Muscles Of The Body And Their Work Flashcards
Name the muscles in your arm and point to them
Rotator cuffs and deltoid
Biceps and triceps
Name the muscles in your tummy and back
Trapezius
Pectorals
Latissimus dorsi
Abdominals
Name the muscles from your hips to your ankles
Hip flexors Gluteals Quadriceps group Hamstring group Tibialis anterior Gastrocnemius
What is a tendon
A connective tissue which connects a muscle to a bone
It results in bone movement from the contacting muscle to bone
What muscles move at the shoulder
Trapezius Rotator cuffs Deltoid Biceps triceps Pectorals Latissimus Dorsi
What muscles move at the elbow and knee
Elbow= biceps and triceps Knee= quadriceps and hamstrings group
What muscles work at the hip
Hip flexers
Gluteals
What muscles work at the ankle
Tibialis interior
Gastrocnemius
Definition of antagonistic pairs
Muscles can only pull and not push so they work in pairs which are either side of the joint
Meaning one contacts and pulls while the other relaxes
In antagonistic pairs what’s the muscles called if they are:
Contracting
Or
Relaxing
Contracting= prime mover (agonist) Relaxes= antagonist
Give an example of muscles working in antagonistic pairs at biceps and triceps
The biceps and triceps
Flexion > biceps = prime move
Tricep = antagonist
Extension > ^ opposite
What is an isotonic contraction
What are the two types that this can be
Occur when a muscle changes in length when contacting
Concentric
Eccentric
Isometric contraction definition
Occur when muscles stay the same length
There is no actual movement so to keep joint stationary
What is concentric contraction
When the muscle contracts and shortens
What is eccentric contraction
When the muscle contracts and lengthens
