Karten in diesem Stapel (24)
- 1What is the neurotransmitter associated with the somatic nervous system?Acetylcholine
- 2How many neurons are present in a chain from the spinal cord to the effector organ in the somatic nervous system?1
- 3How many neurons are present in a chain from the spinal cord to the effector organ in the autonomic nervous system?2
- 4What are the 2 divisions of the autonomic nervous sytem?Sympathetic and parasympathetic
- 5Smooth muscle, cardiac muscle, and glands are under control of the (somatic/autonomic) nervous system.autonomic
- 6Which branch of the nervous system can be described as self-regulating?Autonomic
- 7What is/are the primary neurotransmitter(s) of the parasympathetic nervous system?Acetylcholine (of both the pre- and post-synaptic neurons)
- 8The parasympathetic nerves originate from which areas of the vertebral column? Sympathetic?-Para: Craniosacral (cranial nerves and sacral spinal cord)
-Sympathetic: Thoracic and lumbar - 9What are the 4 cranial nerves that are controlled by the parasympathetic nervous system?-III: Oculomotor
-VII: Facial
-IX: Glossopharyngeal
-X: Vagus - 10Where does the vagus nerve provide voluntary motor control? Sensory? Parasympathetic?-Voluntary motor: Muscles of the pharynx, larynx, and cranial esophagus
-Sensory: Skin of outer ear
-Parasympathetic: Throughout the thorax and abdomen (caudal esophagus). Major importance in regulation of heart, lungs, GI tract, etc - 11Where does the facial nerve provide voluntary motor control? Sensory? Parasympathetic?-Voluntary motor: Facial expressions. Caudal/Posterior digastricus m.
-Sensory: Taste buds (special sensory)
-Parasympathetic: Lacrimal (tear) glands. Sublingual and mandibular salivary glands - 12What are the sacral segments where the parasympathetic division originates from?S2, S3, and S4
- 13In the 2 neuron synapse of the parasympathetic nervous system, where are the 1st and 2nd cell bodies found?-1st cell body is in the CNS- craniosacral area (pre-ganglionic)
-2nd cell body is in the wall of the organ being innervated (post-ganglionic) - 14In the parasympathetic nervous system, are the pre- or post-ganglionic fibers longer?Pre
- 15What is/are the pre- and post-synaptic neurotransmitters of the sympathetic nervous system?-Pre: Acetylcholine
-Post: Norepinephrine, noradrenaline - 16Where do sympathetic nerves originate in dogs and humans?-Thoracolumbar spinal cord
-Dogs: T1-L4
-Humans: T1-L2 - 17Where specifically is the first neuronal cell body in the sympathetic nervous system?Lateral horn of gray matter
- 18The white and gray rami are associated with which branch of the nervous system? What are they, and what are characteristics of each?-Sympathetic nervous system
-White: Preganglionic axon. Myelinated
-Gray: Postganglionic axon. Unmyelinated - 19A presynaptic neuron in the sympathetic nervous system will synapse in one of these 2 places:-Sympathetic trunk
-Prevertebral ganglia (ie Celiacomesenteric ganglion, Caudal mesenteric ganglion)
-Will never synapse in both of these - 20The adrenal glands are controlled by which branch of the nervous system?Sympathetic
- 21Where are epinephrine and norepinephrine released from? What triggers its release?-Renal medulla
-Acetylcholine being released at the medulla triggers its release - 22The preganglionic axons of the parasympathetic division are (myelinated/unmyelinated). The postganglionic axons of the parasympathetic division are (myelinated/unmyelinated).-lightly myelinated
-unmyelinated - 23Axons of the somatic nervous system are (heavily myelinated/lightly myelinated/nonmyelinated).Heavily myelinated
- 24Ganglia (as in, sympathetic chain ganglia) are part of the (PNS/CNS).PNS
