EG Antagonistic Pair

• give an example of an antagonistic pair?

  bones of lower arm attached to a biceps muscle and a triceps muscle by TENDONS

  • The biceps & triceps work together to move arm- as one contracts, the other relaxes
• What happens when your BICEPS contracts?


  Your triceps relaxes

  • this pulls the bone so your arm bends (FLEXES) at the elbow
  • here, the biceps is the agonist
  • the triceps is the antagonist
• What happens when your TRICEPS contracts?


  your biceps relaxes

  • this pulls the bone so arm straightens (extends) at the ELBOW
  • Here, the triceps = agonist
  • biceps is the antagonist
