C) multi-unit smooth muscles
D) visceral smooth muscles

Quizplus · Accepted Answer

Visceral smooth muscles are arranged in sheets or layers and are electrically connected by gap junctions and mechanically connected by dense bodies. Multi-unit smooth muscles also have adjacent cells connected by gap junctions, but they are not arranged in sheets or layers, and are typically found in structures like blood vessels or the iris of the eye. Skeletal muscles are made up of individual muscle fibers and are not electrically or mechanically connected to adjacent fibers. Cardiac muscles are also electrically connected by gap junctions, but they are not mechanically connected by dense bodies and have a characteristic branching pattern.
