What is Posture?
What is a tendon?
The outer covering of a fascicle
What is the Perimysium?
The smallest functional unit of a muscle

This ion is essential for muscle contractions
What is calcium?
This function is used when we dance or wave our arms
What is mobility?
This thing is the anchor that muscles are attached to
What is a bone?
The outer covering of a muscle fiber

This is the 'scientific term' for wasting away due to underuse
This function is used to help keep our shoulder joint structured
This is the middle of a muscle
What is a belly?

What is an eccentric contraction?
This function is used to 'shield' your organs
What is organ protection?
This is the head of a muscle that does not move when the muscle contracts
What is origin?
A collection of these make up a muscle
What is a fascicle?
This protein blocks the myosin from reaching actin
This type of muscle is only found in the heart
What is cardiac muscle?
This function is used when we shiver
This is the outer covering of a muscle
What is the epimysium?
What is a myocyte?
This protein is attracted to calcium, and pulls another protein out of the way to allow myosin to grab actin
This type of contraction is when our muscle length does not change as our muscles are being used
What is an isometric contraction?
