelle, which is formed during differentiation of nematocytes. After nematocyst formation is completed, the cell cluster falls apart into single nematocytes, which migrate to the tentacles and are mounted in ectodermal epithelial cells (battery cells). The regulation of cnidocyte discharge - ScienceDirect A cnidocyte's structural complexity is mirrored by its functional complexity. Cnidocyte discharge is, in essence, an explosive event that results in the inverted tubule being extruded through the operculum at the apical end of the cyst with, in the case of penetrant cnidocytes, sufficient force to penetrate the cuticle or skin of prey, over a time period of less than 3 ms (Tardent and Holstein ...

Internal Structure of Hydra (With Diagram) - Biology Discussion Following explanations are offered for discharge of nematocysts: (a) There are two factors responsible for discharge, first the presence of certain liquid-like chemicals in the water, second a mechanical contact of the cnidocil and cnidoblast by food animal or prey, if both chemical and tactile sitmuli are present then the nematocyst is discharged.
