1
Q

What are the three types of muscle tissue

A

smooth
cardiac
skeletal

2
Q

What is a smooth muscle and where are smooth muscles located

A

They’re smooth, involuntary muscles which surround the body’s internal organs

3
Q

What is a cardiac muscle and where are cardiac muscles located

A

They are found only in the heart and they are responsible for pumping blood blood throughout the body. They are involuntary

4
Q

What is a skeletal muscle and where are skeletal muscles located

A

These muscles are the type of muscles that are attached to the bones (by tendons and other tissues) and are voluntary muscles

5
Q

What are the types of muscle contractions

A
Concentric Contration (Isotonic)
- > Shortening
Eccentric Contraction (Isotonic)
- > Lengthening
Isometric Contraction
- > Static
6
Q

How are skeletal muscles named?

A

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
7
Q

What are the major ANTERIOR muscle groups

A
  • Quadricep group
  • Rotator cuff group
  • Abdominals
  • Pectorial Muscles
8
Q

What are the major POSTERIOR muscle groups

A
  • Erector Spinae group
  • Rhomboids
  • Gluteals
  • Hamstring group
  • Calf Muscles
9
Q

What is an agonist muscle

A

It’s the muscle primarily responsible for movement of a body part

10
Q

What is an antagonist muscle

A

The muscle that counteracts the agonist, lengthening when the agonist muscle contracts

11
Q

What do muscles never do

A

PUSH

12
Q

Name an example of an agonist-antagonist muscle pair

A

When doing a bicep curl, the bicep is the agonist and the tricep is the antagonist

13
Q

What is a muscle origin

A

The point where the muscle attaches to the more stationary of the bones in the axial skeleton

14
Q

What is a muscle insertion

A

The point where the muscle attaches to the bone that is moved most
