Document Summary
Memorization, attention, decision making lobe (higher level thinking and functioning) Vascularized by (blood vessels supply it: lateral surface middle cerebral artery, medial surface anterior cerebral artery. Interior surface middle and anterior cerebral arteries. Medial (interior) surface middle and posterior cerebral arteries. If you have a stroke damaging mca, it causes more damage bc mca plays a major role in all lobe functioning. Capillaries: smallest blood vessels: no neuron is more than 50 micrometers (. 05 mm) from a capillary means all close to blood, anything you do is run by neurons (play an important role in survival) Blood brain barrier: stops any random molecules that made its way into your blood and keeps away from neurons (ie toxins or parasites: extra protection for brain tissues. Inside layer of cells is called endothelial cells (usually have a space between them) In the brain, there are tight junctions more close together so no random molecules make its way into the blood.
