-splanchnic nerves (sympathetic/parasympathetic)
-neurons traveling through cranial nerves (sympathetic/parasympathetic)
-autonomic ganglia in the head (sympathetic/parasympathetic)

The autonomic nervous system consists of:
The sympathetic and parasympathetic divisions
The cerebral hemisphere and the corpus callosum

The cerebellum and medulla oblongata
The brain and spinal cord
Classify the following characteristics to demonstrate your knowledge of differences between the autonomic and somatic divisions of
the nervous system.

to nicotinic acetylcholine receptors located
on the effector organs

responsive to epinephrine that is released
into the blood by the adrenal medulla

Listed below are different symptoms or complications that can be attributed to something from the nervous system. List the specific structure that is most likely the root cause of the pathology. In addition, label which branch of the nervous system that structure is a part of (CNS or PNS). I suggest making a table with the pathology in one column, the affected structure in the next column, and the nervous system section in the final column. Two examples are below. It is possible that more than one answer could be correct. Pathology/Patient Specific Structure CNS or PNS?

Often, the action potentials occur sorapidly that watching a screen to see them occur is nothelpful. A speaker is powered by the signals recorded froma neuron and it “pops” each time the neuron fires an actionpotential. These action potentials are firing so fast that itsounds like static on the radio. Electrophysiologists canrecognize the patterns within that static to understand whatis happening.

- Which division(s) of the nervous system involve neuromuscular junctions? (Choose ALL that are correct) Group of answer choices Visceral motor Visceral sensory Somatic motor Somatic sensoryarrow_forwardThere are two divisions of the autonomic nervous system: Sympathetic and parasympathetic Describe in detail the pre and post ganglionic fibers, location of the ganglia, neurotransmitters and receptors associated with each systemarrow_forwardWhich of the following statements regarding the motor end plate in the somatic motor division of the nervous system is true? After the activation of voltage-gated calcium channels, the neuron releases ACh onto the muscarinic receptors on the surface of the highly folded area of the muscle fibre. The preganglionic nerve fibre releases ACh onto the postganglionic nerve fibre, which then releases ACh onto the cholinergic receptors of the motor end plate. Chemically gated monovalent cation channels on the motor end plate are activated once the motor neuron releases ACh onto the nicotinic receptors on the surface of the muscle cell. The AChE enzyme enhances the amount of ACh released into the neuromuscular junctionarrow_forward
