system is a receptor‚ this detects changes. The integrator‚ which determines response. Lastly the effector directs some sort of response.The hypothalamus is a section of the brain responsible for the production of many of the body’s essential hormones for example chemical substances that help control different cells and organs. The hormones from the hypothalamus govern physiologic functions such as temperature regulation‚ thirst‚ sleep‚ mood‚ and the release of other hormones within the body. - Thermoregulation

The brain of an average human being contains 100 billion nerve cells or neurons. Billions more are found in other parts of the nervous system. Neurons come in all different sizes and shapes‚ but they all seem to be specialized to receive and transmit information. Neurons are made of neurons which contains chromosomes and genes‚ a cytoplasm which keeps the cells alive and a cell membrane that encloses the whole cell. Neurons are different from other cells because they have small fibers that branch

These structures include the amygdala‚ mammillary body‚ hippocampus‚ fornix‚ cortex of the cingulate gyrus‚ septum‚ olfactory bulb‚ and hypothalamus. Papez believed that emotional states are expressed through actions of limbic structures in the hypothalamus and that they are experienced through actions of limbic structures in the cortex.
