muscularis mus·cu·lar·is (mŭs'kyə-lâr'ĭs)
The muscular coat of a hollow organ or tubular structure.
These cells are most abundant near the muscularis mucos and in the submucosa.
My diagnosis was paresis of the muscularis of the intestine.
The muscularis mucos is hypertrophied, and is evident to the naked eye as a grayish band.
Atony of the muscularis of the intestine is admittedly the direct cause, in most instances, of constipation.
The tumor usually begins in the mucous membrane and rapidly extends through the muscularis mucos into the submucous coat.
