WebThe detectors for regulating body temperature are temperature-sensitive neurons in the anterior hypothalamus. The hypothalamus is an area of the brain which controls many different homeostatic mechanisms. Once this sensory input reaches the brain, it is relayed through a connector neuron in the brain and sent to an effector via a motor neuron. WebChanges in blood pressure are sensed by specific mechanosensory proteins, called baroreceptors, particularly located in the outer layer of the carotid sinus and the inner curvature of the aortic arch. The signal is propagated along the afferent nerves to the central nervous system and serves as negative feedback of the heart rate.
