Though most manufacturers have stayed true to the dual-clutch pattern (two gear splines and two clutches), BMW chose a seven-speed single-clutch version for its mid-2000s M5 super-sedan, while supercar-maker Lamborghini also went with the single-clutch gearbox for its Aventador.
Definition. Meckelâs diverticulum is the most common problem that occurs in the digestive system. This condition happens when a pouch of tissue forms on the wall of the lower part of your small intestine (also known as your bowel).
What are diverticula? A gut diverticulum (singular) is an outpouching of the wall of the gut to form a sac. Diverticula (plural) may occur at any level from esophagus to colon. A true diverticulum includes all three layers of the gut; the lining mucosa, the muscularis, and the outer serosa. False diverticula are missing the muscularis and are therefore very thin walled. Colonic diverticula are typically false.
