AUTONOMIC NERVOUS SYSTEM.

The AUTOMATIC NERVOUS SYSTEM of the brain pathway innervates a variety of organs, including the adrenal medulla, that results in the release of catecholamines from the terminal of sympathetic nerves.

Explanation: The automatic nervous system is the involuntary part of the nervous system,it controls involuntary body functions example; increase in heart rate.

The automatic nervous system is divided into sympathetic and parasympathetic.

The two divisions work in a complementary manner to maintain involuntary functions in the body and homeostasis.

The activities of the automatic nervous system includes;control and coordination of breathing,blood pressure,water balance, digestion and metabolic rate.

The autonomic nervous system acts on the smooth muscles by controlling the diameter of smaller airways and blood vessels ,controls the rate and force of cardiac contraction in cardiac muscles and controls the volume of gastrointestinal secretions in glands that are responsible for it and also controls the secretion of epinephrine and norepinephrine by the adrenal medulla.

The postganglionic neurone of the autonomic nervous system has it's cell body in a ganglion and terminates in the organ or tissue it supplies.

Norepinephrine and epinephrine are usually the neurotransmitters that acts at the sympathetic effector organs.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
