BloodBrain Barrier Diagram Biology Diagrams The blood-brain barrier (BBB), first described by Paul Ehlrich (1885), is a highly selective semi-permeable membrane between the blood and brain interstitium. Anatomy, Head and Neck: Blood Brain Barrier. Dotiwala AK, McCausland C, Samra NS. StatPearls. 2025 Jan. Anatomy, Head and Neck, Larynx Recurrent Laryngeal Nerve. [StatPearls. 2025] Overview of Blood-Brain Barrier: Anatomy. The blood-brain barrier (BBB) is a dynamic interface between the peripheral circulation and the central nervous system (CNS). The basic element of the BBB, the neurovascular unit, is a complex structure composed of capillary endothelial cells (ECs), astrocytes, pericytes, and neurons. Location of barrier sites in the CNS. Blood enters the brain via surface arteries (red arrow, top). Barriers between blood and neural tissue are present at three main sites: (1) the brain endothelium forming the blood-brain barrier (BBB), (2) the choroid plexus epithelium which secretes cerebrospinal fluid (CSF) and (3) the arachnoid epithelium forming the middle layer of the meninges.
The blood-brain barrier (BBB) is a semipermeable and extremely selective system in the central nervous system of most vertebrates, that separates blood from the brain's extracellular fluid. It plays a vital role in regulating the transport of necessary materials for brain function, furthermore, protecting it from foreign substances in the blood The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs). Blood-Brain Barrier / anatomy & histology* Blood-Brain Barrier / metabolism* Blood-Brain Barrier Your blood-brain barrier (BBB) is a filtering layer of cells surrounding blood vessels in most areas of your brain. It's a critical line of defense, keeping most harmful things out and most helpful things in. But it isn't perfect. Many conditions can affect it, and healthcare providers have to consider the BBB when trying to treat all

Blood-brain barrier (BBB) is a semi-permeable barrier encompassing microvasculature of central nervous system (CNS). In the capillaries, the wedged endothelial cells line in the interior vessels
Anatomy and Function of the Blood-Brain Barrier. The blood-brain barrier (BBB) is a complex and highly selective interface between the circulatory system and the central nervous system (CNS). Its primary role is to protect the brain by regulating the passage of substances and maintaining the optimal environment for proper brain functioning
