The way in which the neurons of the vertebrates avoid unproductive synapses with themselves effectively though it seems almost inevitable to occur. Concept introduction: Neurons are the structural and functional unit of the nervous system. The neurons develop from the ectoderm of the gastrula. Neurons are made of dendrites, axons and a cell body. The dendrites of one neuron make connection with axon of another neuron or dendrite of another neuron or two axons of two neurons makes connection, called as synapse. The dendrites of the neurons are highly branched structures which has the high possibility of making self synapses which is unproductive but that is avoided during development itself.

(This is a 2-part work, Part 1 is done, only Part 2 is to be worked on at the bottom)Part 1 (Done): Describe the levels of structural hierarchy for the human body, starting with the organismal level and ending with the chemical level. In addition, you should make sure you link each level to the previous level, emphasizing the structural relationships. The human body is organized into a structural hierarchy that progresses from the macroscopic organismal level down to the microscopic chemical level. Each level builds upon the previous one, creating increasingly complex structures. Below is the hierarchy, from largest to smallest, with explanations linking each level to its predecessor: 1. Organismal Level The entire living human body.Relationship: All lower levels work together to sustain life at this highest level. 2. Organ System Level Groups of organs working together to perform major functions.Examples: circulatory, nervous, digestive systems.Relationship: The organismal…
