What is perimysium?
Each fasiculus or bundle is surrounded by connective tissue called perimysium
What is epimysium?
Fibres within each bundle are surrounded by more connective tissue called endomysium

Perimysium & Endomysium
What are the skeletal muscle actions and muscular compartments?
Agonist - prime mover (muscle contraction chiefly responsible for a movement)
Antagonist– opposes an agonist, its function is opposite
Synergist– helps an agonist
Fixator– stabilises prime mover
Function of a tendon is?
To attach muscle to bone
An aponeurosis is?
A broad strand of connective tissue that attaches muscle to fascia/muscle to bone/muscle to muscle.
Gross anatomy of a muscle is important for function
Sites of attachment
