Louie, it is great to see your here on the forum again.
Before I respond, I’d like to say that I am forever a work-in-progress. I have no desire to stop increasing my knowledge about the human body and humbly say I don’t know everything. I am knowledgeable in some things but far from an expert.
Louie, please correct me if I am mistaken. Are you referring to the Moro reflex also known at the embrace reflex or the startle reflex?
I’ve included a link so all can know what you are referring to in the case we are on the same page. If I am mistaken, I’d like to be enlightened.
Moro (startle reflex in infants)
Moro Reflex (startle) definition
Louie, if this is what you are referring to, I really don’t see the correlation. Help me out with this please.
N.B. We all know that no muscle group can work in isolation. Agonists, antagonists, stabilizers and neutralizers all work together (among other components to produce movement).
