Brain's Blood Supply
|
Brain's Blood Supply is a introductory lesson from A & P Technologist.
To carry out its vital functions, the human brain consumes a great deal of energy in the form of glucose. To supply glucose for energy, the brain receives up to one-quarter of the total cardiac output of blood through two pairs of arteries—the
internal carotids and the vertebrals. X-rays can be used to study these arteries in a living person, often to diagnose abnormalities in blood flow to the brain.

This exercise makes use of the applet version of ImageJ. This version should shortly be running in a separate "ImageJ" window. The download will take a few seconds with an Ethernet connection or about two minutes using a 28.8 modem. Quit ImageJ by clicking on the "ImageJ" window's close button. When you go to the Windows version of one of the exercises below the ImageJ application will remain running in the background.
(NOTE: ImageJ opens up without any problems using either Netscape of Internet Explorer on Windows. Internet Explorer 4.5 and above works fine on the Macintosh, but there is no Netscape support at this time on the Macintosh. . If you wish to download a version of ImageJ to your computer's hard drive so you can evaluate your own images a download can be obtained at the following site.
Problems and Comments on ImageJ's performance. An Adobe file that you might want to look at and/or print out.
In the exercises categories that are described below you will have three windows open at a time (the WEB page, ImageJ and at least one image) so you may want to go to your control panel on your computer and change the monitor size so that you can readily move between the different windows.
