The structural organization of autonomic nervous system or ANS is different from somatic nervous system or SNS.
In the ANS, the motor neurons of the central nervous system do not directly control visceral effectors. They synapse with visceral motor neurons or preganglionic neurons in ganglia, and the ganglionic neurons control the visceral effectors.
cells become specialized in structure and function, and these are organized into tissues and organs. Activities of a cell depend on the genes it expresses and the proteins it produces. Specific activators turn on the collection of genes whose products are needed in the cell. Materials placed into the cell by the mother set up a sequential program of gene regulation that's carried out as cells divide.Explain what occurs in morphogenesis:The physical processes that give an organism its shape. Literally meaning, "creation
Answer:
The type of protein that binds a ligand on the cell surface or within cells are transmembrane receptors. These proteins have 3 domains: an extracellular part that does the binding, a hydrophobic domain that extends through the membrane, and an intracellular region that transmits the signal. The most common membrane-anchored receptors are: G protein-coupled receptors, receptor tyrosine kinases, and ligand-gated ion channels.
