What are the three types of muscle tissue?
Skeletal, smooth, cardiac
How are skeletal muscles attached?
To the bone via tendons
What are skeletal muscles?
Are attached to the bone and are known as voluntary muscles.
What type of cells make up the skeletal muscles?
Striped and striated
What are cardiac muscles?
Make up walls of the heart and are involuntary as you have no control over them
What type of cells make up cardiac muscles?
Striped in appearance
What is a smooth muscle?
Found in the blood vessels and walls of the intestines. They are involuntary
What cells make up the smooth muscle?
Spindle
What are the functions of muscles?
- provide support and maintain posture
- stability
- pump blood
- heat production
What is isometric muscle action?
A muscle contraction against a force with no significant movement. Tension is produced but no joint movement occurs.
What is an isokinetic muscle action?
The speed or velocity of movement is held constant regardless of the magnitude of force applied to the resistence.
What is an isoinertial muscle action?
Muscle contraction where the muscles are responding to a constant load
What is an isotonic muscle contraction?
A muscle contraction where the length of the muscle changes through a range of motion.
What is isotonic eccentric contraction?
The lengthening of the muscle while tension is developed.
What is a isotonic concentric contraction?
The shortening of a muscle during an effort.
What is the origin?
A fixed attachment point
What is an insertion point?
Moves with the contraction
What is reciprocal inhibition?
Muscles always works pairs, meaning one muscle is contracting whilst the other is relaxing to allow ease of movement
What is the action of an Agonist?
The muscle primarily responsible for producing movement
What is the action of the Antagonist?
The muscle that relaxes as the antagonist contracts to allow ease of movement & minimise the risk of injury
What is the action of the stabiliser?
Muscles the stabilise one part of the body while another part is moving.
What acts as the stabiliser for the spine?
abdominal muscles
What are fascicles?
bundles of muscle fibres.
What are the 5 different muscle shapes in the body?
- circular
- convergent
- parallel
- pennate
- fusiform
What is a pennate muscle fibre?
The fibres are short and attach obliquely to a central tendon that runs the length of the muscle
What is a unipennate muscle fibre?
The fascicles inserts into only one side of the tendon.
What is a bipennate muscle fibre?
The fascicles inserts into the tendon from opposite sides, resembling a feather
What does a multipennate fibre look like?
Looks like a feather side by side.
Do pennate muscles generate amounts of force than fusiform?
Pennate muscles have a greater cross sectional area, meaning they can generate greater force over a longer period of time
How do fusiform muscles differ from pennate?
Fusiform muscles can contract RAPIDLY and develop greater power than pennate fibres
