A preganglionic sympathetic fiber traveling to the abdomen would synapse in which structures?
juin [17]

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.

1. Analyze Graphs What trend in the monarch population does the graph show?
Vlada [557]

Answer:

Let's analyze the graph.

we can see that in 1995, the total area occupied was around 8 he.

Then we have a steep increase, reaching a maximum in the year 1997, where the area occupied was 20 he.

After that the area decreases abruptly and remains (varying a little from year to year) around 5he

Now we can look at the year 2006, that year the area was around 5he, ut after that we can see an almost constant decrease in the area, where each year (except from 2010 to 2011) the area decreased.

Ending in 2014 near 1 or 2 hectares.

The conclusion that we can take from this graph is that, while some years ao the area fluctuated around some values, in recent years we can see a clear decrease in the area ocuppied by the Overwintering Monarchs.
