The diencephalon, or interbrain, is located between the cerebral hemispheres and the brain stem. One can see it by cutting into the central section of the brain. The diencephalon includes the thalamus and the hypothalamus. (Fig. 6-10.) The two parts of the thalamus form the lateral walls of the third ventricle (see Figs.
What is a (CVV) Credit Card Code? For Visa, MasterCard, and Discover cards, the card code is the last 3 digit number located on the back of your card on or above your signature line. For an American Express card, it is the 4 digits on the FRONT above the end of your card number. To help reduce fraud in the card-not-present environment, credit card companies have introduced a card code program.
The CVN code is a special 3-4 digit code used as a security measure for all Internet transactions. It is called CVV2 (Credit card Verification Value) for Visa cards and CVC2 (Credit card Verification Code) for MasterCard. Since the CVN is listed on your credit card, but is not stored anywhere, the only way to know the correct number for your credit card is to physically have possession of the card itself. Because of this, it is a security enhancement against misuse of credit cards. All VISA, MasterCard and American Express cards newer than 5 years have a CVN. Note: The CVN code is printed on your card; it is not raised from the surface of the card like your credit card's account number.
