Document Summary
Cte chronic traumatic encephalopathy, a form of progressive brain damage that has been linked to repeated concussions. There are approximately 100 billion nerve cells in your brain that perform a variety of tasks to allow you to function as a human being. Humans have thoughts, feelings, and behaviours that are often accompanied by visible signals. All those visible and experiential signs are coordinated by the activity of your brain cells. These cells are neurons, cells in the nervous system that communicate with one another to perform information-processing tasks. Cajal discovered that neurons are complex structures composed of three basic parts: Cell body (soma) is the largest component of the neuron that coordinates the information-processing tasks and keeps the cell alive. Functions such as protein synthesis, energy production, and metabolism take place here. The cell body contains a nucleus, which houses chromosomes that contain our dna, or the genetic blueprint of who we are.
