Exam 11: Efferent Division: Autonomic and Somatic Motor Control

In a laboratory experiment, adding curare, which binds to acetylcholine receptors, to the solution around a muscle decreases the size of the end-plate potential.Adding prostigmine, an acetylcholinesterase blocker, increases the size of the end-plate potential.Explain why.

________ are swellings that contain vesicles filled with neurotransmitter.

Map the divisions of the autonomic nervous system down to their receptors.

The division of the autonomic nervous system that prepares the body for intense levels of activity and stress is the

Which tissues contain both cholinergic and adrenergic receptors, and how does this relate to their autonomic control?

The two divisions of the efferent side of the peripheral nervous system are

The two varieties of adrenergic receptors are ________ and ________.

Match the following with its description. -primary sympathetic neurotransmitter

Anne Frank wrote a diary about the years she and a few others spent in hiding from the Nazis during World War II.These people lived in the upstairs rooms of a shop, accessible only by a hidden stairway; Anne called these quarters the Secret Annex.One day Nazis raided the shop below, but were unsuccessful in locating the hideaways or finding proof of their presence during this particular raid.Clearly hearing what was occurring downstairs, Anne and her cohorts cowered in silence, for they feared being transported to "death camps." Later, Anne wrote that most of the residents of the Secret Annex experienced diarrhea shortly after this close call.Explain this response by their digestive systems.

Match the answers to the questions. -It is important during stress or emergencies (fight-or-flight).

Match the answers to the questions. -It dominates during resting-and-digesting activities.

Match the answers to the questions. -On average, one preganglionic neuron synapses with eight or nine postganglionic neurons, each innervating a different target.

To perform surgery with a minimum of pain for the patient and hassle for the surgeon, a patient may be administered a general anesthetic to prevent sensation and consciousness, as well as a paralytic to prevent reflexive muscle spasms.From what you have learned of motor control, suggest mechanisms by which a paralytic can prevent muscle contraction.With paralytics, what extra measure must be taken to keep the patient alive? Name such a paralytic agent.

Autonomic neurotransmitters are synthesized in the ________.

Cholinergic nicotinic receptors are found in the ________ of the ANS.

Match the following with its description. -target receptor for preganglionic neurons

Match the response with the type of chemical. -blocks urination

Match the answers to the questions. -The ganglia are found in a chain that runs close to the spinal cord or along the descending aorta.

________ postganglionic sympathetic neurons secrete ________ onto their target cells.

The ________ is the major source of parasympathetic output.
