The gastrointestinal (GI) tract components, in which muscularis is composed of skeletal muscles. Also, discuss whether skeletal muscle controls these components is involuntary or voluntary.
Introduction:
The GI tract's wall has tissues that are arranged in four layers, namely mucosa, muscularis, submucosa, and serosa or adventitia. The tissue muscularis is composed of skeletal muscles and smooth muscles.
