Explanation A spinal nerve consists of 31 pairs of nerves that originate from the spinal cord. There are four regions of the spinal cord that consists of the nerve fibers as follows:- Cervical region: The cervical spine or the neck is a delicate bone found in the spinal cord that transfers signals from the brain to other parts of the body. It consists of 8 pairs of cervical nerves from C1 to C8. Thoracic region: The thoracic is located in the chest area and connected with spinal cord. It consists of 12 (T1 to T12) thoracic nerves that emerge from the lumbar spine. Lumbar region: The lumbar region or lower back of spinal cord is situated between the sacrum and thoracic...

Summary Introduction

Introduction:

The spinal cord is a collection of nerve tissue that arises from the brain stem. It is a site that contains many motor neurons, interneurons, and complex neural circuits. The spinal cord tracts are stimulatory nerve pathways that pass the information through action potentials. It is often called the ‘nuts and bolts’ of the nervous system. It controls and enables the forces on muscles and its adaptive movements.

"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?
