The forebrain is the main thinking part of the brain. It has regions which receive sensory impulses from various receptors. The brain has three major parts, namely the fore brain, mid brain and hind brain. Midbrain and Hindbrain control involuntary activities. Cerebellum controls voluntary activities.
Hormones:
Hormones are part of the endocrine system which constitutes a second way of control and coordination in our body. Hormones produced in one part of an organism move to another part to achieve the desired effect.
