title: The development and maintenance of smooth muscle in control and aneurogenic amphibians (Ambystoma).
abstract: Ultrastructural investigations showed that development and maintenance of smooth muscle was similar in control and aneurogenic amphibian larvae. This applies to both multi-unit and unitary smooth muscles. The gut musculature displayed a regional variation in smooth muscle morphology and a variety of intermuscular appositions even under conditions of nervelessness.
