Terms and structure
Three types of muscle tissue
What are cardiac, smooth and skeletal
A repeating unit of myofibril
What is a sarcomere?
The brain sends it to start the process of muscle movement.
What is an action potential or a signal?
What is a motor unit?
The molecule that stores energy
What is ATP?
Involuntary muscle
What are cardiac and smooth?
The organelle that releases calcium to start a contraction.
What is the sarcoplasmic reticulum?
The interface between the neuron and another cell.
What is a synapse or neuromuscular junction?
An individual muscle fiber contracts maximally in response to an action potential.
What is the all or none law of muscle contraction?
The most efficient way that ATP is generated.
What is aerobic respiration?
The type of muscle cell that has multiple nuclei
What is skeletal?
The thing to which calcium attaches.
What is troponin?
The neurotransmitter that initiates an action potential in the post synaptic membrane.
What is acetylcholine?
A stimulus that is strong enough to create action potentials on all motor neurons to a particular muscle
What is maximal stimulus?
The chemical stored in muscle as a second source of making ATP.
What is creatine phosphate?
Four functional characteristics of muscle.
What are contractility, excitability, estensibility and elasticity?
This is what it is called when the myosin head move to contract.
What is a power stroke?
The chemical that inactivates the neurotransmitter.
What is acetylcholinesterase?
When a muscle fiber actually receives a signal and contracts.
What is to recruit?
The least efficient way to produce ATP in the muscles.
What is anaerobic respiration?
The layer of collagen around one fascicle.
What is perimysium?
The thing that breaks the bond to allow return stroke.
What is ATP?
The mechanism by which Calcium is transported back into the Sarcoplasmic reticulum.
What is active transport?
A stimulus strong enough to create one action potential in a neuron.
What is threshold stimulus?
The by product of the process of the production of ATP when there is no oxygen available.
What is lactic acid?
