A drug blocks the sympathetic division effect on the heart. Careful investigation reveals that, after the administration of the drugs, normal action potentials are produced in the sympathetic preganglionic and postganglionic neurons. Also, the injection of norepinephrine produces a normal response in the heart. Adequate information: The autonomic nervous system controls the unconscious movement of the body. It has two important divisions’ sympathetic and parasympathetic divisions. They are present on the preganglionic neuron of the CNS and autonomic ganglia of the PNS. The sympathetic axons travel through the sympathetic chain ganglia to their target cell. A ganglion is nerve cell bodies which are connected to one another in a series and form plexus. The sympathetic division has postganglionic neurons on several locations of ganglia. To determine: The mode of action produced by the unknown drug on the sympathetic division. Given information: The unknown drug produces the normal action potential on the sympathetic preganglionic and postganglionic neurons.

Summary Introduction

Case summary:

A drug blocks the sympathetic division effect on the heart. Careful investigation reveals that, after the administration of the drugs, normal action potentials are produced in the sympathetic preganglionic and postganglionic neurons. Also, the injection of norepinephrine produces a normal response in the heart.

Adequate information:

The autonomic nervous system controls the unconscious movement of the body. It has two important divisions’ sympathetic and parasympathetic divisions. They are present on the preganglionic neuron of the CNS and autonomic ganglia of the PNS. The sympathetic axons travel through the sympathetic chain ganglia to their target cell. A ganglion is nerve cell bodies which are connected to one another in a series and form plexus. The sympathetic division has postganglionic neurons on several locations of ganglia.

To determine:

The mode of action produced by the unknown drug on the sympathetic division.

Given information:

The unknown drug produces the normal action potential on the sympathetic preganglionic and postganglionic neurons.

All organisms need nitrogen in order to grow and repair. Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants. 7 Where else can plants obtain their nitrogen from? Plants make their own nitrogen. B Plants get it from animals. Plants get it from the soil.
