The autonomic reflex centers are located in the brainstem and spinal cord. The brainstem houses important autonomic centers such as the medulla oblongata and pons, which regulate functions like heart rate and respiration. The spinal cord contains reflex arcs that control activities like urination and defecation.
Autonomic ganglia contain the cell bodies of motor neurons.
The medulla oblongata is often referred to as the "vital center" because it plays a crucial role in regulating essential autonomic functions necessary for survival, such as heart rate, blood pressure, and respiration. It contains centers that control these functions, ensuring that the body maintains homeostasis. Any significant damage to the medulla can lead to life-threatening conditions, highlighting its importance in sustaining vital bodily processes.
the medulla oblongata
It is the nucleus.It controls all the activities of the cell.
The brainstem, specifically the medulla oblongata, is primarily responsible for regulating respiration. The respiratory control centers in the medulla help coordinate the muscles involved in breathing and adjust the rate and depth of breaths to maintain appropriate levels of oxygen and carbon dioxide in the body. The pons also plays a role in regulating breathing by helping to smooth out the breathing pattern.
The lateral gray horn is a structure found in the spinal cord, specifically in the gray matter of the thoracic and upper lumbar regions. It contains neuronal cell bodies that are part of the autonomic nervous system, primarily responsible for processing and relaying autonomic functions, such as sympathetic nervous system activities. The lateral gray horn plays a crucial role in regulating involuntary bodily functions, including heart rate, blood pressure, and digestion.

The autonomic nervous system is controlled by nerve centers in the spinal cord and brain stem. It is also influenced by the midbrain and cortex, and the cognitive centers affect reactions such as blushing.Regarding the actual brain structure that contains autonomic centers regulating heart rate, respiration and other visceral activities, the answer is the medulla.*The medulla also is mainly composed of fiber tracts.
