his statement about the activation of α1-

and β1- adrenergic receptors is correct:

Given these parts of an autonomic reflex:

1. afferent neuron

This structure is innervated almost

exclusively by the sympathetic division:

a. gastrointestinal tract

b. heart

c. urinary bladder

d. reproductive tract

e. blood vessels

BACK TO GAME

e

This is the response to a sudden increase in

blood pressure:

a. sensory neurons send action

potentials to the medulla oblongata

b. the frequency of action potentials

decrease to sympathetic nerve fibers

c. blood vessels dilate

d. all of these BACK TO GAME

An example of a local reflex that occurs in

the digestive tract follows these steps:

1. the digestive tract is stretched

2. enteric sensory neurons

3. enteric interneurons

4. enteric motor neurons

5. stimulation of glands to secrete

True/False

true

The sympathetic division produces only

excitatory effects while the

parasympathetic division produces only

inhibitory effects.

True/False

false

These organs/systems have dual

innervation except:

a. gastrointestinal tract

b. heart

c. urinary bladder

d. sweat glands

e. reproductive tract

BACK TO GAME

d

When the sympathetic division is activated

through exercise, this happens:

a. vasodilation of blood vessels

b. tear production increases

c. air passageways dilate

d. glucose release from the liver decreases

e. a and c

f. all of these

e

The parapsympathetic division controls

this:

a. defecation

b. urination

c. increased secretion of glands

d. constricts air passageways

e. all of these

BACK TO GAME

e

A patient suffering a myocardial infarction

(heart attack) has cold, clammy skin

because of strong stimulation of this:

a. parasympathetic division

b. sympathetic division

BACK TO GAME

b

This describes the autonomic nervous

system except:

a. targets are smooth/cardiac muscle

and glands

b. can stimulate or inhibit target tissues

c. contains 2 neurons in a series
