  1. What are antagonistic muscles? Antagonist? Agonist? (open note content)

→ 1 (or more) muscle contracts to move a body part in 1 direction, then different muscles contract to move the same body part in the other direction while the other muscles relaxes

Agonist = muscle that is contracting / shortening 

→ Antagonsit = muscle that is relaxing / lengthening

  1. Describe the difference between origins and insertions. How are they used in moving the body? You will not be asked about the origins / insertions of specific muscles on the exam. (open note content) → Origin is relatively the less movable end of the muscle/tendon that is attached to a bone. Insertion is the more flexible end of the muscle that is usually attached to a bone via tendons. It is the proximal end that is attached to the less movable bone. It is the distal end that is attached to the more movable bone.
