Please elaborate on your questions. I do not understand what you are trying to ask
No muscle allows us to feel emotions. The brain allows us to feel emotions by releasing certain hormones. The brain is an organ, not a muscle. The effects of these emotional feelings can affect the behaviour of the heart (which is a muscular organ, NOT a muscle). For example if you are in love, the heart will beat faster. This is where the misconception that the heart causes feelings of love comes from. The feelings of love, and other emotions, actually come from the brain.
