| Excitation | Contraction | Factors Affecting Force Production |
|---|---|---|
|
What is DHP Receptor?
The voltage-sensitive protein that is directly adjacent to T-tubules
|
What is troponin?
The protein that binds to calcium on the actin filament.
|
What are slow oxidative fibres?
This muscle fibre is the most fatigue resistant.
|
|
What is Sarcoplasmic Reticulum?
The network which stores calcium inside a muscle fibre
|
What are calcium ions?
This ion acts as the cross bridge cycling regulator
|
What is muscle length?
This factor affects force production because it determines the number of cross bridges that can be formed.
|
|
What is Nicotine?
The molecule, aside from acetylcholine, that can also stimulate nicotinic receptors
|
What role does the second ATP molecule play (after power stroke)?
The muscle cannot relax without this.
|
What is maximum tetanic force?
This force is 3-5x stronger than maximum twitch force.
