Circular Muscular Layer of Colon (Transverse Colon: Anterior)
Stratum musculare circulare coli
Read moreStructure/Morphology
The muscular layer of the colon, like the small intestine, consists of an inner circular layer and an outer longitudinal layer of smooth muscle fibers.

Key Features/Anatomical Relations
The circular layer of smooth muscle fibers surrounds the mucosal and submucosal layers of the colon.
Function
The coordinated contractions of the longitudinal and circular muscular layer of the colon are responsible for producing peristaltic contractions of the gut, thus propelling the ingested substance through the lumen of the gut.

Sigmoid
The sigmoid-like function due to electrical resonance is as follows:(6)gx=Vβx−1βxwhere β is the electrical resonance amplification gain, which is a function of the circuit electrical damping condition, the MEMS deflection, and the difference between the input voltage frequency and the circuit resonance frequency.
