Structure of the shoot axis Hypocotyl: refers to the section between roots and cotyledons Epicotyl: section between cotyledons and the foliage that follows Nodus (lat. = Knot): area on the branch axis extending from the leaf Tissue of the stem axis Tissue: Epidermis is the terminal tissue of the stem axis; Strengthening tissue: divides into kollenchyma and sclerenchyma; the kollenchyma consists of living, chloroplast-rich cells, the cell wall is thickened; The sclerenchyma, on the other hand, is dead tissue, with cell walls thickened as well. In addition, lignin is incorporated, which makes the cell woody (lignification); Kollenchym and sclerenchyma have a stabilizing function for the shoot axis. Storage tissue: consists of parenchyma and is used to store nutrients. Conductive tissue: the leading bundle comprises the conductive tissues xylem and phloem; Xylem provides for the transport of water and inorganic salts through the plant; Phloem transports organic substances such as sugars and amino acids
Excitatory transmission between neurons If an action potential reaches a synaptic end point, the calcium channels open as a result of the voltage change, and Ca + ions enter the synaptic end point. As a result, the neurotransmitter-filled vesicles are pushed toward the synaptic cleft.

Definition, function and effect Endorphins are a group of opiods that reduce the sensation of pain in humans. The term "endorphin" derives from that of the "endogenous morphine" (endogenous = coming from within), and indicates the fact that the human organism synthesizes these opioid peptides themselves.
