What are the different parts of the hypothalamus?
Hypothalamus has three parts: front, tuberal and rear. Each part plays its own role in the overall functions and duties of the endocrine system. General responsibilities include connection to the endocrine system and the nervous system. Most importantly, this small part of the brain maintains homeostasis that maintains suitable conditions that the body must function properly.
Although hypothalamus is a small organ in the brain, it has large tasks. It is shaped as a cone and is located above the brain under the thalamus. This part stretches down until it has encountered an infundibular stem, a tube that is associated with pituitary. In general, this body has multiple functions that are divided into each of the three parts. Olfstimulation in the turntable often affects endocrine hormones. Glucorticoids and steroids affect reactions such as appetite or thirst. The exposure to daylight is an obvious signal; It helps to regulate the sleep cycle and awakening.
The front area of the hypothalamus is located at the front and is responsible for several functions. It isThe key part of the thermoregulation, which is the control of the body temperature. Thermoregulation is controlled by sweat and trap. The front area is also regulated by sleep and circadian cycles.
In the middle of the hypothalamus, a tuberal area is found. This part is in charge of thirsty and hunger. The tuberal area also controls blood pressure and heart rate. This area is regulated by the regulation of growth and dopamine production.
On the back of the hypothalamus is the back area. Increasing blood pressure, shaking and dilation of pupils is controlled by this area. Memory functions are also affected by this area.
As a whole hypothalamus, it controls many important body functions. Neurohormones are controlled and released in the brain. Through these hormones, pituitary activity as well as metabolic processes of the entire autonomic nervous system are controlled.
In addition to hormones and control of metabolic aspects controls hypothalamus soé hormones that affect the endocrine system. Endocrine hormones are sent to the pituitary gland and play a role in certain behavior that are based on emotions such as anger, anxiety or fear and sexual activity.
