What type of medication could be given to a patient to help lower their high blood pressure? 1. Alpha antagonist 2. Alpha agonist 3. Muscarinic agonist 4. Muscarinic antagonist 5. Beta agonist 6. Beta antagonist

1, 3, and 6

Using the information you know about the autonomic nervous system, interpret the graph below and determine which of the following would be an accurate label for the X-axis. 1. Acetylcholinesterase 2. Acetylcholinesterase inhibitor 3. Adrenal medulla stimulation 4. Vagus nerve stimulation

2 and 3

Using the information you know about the autonomic nervous system, interpret the graph below and determine which of the following would be an accurate label for the X-axis. 1. Acetylcholine 2. Beta-1 receptors 3. Beta-2 receptors 4. Epinephrine 5. Muscarinic antagonist

2, 4, 5

Which would have a more widespread effect on the body (interfering with normal function)?

A poison binding the nicotinic receptors

Which of the following is the neurotransmitter associated with autonomic ganglia?

Acetylcholine

Using the information you know about the divisions of the autonomic nervous system, interpret what is occurring at letter

At point A, this patient may also have a flatter lens in their eye.

Using the information you know about the divisions of the autonomic nervous system, interpret what is occurring at letter B.

At point B, this patient may also have increased gastric motility.

A pheochromocytoma is a tumor found on the adrenal gland that leads to an increased release of catecholamines. Which of the following signs and symptoms would you not expect to see in a patient with a pheochromocytoma?

Increased gastric motility

Stimulation of the autonomic nervous system results in insulin secretion from the pancreas during and after a meal. Based on this information, which of the following statements is most likely to be true?

Increased insulin secretion is due to parasympathetic stimulation Acetylcholine agonists will stimulate insulin secretion

Which of the following is incorrectly matched?

Parasympathetic: Generalized sweating

Which of the following would occur during the "fight or flight" response?

Reduced urinary output

Which division of the nervous system controls the radial muscles of the eye?

Sympathetic

The excitatory or inhibitory effect of a postganglionic sympathetic fiber is determined mostly by which of the following features or structures?

The type of adrenergic receptor to which it binds

Using the information you know about the divisions of the autonomic nervous system, interpret the following graph.

This patient was given a beta agonist at point B. and This patient was given a muscarinic antagonist at point B.

An example of an inhibitory effect from sympathetic stimulation is

a decrease is respiratory smooth muscle contractions

Atropine is ___________ antagonist sometimes used to dilate the pupil for an eye examination.

a muscarinic

Administration of atropine, a muscarinic antagonist, would

block constriction of the pupil

Blocking adrenergic receptors prevents airway

dilation

Beta-2 adrenergic receptor antagonists prevent _____________ ; and muscarinic antagonists prevent __________ of the bronchioles.

dilation, constriction

The effect of increased thin or watery saliva secreted of the salivary glands is a result of

parasympathetic stimulation
