What is Blood Brain Barrier

Chapter 2
Examining Biological Foundations of Human Behavior
Blood brain barrier is a protective element with semipermeable architecture formed by extracellular fluid that separates the circulating blood from the brain and extracellular fluid in the central nervous system. Blood brain barrier system allows passage of small molecules including gases such as oxygen and carbon dioxide by passive diffusion; as well also promote the selective transportation of essential nutrients or molecules such as, water, glucose and amino acids, which cannot diffuse due to absence of required polarity.

Abstract
Neuroanatomy is a specific branch within neuroscience that deals with brain anatomy. Its broad area includes the brain structure, organization, and localization/networks of the nervous system. It also helps in understanding the sensorimotor systems, along with associated function like learning, behavior, vision, attention, language, and so on. In the present chapter, the author comprehensively discussed the brain basic morphology, architecture, and also some functional aspects of the brain. At the end of this chapter, the author included the tool and techniques used in the study of brain anatomy so that student can learn and understand the topic clearly.
