Explanation Pictorial representation: The spinal cord consists of two types of nervous tissue namely gray matter and white matter. These nervous tissues are composed of organized cells that involve the body movements and send the signals to different parts of the body. Gray matter: It is a central core of the spinal cord, and it looks like a butterfly or ‘H’ shaped in the cross-section anatomy. It is pinkish gray in color and composed of little amount of myelin. It contains dendrites, cell bodies, and axon terminals of the neuron. It involves in the synaptic contact between the neurons, and it is considered as the site of all neural integration of the spinal cord. The central of the spinal cord consists of two posterior or dorsal horns and two thicker anterior or ventral horns. The two posterior or dorsal horns are located at the posterolateral surfaces of the cord...

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. It is often called as ‘nuts and bolts’ of the nervous system. It controls and enables the forces on muscles and its adaptive movements. The nervous tissue of the spinal cord is composed of organized cells that involve the body movements and send the signals to different parts of the body.

We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen. I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates. List 3 possible pathogens or diseases that you might want to do for your group project.
