Chapter 6 Flashcards
What are the three types of muscle tissue
smooth
cardiac
skeletal
What is a smooth muscle and where are smooth muscles located
They’re smooth, involuntary muscles which surround the body’s internal organs
What is a cardiac muscle and where are cardiac muscles located
They are found only in the heart and they are responsible for pumping blood blood throughout the body. They are involuntary
What is a skeletal muscle and where are skeletal muscles located
These muscles are the type of muscles that are attached to the bones (by tendons and other tissues) and are voluntary muscles
What are the types of muscle contractions
Concentric Contration (Isotonic) - > Shortening Eccentric Contraction (Isotonic) - > Lengthening Isometric Contraction - > Static
How are skeletal muscles named?
Based off…
- Action of the muscle
- Direction of the fibres
- Location of the muscle
- Number of divisions/threads
- Shape of the muscle
- Muscle’s point of attachment
What are the major ANTERIOR muscle groups
- Quadricep group
- Rotator cuff group
- Abdominals
- Pectorial Muscles
What are the major POSTERIOR muscle groups
- Erector Spinae group
- Rhomboids
- Gluteals
- Hamstring group
- Calf Muscles
What is an agonist muscle
It’s the muscle primarily responsible for movement of a body part
What is an antagonist muscle
The muscle that counteracts the agonist, lengthening when the agonist muscle contracts
What do muscles never do
PUSH
Name an example of an agonist-antagonist muscle pair
When doing a bicep curl, the bicep is the agonist and the tricep is the antagonist
What is a muscle origin
The point where the muscle attaches to the more stationary of the bones in the axial skeleton
What is a muscle insertion
The point where the muscle attaches to the bone that is moved most
