chapter 11 mastering a and p
The somatic nervous system and the parasympathetic nervous system both release acetylcholine (ACh) onto their target tissues. Do you predict that this would indicate that these two pathways carry out the same effects? Why or why not? Choose the best answer.
No, because the receptors found on the target tissue for each pathway are different.
Which of the following best describes the direction and function of efferent signals?
away from the central nervous system, cause motor effects in glands or muscles
Muscarine, a chemical produced by certain mushrooms, binds to muscarinic receptors mimicking the effect of acetylcholine. How do you think administering this chemical would change body function? The drug would _____________.
change the functionality of certain exocrine and endocrine glands, change the functionality of the heart, and change the functionality of the smooth muscles within the digestive system
Which of the following is/are targets of the efferent nervous system?
smooth muscle, glands, cardiac muscle, skeletal muscle
A single neuron is stimulated at the central nervous system; this signal travels all the way to the target tissue, where the neurotransmitter acetylcholine is released onto the target tissue. The acetylcholine binds to a nicotinic receptor to induce skeletal muscle contraction. These steps describe the function of which branch of the efferent nervous system? Choose the best answer.
somatic
Which of the following are components of the efferent nervous system?
sympathetic neurons, somatic motor neurons, and parasympathetic neurons
