Vedclass · Answer

(C) Sphincters are specialized circular muscles that control the passage of substances through body openings.$(i)$ Sphincters are mesodermal in origin,as they are composed of muscle tissue.$(ii)$ They contain stretch receptors that help in regulating their tone and contraction based on the presence of contents.$(iii)$ Rhythmic contractions are characteristic of cardiac muscle or peristaltic movements,not typical sphincters,which generally maintain a tonic state of contraction.$(iv)$ Sphincters do not fatigue during the life of the animal because they are designed to maintain a constant state of contraction to prevent leakage.Therefore,the characteristics $(i), (ii),$ and $(iv)$ are associated with sphincters.

Contractile tissues have the following features:
$(i)$ Mesodermal in origin
$(ii)$ They contain stretch receptors
$(iii)$ Rhythmic contractions are seen in them
