A useful mnemonic for remembering the nerve supply to the extraocular muscles is: LR6SO4AO3. Figure 2. Schematic diagram of the actions of the extraocular muscles and their innervation. 2.

2022年1月12日 · Compression, demyelination, or ischemia of any of these nerves can result in cranial nerve palsies with restriction of ocular motility. “SO4LR6” sounds like a fast car name but is an easy mnemonic, which helps one recall :“Superior oblique is CN4, and lateral rectus is CN6.”

2021年9月27日 · If you are like me, you will need a quick reminder of the function of these three cranial nerves. I use the mnemonic “SO4LR6 everything else CN3”. Cranial Nerve 4: Trochlear nerve innervates the superior oblique muscle moving the …

2024年5月18日 · Supranuclear ocular movements can be subdivided into four subtypes, namely, saccades, pursuit, vestibulo-ocular and convergence (Table 16.1). A saccade is a quick, small-amplitude eye movement used to acquire a target. Saccades are …

The 3rd cranial nerve innervates all the extraocular muscles except the lateral rectus and superior oblique (LR6, SO4). It also controls the levator palpebrae muscle and supplies parasympathetics to the pupillary constrictor and ciliary muscles.
