Preganglionic axons synapse at the sympathetic chain ganglia with a postganglionic neuron. The postganglionic neuron then leaves the sympathetic chain ganglia through a gray ramus communicans (unmyelinated axons) and reenters the spinal nerve and travels to the skin and blood vessels throughout the body.
Answer:
<h2>nuclear envelope is made is known as nuclear membrane it is covered by two lipids by layer</h2><h3><em>So</em><em> </em><em>answe</em><em>r</em><em> </em><em>is</em><em> </em><em>2</em></h3>
In moving from the outside environment to the inside of a bacterium, the first layer encountered would be Glycocalyx.
The cell coat or outermost layer of bacterial cells is called the glycocalyx. Glycoproteins, glycolipids, and proteoglycans make up its composition.
It is a network of lipids and membrane proteins connected by polysaccharide chains. On the lumen side, it encircles the vascular endothelial cells.
Various bacteria have varied glycocalyx layers with different compositions and densities. It serves as a protective layer and participates in cell interaction, signalling, and identification.
