medulla oblongata
autonomic nervous system.
The lower portion of the Brain Stem is called the Medulla Oblongata. Its job is to control Cardiac and Respiratory Centers and deals with autonomic and involuntary functions such as breathing, heart rate, and blood pressure.
Most motor functions
Autonomic reflexes
autonomic system
If they weren't autonomic you would have to think about controlling the things they control like blood pressure, heart rate, digestion, or anything automatic. Either you're head would explode from your brain having to be so big or it would overload itself and implode.
autonomic nervous system.
The medulla is found in the cardiovascular center of the brain and controls receptors in the body to control homeostasis (physical conditions such as temperature within the body).
The hypothalamus influences the autonomic centers in the brain stem and the spinal cord. In this way it regulates many Visceral activites such as heart rate, blood pressure respiratory rate and motility of digestive tract
They are responsible for digestion. They are also part of the autonomic nervous system, so you do not have to consciously control them.
Because they are controlled by the autonomic nervous system which is responsible for involuntary control of the heart and digestion (as well as breathing and such). If you had to voluntarily control your digestion or heart rhythm you wouldn't survive very long.
It controls involuntary actions such as heart rate, digestion, respiration rate, salivation, perspiration, sexual arousal, and urination.
it controlls heartbeat, breathing rate, blood pressure and body temp. Invoulantay .
The function of the autonomic nervous system is to control involuntary actions, or body functions that must operate even without conscious awareness of those functions. It regulates heart activity, acting like brakes and accelerators to decrease or increase the heart rate.
It's also known as "visceral nervous system" which unconsciously and involuntary controls your visceral functions (heart and respiration rates, digestion, salivation, and many others).
The somatic nerves control the voluntary cells which are under conscious control. If you want to walk, and do so, this is a voluntary motion. The autonomic nerves control the involuntary motions of your body. These nerves keep check of your body by maintaining temperature, composition of blood, heart beat, digestion, and excretion. These are actions that you do not think about. Even stress when your blood pressure, pulse rate, and blood sugar become elevated, is controlled by the autonomic nerves. The somatic and autonomic systems work together. Skin exposed to cold air becomes "blue," this is autonomic. At the same time impulses are sent to the brain for sensations of cold, this is somatic.
Parts of the body that do what they do on their own without us having to think about it or causing it to happen. Breathing, blood circulating and food digestion are all part of the autonomic system.
