Meaning and Definition
The sheath of connective tissue that surrounds a bundle of muscle fibres (a fascicle).
In anatomical and histological contexts, it can more broadly refer to the dense layer of connective tissue that provides structural support, pathways for blood vessels and nerves, and contributes to the mechanical properties of the muscle.

FAQ
Frequently Asked Questions
No, it is a highly specialised anatomical term used only in medical, biological, and related scientific fields.
They are concentric layers of connective tissue in muscle: endomysium surrounds individual muscle fibres, perimysium surrounds bundles (fascicles) of fibres, and epimysium surrounds the entire muscle.
Not directly. It is a microscopic structure. However, the combined connective tissue framework (including perimysium) contributes to what we feel as the texture of meat or muscle.
It is most prominent and structurally organised in skeletal muscle. Cardiac muscle has a similar but less distinct connective tissue framework. Smooth muscle generally lacks a well-defined perimysium.

Memory Aids
Mnemonic
Think 'PERI' (around) + 'MYS' (muscle, as in 'myocardium') + 'IUM' (structure). So, 'the structure around the muscle bundle'.
Conceptual Metaphor
A PERIMYSIUM IS A WRAPPING/BUNDLING SHEATH, analogous to the plastic casing around a bundle of wires.
