Answer:
he Taeniae coil
Explanation:
The mesocolic,free and omental taeniae are collectively known as TAENIAE.
They are the 3 ribbon of smooth muscle of the ascending,transverse, descending and the sigmoid colon. Anatomically their longitudinal contractions give the natural bulges(HAUSTRAL) in the colon.
The Haustral helps in translocation of chyme to the next haustral, and aiding the mixing of chyme for water absorption in the colon,
The coil of these smooth muscles is under the parasympathetic nervous system through Sacral nerve (of the spinal cord) innervation.
