Hey there! Let's solve the problem:
CD4 T cells activate CD8 T cells through an underhanded cycle including an antigen presenting cell (APC), customarily a standard dendritic cell (DC). An APC presents a peptide to a true CD4 T cell through a Class II MHC molecule.
<span>This is turgor pressure. This is the mechanism by which a plant and its cell walls can maintain its rigidity. The movement of water between the cell walls and the inside of the plant allows for pressure to build up due to this diffusion, leading to a stiffness on the part of the plant.</span>
Answer:
The cell bodies of the preganglionic neurons are in the brainstem or spinal cord of the central nervous system (CNS). The cell bodies of the postganglionic neurons are in autonomic ganglia located peripherally. Axon terminal of preganglionic neurons synapse on dendrites and cell bodies of postganglionic neurons.
