MUSCLE in Spanish: MÚSCULO
Músculo · noun · MOOS-koo-loh
Músculo is a near-perfect cognate of the English 'muscle,' making it one of the easiest anatomy words to learn. It applies to every context—gym conversations, medical exams, biology class, and even figurative speech about organizational or political 'muscle.' The trickiest part is pronunciation: the accent falls on the first syllable (MOOS-koo-loh), and forgetting the accent mark in writing changes the rhythm of the word entirely.
MOOS-koo-loh
Me duele el músculo de la pierna después de correr.
My leg muscle hurts after running.

Avoid These Mistakes When Using Músculo
Dropping the accent mark
Incorrect: Tengo dolor de musculo.
Correct: Tengo dolor de músculo.
The accent mark on the first 'u' is essential because músculo is an esdrújula word (stress on the third-to-last syllable). Dropping the accent changes the stress pattern.
Confusing músculo with muslo
Incorrect: Me lesioné el muslo (meaning muscle).
Correct: Me lesioné el músculo.
Muslo means 'thigh,' a specific body part, while músculo means 'muscle' in general. They sound similar but refer to different things.
