4 syllables: neu, ri, lem, ma. Stress on lem.

Say it backNeurilemma refers to the outermost layer of the myelin sheath surrounding a peripheral nerve, also called the Schwann cell sheath. It forms the neurilemmal membrane that aids nerve fiber regeneration after injury. The term is used mainly in histology and neurophysiology to describe this protective and regenerative layer.
"The neurilemma is essential for nerve repair after peripheral nerve damage."
"Researchers studied how the neurilemma influences axonal regrowth in rats."
"In certain neuropathies, the integrity of the neurilemma can affect recovery."
pronounce as ne-RIL-ə-mə with primary stress on the second syllable. IPA: US nəˈrɪləmə; UK nəˈrɪləmə; AU nəˈrɪləmə. Start with a schwa on the first syllable, then a stressed rhotic-ish /r/ followed by a light /ɪ/ and a neutral schwa /ə/ before final /mə/. The two unstressed vowels are reduced; keep the /r/ crisp but not overemphasized. Visualize: ne- RIL -ə -mə. You’ll hear the emphasis in scientific reading when the second syllable carries the beat.
Common errors: (1) Stress misplaced on the first syllable (ne- instead of -RIL-). Fix by marking the second syllable as primary stress. (2) Overpronouncing the middle vowel as /ɪ/ or /iː/ with a strong vowel; reduce to a quick /ɪ/ or schwa. (3) Rolling the 'r' too aggressively or making the 'l' overly clear; keep a soft, light /r/ followed by a clear but not harsh /l/. Practice with a slow, deliberate rhythm and then speed up while maintaining the syllable integrity.
In US English, you’ll hear nəˈrɪləmə with a rhotic /r/ after the first syllable. UK tends toward non-rhotic or lightly rhotic landing on /r/ with similar vowel colors but often crisper consonants; AU tends to similar US patterns but with slight vowel width differences and a more centralized /ə/ in the final syllable. Across all, the key is keeping the second syllable stressed and the /l/ light before the final schwa; avoid over-enunciating the final /mə/—let it glide. IPA anchors help compare rhoticity and vowel quality precisely.
The difficulty lies in the three-syllable structure with two light, unstressed endings and a stressed middle syllable, plus the cluster /l/ before a schwa at the end. The sequence /rəˈlɪl-/ can tempt speakers to misplace the stress or over-articulate the /r/ and /l/. The final /mə/ needs quick, neutral reduction. Mastery requires precise vowel reduction, a light r-coloring, and a clean, soft l before the final syllable. Practicing with slow tempo and careful mouth shaping helps stabilize the rhythm across accents.
The distinctive feature is the secondary composition of the second syllable containing /ˈrɪ/ with a rolled or tapped impression in some speakers, followed by a light /l/ and a reduced final /ə/ before /mə/. This creates a delicate balance between consonant clarity and vowel reduction. Paying attention to the mid-syllable vowel quality (/ɪ/ vs /i/) and keeping the /r/ soft but present helps you land the correct rhythm and avoid monotone or rushed delivery.

Neurilemma derives from the Greek neuron, ‘nerve,’ and lemma, ‘premise’ or ‘assumption,’ via Latinized forms in anatomy. The term first appeared in late 19th to early 20th century anatomical literature as scientists classified nerve coverings. The root neuron reflects nervous tissue, while lemma here indicates a sheath or covering part, distinguishing the outer Schwann cell layer from inner neural elements. The sense evolved to emphasize the protective, regenerative role of the outer nerve sheath surrounding peripheral fibers, particularly the Schwann cell–derived layer that supports axon regrowth. The anglicized form neurilemma is standard in neuroanatomy texts and is often contrasted with endoneurium (inner) and epineurium (outermost connective tissue surrounding a nerve). It remains a technical term used in histology, physiology, and pathology to describe this key component of peripheral nerve structure.
