kin quiz muscles Flashcards
muscle function
- contraction for locomotion and skeletal movement
- contraction for propulsion
- contraction for pressure regulation
cardiac muscles
- make up your heart
- characteristics of both smooth and skeletal muscles
- fatigue resistant and contractions are involuntary
skeletal muscles
- attached to bone and responsible for supporting and moving the skeleton
- contracting under voluntary control by motor neurons
- group of muscle fibers bound together by connective tissue
- held to bones by the help of tendons
- capable of rapid contraction and relaxation
muscle pairs
muscles work together and can only pull, cannot push
- these pairs are called antagonistic pairs
- as one muscle contracts, the other relaxes
agonist
muscle that is contracting (also called prime mover)
antagonist
muscle that is relaxing
synergist
help to stabilize the bone which isn’t moving (safe bet is abdominals)
calves
tibialis anterior
quadriceps
hamstrings
hip flexors
gluteals
erector spinae
abdominals
pectoralis major + minor
upper back (trapezius, rhomboids)
latissimus dorsi
deltoids
biceps brachii
triceps brachii
ex. Hamstring curl
what is agonist, antagonist, and synergist
