Rhythmic segmentation of small intestine is characterized by the following except:
A)It is due to local axon reflex.
B)It is myogenic.
C)Its frequency is determined by BER.
D)Its main function is to mix chyme with the digestive juice.

Question

Quizplus · Accepted Answer

Rhythmic segmentation of the small intestine is primarily a myogenic process (B), influenced by the basic electrical rhythm (BER) (C), and its main function is indeed to mix chyme with digestive juices (D). The statement that it is due to a local axon reflex (A) is incorrect because the process is not primarily driven by neural mechanisms but by the muscles in the intestine itself.
