Answer: (C)

Pars nervosa is also called as posterior pituitary. Coherin is a hormone-like factor isolated from bovine posterior pituitary. It is involved in the mechanism of myenteric neuronal activation. This factor has potent activity in the regulation of mammalian gastrointestinal motor function. This substance alters the frequency, amplitude, rhythm, and duration of peristaltic contraction.
