Answer:
I would be the extension of the trunk
Explanation:
The erector spinae muscle extends the vertebreal column. [1] It is formed of 3 muscles and its fibers run more or less vertically throughout the lumbar, thoracic and cervical regions. It lies in the groove to the side of the vertebral column. In cervical region it is covered by nuchal ligament and in thoracic and lumber region by thoracolumbar fascia.
I agree with the other person - emotion is the part of consciousness that involves feeling or sensibility.
Feelings and emotions are the same thing - those two words are synonyms, which means their meaning is identical. So when you feel something, that particular something is called emotion or feeling, and is related to sensibility.
