The cerebellum, located at the back of the brain, integrates sensory input and fine-tunes motor activity, posture, and equilibrium. The cerebrum handles conscious thought and voluntary actions, the thalamus relays sensory information, the medulla controls vital autonomic functions like breathing and heart rate.

Explanation:
Insulin is a peptide hormone produced by the beta cells of the Islets of Langerhans in the pancreas. It is initially synthesized as a single, inactive polypeptide precursor called proinsulin. During processing, a connecting peptide (C-peptide) is removed, leaving two polypeptide chains: the A chain (21 amino acids) and the B chain (30 amino acids). These two chains are held together by two interchain disulfide bridges (covalent bonds between sulfur atoms of cysteine residues), and there is also one intrachain disulfide bridge within the A chain.
