GSA and GVA
Which cranial nerve gives rise to the superior and inferior cervical cardiac branches?
Vagus nerve
Which fibers carry taste sensations from the epiglottis?
SVA
Which division of the autonomic nervous system supplies blood vessels?
Sympathetic division
Which division of the autonomic nervous system supplies the heart?
Both divisions
What is the main effect of parasympathetic stimulation on the heart?
Decrease strength of contraction
What is the main effect of sympathetic stimulation on the heart?
Increase heart rate
What is the difference between an injury to a perivascular nerve bundle and an injury to a paravascular nerve?
Perivascular nerves run along the arteries, while paravascular nerves supply the arteries themselves
Which of the following accurately describes the innervation of the cardiovascular system?
The cardiovascular system is innervated by both the sympathetic and parasympathetic nervous systems.
What are the two divisions of the autonomic nervous system involved in cardiovascular innervation?
Parasympathetic and sympathetic divisions
Which of the following is primarily responsible for motor (efferent) control in the autonomic nervous system?
Sympathetic nervous system
What is the general effect of sympathetic innervation on target organs in the cardiovascular system?
Increased heart rate and blood pressure
What is the role of autonomic pathways in mediating referred pain from the heart?
Autonomic pathways indirectly contribute to the perception of pain from the heart.
Which cranial nerve contains both motor and sensory fibers?
Cranial nerve IX
Where does the Glossopharyngeal Nerve exit the central nervous system?
At the medulla
Which nerve supplies structures in the head and neck as far inferiorly as the lower pharynx?
Glossopharyngeal Nerve (Cranial nerve IX)
Which fiber type of the Glossopharyngeal Nerve carries somatic sensations from the skin of the external ear and oropharynx?

What is the location of the cardiac plexus?
At the base of the heart
What other structures is the cardiac plexus near and thus vulnerable to injury if they are affected by a disease process?
The tracheal bifurcation
What is the function of the parasympathetic fibers in the cardiac plexus?
To decrease the rapidity and force of contractions
Which of the following accurately describes the pathway of GVA fibers from the heart to the spinal gray matter?
