Is Breathing voluntary or involuntary?

Breathing is a complex motor task that needs to be coordinated at all times while we eat, speak, exercise and even during sleep. The breathing muscles are controlled automatically from the brainstem during normal breathing but can also be controlled voluntarily from the motor cortex.

Do emotions come from the heart or brain?

Psychologists once maintained that emotions were purely mental expressions generated by the brain alone. We now know that this is not true — emotions have as much to do with the heart and body as they do with the brain. Of the bodily organs, the heart plays a particularly important role in our emotional experience.

Does the heart have memory?

The various ontogenetic passages form the evolutive basis of the final configuration of the heart. Each key step can be recognized in the final features, as the heart maintains a kind of “memory” of these passages. We can identify the major lines of development of the heart and trace these lines up to the mature organ.

Why does the heart beat involuntary?

Each beat of your pulse is caused by the contraction of the heart muscles. Unlike the muscles in your arms, legs, and other parts of the body, the heart muscles contract involuntarily, meaning that there is no way to consciously control when the heart beats.
