PNS Study Guide Flashcards
What are the five types of sensory receptors?
Mechanoreceptors, thermoreceptors, photoreceptors, chemoreceptors, and nocireceptors
What are the three locations of sensory receptors?
Exteroreceptors, interoreceptors, and proprioreceptors
What are the directions of nerves?
Mixed, afferent, and efferent
What are parts of a nerve?
Ganglia and connective tissues
What’s are the types of connective tissue layers of the nerve?
Epineurium, perioneurium, and endoneurium
What’s the rhyme to remember the cranial nerves?
On occasion, our trusted truck acts funny. Very good vehicle anyhow.
What’s the basic function of the troclear cranial nerve?
To pull on the eyes
What does the vestibular cochlear do?
It helps with balance and hearing
What does the glossophyringeal nerve do?
It helps swallow and senses the lyarinx
What does the vagus nerve do?
Control the gut and helps you talk
What does the accessory nerve do?
Controls the motor to the soft palate and neck
What does the hypoglossal nerve do?
Controls tongue movements
What nerves are sensory?
Olfactory, optic, and vestibular cochlear (on occasion violins)
What are the mixed nerves?
Facial, glossophyingeal, vagus, and trigeminal (Failing grades very trying)
Which nerves are motor?
Ocularmotor, troclear, abducems, hypoglossal, and accessory. (Over the ape has (an) apple)
How many spinal nerves are there? What types?
31; 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, 1 coccygeal
What are the differences between monosynaptic and polysynaptic reflexes?
Monosynaptic reflexes are quicker and only have one synapse
What’s the difference between ipsilateral and contralateral reflexes?
With ipsilateral, the reflex arc takes place on the same side the movement does
Where do parasympathetic and sympathetic nerves leave the CNS?
Parasympathetic leave the CNS with cranial nerves 3, 7, 9, and 10
