Elastic lamina is predominantly found in arteries. There are two types of elastic lamina in these vessels: the internal elastic lamina (IEL) and the external elastic lamina (EEL). The internal elastic lamina is located between the tunica intima and the tunica media, while the external elastic lamina is situated between the tunica media and the tunica adventitia. These layers are especially prominent in large arteries such as the aorta and its major branches, which undergo significant pressure fluctuations.
