PATHOLOGY

Detailed explanation-1: -For example, vasopressin and oxytocin, two peptide hormones that are released into the circulation from the posterior pituitary, also function as neurotransmitters at a number of central synapses. A number of other peptides also serve as both hormones and neurotransmitters.

Detailed explanation-2: -Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body. They enable the brain to provide a variety of functions, through the process of chemical synaptic transmission. These endogenous chemicals are integral in shaping everyday life and functions.[1]

Detailed explanation-3: -Hormones and neurotransmitters are different chemical messengers, the former produced by the endocrine glands and the latter by the nervous system.
