Hindbrain
Outline
The introduction briefly talks about the hindbrain, its location, structure and highlights its main functions. It also talks about how the hindbrain is divided.
The next topic is about Structure and Function. It first starts with the functions of the hind brain and then mentions each and every function of the brainstem, that it, the medulla, pons and the cerebellum. It also mentions the functions of the cranial nerves.
The next section is on Injury and Disorder. Here it is mentioned, as a list, the various disabilities that the brainstem could have. These include the consequences when a stroke occurs in that region.
The final section is on the recent research that has been done in …show more content…
Structure and Function
The functions of the hindbrain cover the primitive instincts and vital bodily functions such as heartbeat, breathing and digestion. The hindbrain also controls involuntary digestive and respiratory reflexes such as vomiting, coughing, swallowing and sneezing to expel dust and other foreign particles from the body. (What are the functions of the hindbrain?, n.d.)
Each of the three major regions of the hindbrain have particular functions:
The Medulla is placed at the base of the skull just above the spinal cord and below the cerebellum. It is found in the myelencephalon region of the hindbrain. The rhomberes Rh8-Rh4 form the myelencephalon. It carries information between the spinal cord and the higher parts of the brain. It also controls autonomic functions such as heartbeat and respiration. It controls the contraction and expansion of the diaphragm and lungs and the dilation and contraction of the blood vessels by working with the hypothalamus to ensure homeostasis is maintained. It also helps in maintaining the upright position of our body. All these functions of medulla is possible with the help of cranial nerves. The medulla houses a portion of the reticular formation. Reticular formation is a set of interconnected nuclei that are located throughout the brainstem. The respiratory centre in …show more content…
With obesity being a cultural syndrome in the US, there is a necessity to find solutions for it. Previous work has emphasized the importance of neuropeptides (protein neurotransmitters) in controlling obesity triggering factors such as ingestion and energy expenditure. The orexins (orexin A and orexin B) are a family of neuropeptides important in promoting physical activity, and have also recently been shown to increase energy expenditure through effects on thermogenesis. The research looks at the hindbrain signalling orexin A helps in controlling energy expenditure via thermogenesis. (Lee,
