The peripheral nervous system is comprised of the somatic and autonomic nervous systems. The somatic nervous system transmits sensory and motor signals to and from the central nervous system. The autonomic nervous system controls the function of our organs and glands, and can be divided into the sympathetic and parasympathetic divisions. Sympathetic activation prepares us for fight or flight, while parasympathetic activation is associated with normal functioning under relaxed conditions. The endocrine system consists of a series of glands that produce chemical substances known as hormones, which produce widespread effects on the body. Got all that?
The endocrine system is a system of ductless glands that secrete hormonesóchemical messengers that are carried for long distances. The endocrine system is a system of ductless glands that secretes hormones directly into the circulatory system to be carried long distances to other target organs regulating key body and organ functions. For example, the pineal gland, located at the base of the brain, secretes the hormone melatonin, responsible for regulating sleep patterns. Endocrine glands are typically well vascularized and the cells comprising the tissue are typically rich in intracellular vacuoles or granules that store hormones prior to release. Endocrine signaling is typically slow to initiate but is prolonged in response; this provides a counterpoint to the more rapid and short-lived nervous system signals. The endocrine system is in contrast to the exocrine system, which features ducted glands that secrete substances onto an epithelial surface; for example, a sweat gland.

Now that we have considered how individual neurons operate and the roles of the different brain areas, it is time to ask how the body manages to put it all together. How do the complex activities in the various parts of the brain, the simple all-or-nothing firings of billions of interconnected neurons, and the various chemical systems within the body work together to allow the body to respond to the social environment and engage in everyday behaviours? In this section we will see that the complexities of human behaviour are accomplished through the joint actions of electrical and chemical processes in the nervous system and the endocrine system. The nervous system see Figure 4. The CNS interprets information coming in from the senses, formulates an appropriate reaction, and sends responses to the appropriate system to respond accordingly. Everything that we see, hear, smell, touch, and taste is conveyed to us from our sensory organs as neural impulses, and each of the commands that the brain sends to the body, both consciously and unconsciously, travels through this system as well.
The hypothalamus plays a significant role in the endocrine system. Hypothalamic Disease A disease or disorder of the hypothalamus is known as a hypothalamic disease. A physical injury to the head that impacts the hypothalamus is one of the most common causes of hypothalamic disease. Hypothalamic diseases can include appetite and sleep disorders, but because the hypothalamus affects so many different parts of the endocrine system , it can be hard to pinpoint whether the root cause of the disorder is actually related to another gland. These are known as hypothalamic-pituitary disorders. However, there are hormone tests that help shed light on which part of the body is the root cause.
The endocrine system is an organ system which consists of various glands around the body examples of which are the Hypothalamus, Pituitary gland, Parathyroid gland, Thyroid gland, Adrenal glands, Pancreas, Ovaries in females and Testies in the male body. These glands secrete hormones directly into the bloodstream. In our bodies the nervous system is made up of two parts: the central nervous system and the peripheral nervous system. The central nervous system consists of the brain, spinal cord, and the retina. The peripheral nervous system consists of sensory neurons, clusters of neurons which are called ganglia, and nerves which connect them to each other and to the central nervous system. All of these regions are all interconnected by means of complex neural pathways. The hypothalamus is a gland which is found in the brain and it links the endocrine system and the nervous system together.
