Amygdala, one of the four basal ganglia in the cerebral hemisphere is part of the limbic system which consisting of an almond like -shaped mass of gray matter is located deep in the brain's medial temporal lobe.
The amygdala is involved in the autonomic responses related with fear and hormonal secretions, emotional memory and instinctual behaviour.
For example if we are exposed to a fearful situation, information about that fearful situation is sent to the amygdala immediately, which sends signals to areas of the brain called hypothalamus which then triggers a "fight-or-flight" response in us .
Your pulse can show you so much things! You can try to detect murmurs, or irregular heart beats, or you can see if your heart rate is in a healthy zone.
Not just in the term "cystectomy," but with any medical term that ends with "-ectomy," refers to the removal of an object from one's body (often surgically). I hope this helped !
