|
Slow waves originate from:
|
|
enterocytes
|
|
|
postganglionic cells
|
|
|
interstitial cells of Cajal
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Myenteric interstitial cells of Cajal (ICC-MY) serve as pacemaker cells that generate the bioelectrical events known as slow waves. Slow waves conduct to smooth muscle cells and cause phasic contractions.
Detailed explanation-2: -Specialized cells known as interstitial cells of Cajal (ICC) are distributed in specific locations within the tunica muscularis of the gastrointestinal tract and serve as electrical pacemakers, active propagation pathways for slow waves, and mediators of enteric motor neurotransmission.
Detailed explanation-3: -Interstitial cells of Cajal generate electrical slow waves in the murine stomach-PMC.
