Chapter 15 Lecture Quiz Flashcards
The division of the peripheral nervous system that controls the body’s skeletal muscles is
Somatic nervous system
The efferent neuron of the ANS that comes before the autonomic ganglion is called the ____________ Neuron.
Preganglionic
The efferent neuron of the ANS that comes after the autonomic ganglion is called the ____________ Neuron.
postganglionic
The effectors of the ANS are innervated by the _____________ Neuron.
postganglionic
Effectors of autonomic nervous system are all of the following except
skeletal muscle
skeletal muscle
sympathetic division
This division of the ANS originates from the thoracolumbar region of the spinal cord.
sympathetic nervous system
This division of the ANS has a long postganglionic neuron.
sympathetic division
This division of the ANS is involved with salivation
parasympathetic division
This division of the ANS has a long preganglionic neuron
parasympathetic division
This division of the ANS is will cause pupil constriction.
parasympathetic division
This division originates in craniosacral region
parasympathetic division
This division of the ANS has a neurotransmitter that binds to adrenergic receptors on the effectors.
sympathetic division
Which of the following is true?
The parasympathetic division of ANS is also known as the craniosacral division
Which of the following is not true?
Parasympathetic nerves innervate arrector pili and blood vessels of the dermis
The parasympathetic nervous system could me anatomically referred to as the
Craniosacral division
The primary neurotransmitter of parasympathetic nervous system is
Acetylcholine
Which of the following would not be expected during a “ fight or flight” response?
Increase in digestive activity
An increase of sympathetic activity will cause airway diameter to
increase
Which of the following statements concerning the parasympathetic division of ANS is false?
Preganglionic fibers are short and postganglionic fibers are long
Which of the following is an example of visceral reflex?
Vomiting reflex
Defecation reflex
Pupillary reflex
The suprarenal medullae secrete
Epinephrine
Preganglionic fibers of parasympathetic neurons are present in all of the following cranial nerves, except
XII
Almost 75% of all parasympathetic outflow travels along the
Vagus nerve
Epinephrine binds to
Adrenergic receptors
Given these parts of an autonomic reflex:
- afferent neuron
- association neuron (integrating center)
- effector cell
- efferent neuron
- sensory receptor
Choose the correct order an action potential travels through them from a stimulus to the resulting action.
5,1,2,4,3
Which of these structures is innervated almost entirely by the sympathetic division?
blood vessels
Which of the following actions is caused by skeletal muscle
Eye movement
