Cerebrum is in the most anterior part of our brain, fronting of the skull. It functions in sensory and neural processes. Cerebellum is found at the back of the skull. It functions in coordination, balance and muscular activity. Medulla oblongata connects from the spinal cord which controls heart and lungs. Pons is part of the brainstem which controls breathing and communication.
It happens because of Point mutation
Explanation:
A point mutation can be understood as when one nucleotide is added, deleted or changed. Through change in DNA structure a gene can be altered and it is called mutation. Point mutation’s other term is insertion as well as deletion. It mostly involves in substitution.
Rarely, Point mutation is responsible for huge change. Basically, two types of point mutation happen. They are transition or transversion mutations.
Baroreceptors. These are found in the carotids and aortic arch. They respond to pressure exerted on the vessels.
