A special group of chemical substances that are used to treat diseases caused by microbes are called antibiotics.
An antibiotic is a chemical compound that is toxic to other bacteria and is produced by a living thing, usually a bacterium. In a complex environment like soil, organisms undoubtedly use antibiotics to regulate the growth of competing microbes. Soil microorganisms frequently produce antibiotics.
Bacteria and fungi are microorganisms that produce antibiotics that help prevent or treat disease. With the invention of penicillin in 1941, antibiotics gained widespread recognition. Since then, they have fundamentally changed how bacterial infections in humans and other animals are treated.

Answer:
Answered below.
Explanation:
The nerve fibres of the autonomic nervous system that connects the ganglia to the the central nervous system are called preganglionic fibres. They are divided into sympathetic preganglionic fibres and parasympathetic preganglionic fibres and both have acetylcholine as their neurotransmitter.
The sympathetic preganglionic is shorter compared to the parasympathetic preganglionic fibres. They originate from the hypothalamus and brainstem and project to the ganglia non the spinal cord. A ganglion is a cluster of nerves outside the central nervous system.
The preganglionic sympathetic fibres originating from T1-T2 innervate the cervical ganglion which innervates the muscles of the pupils (dilators).
The postganglionic fibres originating from the preganglionic fibres of T11-L3 passes through splenic, celiac and mesenteric ganglia to innervate the kidneys and renal vessels.
