| The arteries were most susceptible, with bruising of the intima and adventitia and separation of the media from the vessel walls. |
| Dissection refers to a tear or defect in the intima of the aorta which allows blood to enter the media, separating it into two layers. |
| These are superficial lacerations of the intima that do not involve the media or adventitia. |
| By 20 years of age, all humans, regardless of race or gender, develop focal thickening of the intima of medium-sized arteries. |
| With still greater increases in caliber, a distinct intima, media, and adventitia become recognizable. |
| Alternatively, thickness of the carotid intima and media may be measured by using ultrasound. |
