How do you remember the spinal nerves?
A useful mnemonic for remembering the relationships in the spinal cord is: SAME-DAVE (sensory-afferent, motor-efferent; dorsal-afferent, ventral-efferent). In the thoracic region, the upper lumbar region and in segments of the sacral region of the spinal cord, there is also a lateral horn of gray matter.
What would be a clever way to remember the 12 cranial nerves?
Some say marry money but my brother says big brains matter more (mnemonic)…Mnemonics
- O: olfactory nerve (CN I)
- O: optic nerve (CN II)
- O: oculomotor nerve (CN III)
- T: trochlear nerve (CN IV)
- T: trigeminal nerve(CN V)
- A: abducens nerve (CN VI)
- F: facial nerve (CN VII)
- A: auditory (or vestibulocochlear) nerve (CN VIII)
What are the 10 cranial nerves?
The nerves are: the olfactory nerve (I), the optic nerve (II), oculomotor nerve (III), trochlear nerve (IV), trigeminal nerve (V), abducens nerve (VI), facial nerve (VII), vestibulocochlear nerve (VIII), glossopharyngeal nerve (IX), vagus nerve (X), accessory nerve (XI), and the hypoglossal nerve (XII).
What is the first cranial nerve called?
The olfactory nerve, or cranial nerve I, is the first of the 12 cranial nerves. It is instrumental in the sense of smell. The olfactory nerve is the shortest of the 12 cranial nerves and only one of two cranial nerves (the other being the optic nerve) that do not join with the brainstem.
How do you make a mnemonic?
- Take the first letter or a key word of the item to remember and write it down.
- Repeat for all items.
- Create a sentence.
- Write the sentence out a few times while saying the words that the acronym refers to.
- Practice reciting the items and the created sentence together until you’ve got it memorized!
Which is a consequence of AICA or pica dominance?
The AICA-PICA balance in extent of cerebellar territory capture is a consequence of either anterior spinal (AICA) or lateral spinal (PICA) dominance. All of these cases are given angiographic illustrations below. For a clinical case, see Lateral Spinal Artery Aneurysm.
How to tell if you have PICA or AICA?
If it’s PICA (lateral medullary syndrome), you might see some hoarseness, gag reflex problems. If it’s AICA, say good bye to all the facial muscles
Is the AICA homologous to the basilar artery?
At the mid to lower basilar segment, a homologous enlarging channel is the AICA. At the bottom, the Posterior Inferior Cerebellar Artery (PICA) is the latest addition to cerebellar supply, Unlike AICA and SCA, it seems to arise from the lateral spinal system (yet nervertheless also a coronary artery homolog).
Where is the AICA located in the cerebellum?
AICA generally arises from the caudal third of the basilar artery and supplies the lateral pons, inner ear, middle cerebellar peduncle and the anterior inferior cerebellum 4,5. AICA territory infarcts are rare, comprising ~1% of ischaemic cerebellar strokes 2 .
