The plexuses that are formed by the ventral rami and also explain about the regions of the body they serve. Introduction: The spinal nerves are the mixed nerves that arise from the spinal cord. They exist as 31 pairs. They perform sensory functions (bring information back from the area they serve), motor functions (carry information to the effector's muscles), and autonomic functions (proper functioning of the internal organs). The spinal nerves branch into dorsal ramus, ventral ramus, meninges, and rami communicants outside the vertebral column. The ventral ramus consists of nerves that serve an anterior portion of the trunk and the upper and lower limbs as well. The nerve plexuses are the braid-like network of blood vessels and the nerves.

You have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.
