The route of major parasympathetic outflow from the head is via the .

Answer

Vagus (x ) Nerves

Explanation:

This is the longest of all cranial nerves extending from the brain to the abdomen. It originated from the brain stem. specifically in the medulla,and exit from the skull through the jugular foramen;together with the glossopharygeal and accessory nerves.

It emerges as the right and left vagus nerves at the base of the neck to give many branches. It extends to the thorax and the abdomen to give many other branches.

The correct answer is "vagus nerve".

Explanation:

The missing options of this question are:

A) sympathetic trunk

B) phrenic nerve

C) vagus nerve

D) sacral nerve

The correct answer is option C) "vagus nerve".

The vagus nerve, also known as pneumogastric nerve, is the tenth cranial nerve and is comprised only of parasympathetic fibres. This nerve covers from the brain through the face and thorax to the abdomen. Since the vagus nerve covers a major part of the body and it is comprised of parasympathetic fibres, it is the route of major parasympathetic outflow from the head.

answer: c. two haploid cells

explanation:

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
