Chapter 1 - Applied Anatomy and Physiology (1b - The Structure and Function of the Muscular System) Flashcards
Identify the muscles found at the hip.
- Hip flexors
- Gluteals
Which 2 muscles are located at the ankle joint?
- Tibialis Anterior
- Gastrocnemius
What are the two muscles found at the elbow?
- Bicep
- Tricep
Name at least 3 of the 5 muscles found in the shoulder joint (all 5 if possible).
- Deltoids
- Latissimus Dorsi
- Trapezius
- Pectorals
- Rotator Cuffs
A bicep curl is performed by a weight trainer. Identify which muscles in the antagonistic pair act as the agonist and the antagonist.
Agonist - Biceps
Antagonist - Tricep
State the definition of an agonist.
- The muscle that contracts to create movement.
State the definition of an antagonist.
- The muscle that relaxes to allow a movement to take place.
Give at least 3 examples of an antagonistic pair (give all 4 if possible)
- Biceps and Triceps
- Hip Flexors and Gluteals
- Hamstrings and Quadriceps
- Tibialis Anterior and Gastrocnemius
Give 2 examples of an isotonic contraction.
- Push ups
- Squats
- Bicep curls
- Walking up stairs
Give 2 example of an isometric contraction.
- Wall Sit
- Plank
- Front Support
What is a concentric contraction?
- A contraction when the length of the muscle is shortened.
What is a eccentric contraction?
- A contraction when the length of the muscle increases.
