Muscular System Flashcards
What are the 3 types of muscles
Cardiac, Smooth, Skeletal
What is the definition of the Cardiac Muscle
It’s found in the heart and is oxygen dependant which is involuntary, and blood flows through the heart
What is the definition of the Smooth Muscle
The smooth muscle is found in multiple locations such as, blood vessels, lungs, and the digestive tract, which contracts in all directions. This can work without oxygen, which is involuntary, which aids digestions and he
Ps the flow of blood
What is the definition of the Skeletal Muscle
Found around the body, work with or without oxygen, works voluntarily, aids with movement
What are the main muscles of the muscular system
Deltoid, Trapezius, Latissimus Dorsi, Pectoralis Major, Biceps, Triceps, Rectus Abdominis, Glutes, Hip flexors, Quadriceps, Hamstrings, Gastrocnemius and Soleus
Muscles work in Antagonist and Agonist pairs what does this mean
Agonist- The muscle that is doing the work
Antagonist- The muscle that is not doing the work
There are 4 types of muscle contraction, Name them
Isotonic, Isometric, Concentric, Eccentric
Which type of contractions occur when the muscle changes length as it contracts and causes movements of a body part?
Isotonic
What type of muscle contraction occurs where the muscle shortens as it contacts.
Concentric
What type of contractions occur when the muscle lengthens as it contracts?
Eccentric
What type of muscle contraction occurs when the muscle remains the same length
Isometric
What is the type 1 twitch
Slow
What is the type 2 twitch
Fast
Which type twitch has a Slow resistance to fatigue which allows you to partake in longer aerobic exercises
Type 1
Which type has a High resistance to fatigue which means they cannot partake in long aerobic activities and only anaerobic
Type 2
