Summary Introduction

To review:

Whether short preganglionic fibers, terminal ganglia, collateral ganglia, origin from the thoracolumbar region of the spinal cord, and innervates adrenal medulla are the characteristic feature of sympathetic or parasympathetic nervous system.

Introduction:

The ANS (autonomic nervous system) is comprised of two units that are the parasympathetic nervous system and SNS (sympathetic nervous system). ANS is involuntary control of the body tissues. The spinal cord comprises 31 pairs of segments and is important because the sympathetic and parasympathetic nerves arise from them.

"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.  1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site  4. BMP4 on outside-> nodal  Are all of these occuring opposite to AVE?
