The causes for most disorders are not fully understood—at least not for all patients—and likely involve a combination of nature (genetic mutations that become risk factors) and nurture (emotional trauma, stress, hazardous chemical exposure). Because the causes have yet to be fully determined, treatment options are often lacking and only address symptoms.</p>

Summarizing Nervous System Disorders

Biology studies life and living organisms. Biology can be divided into different sections that cover the morphology, physiology, anatomy, behavior, and so on of living organisms.

Biology

Discover the structure and function of neurons and glial cells, how nerve impulses are transmitted within a neuron, and the basics of synaptic transmission and plasticity in the nervous system.
