muscles
Bodybuilder's prized assets
Muscles are the fibrous tissues in animal bodies that contract and relax to produce movement.
The human body contains hundreds of muscles, from the large ones that move limbs to the tiny ones that focus eyes.
Beyond anatomy, muscles often stands for physical strength or power: Put some muscle into it.
Someone who muscles their way through a crowd uses physical force; to muscle in on something is to intrude aggressively where you're not wanted.
A person who provides muscle for an operation supplies intimidation or enforcement rather than brains.
