Types
The primary function of this type is to move bones.
What is Skeletal Muscle?
This attaches bone to muscle.
What are tendons?
We attach to actin molecules and bend inward, pulling the actin filament with us.
What are myosin?
The least efficient way to produce ATP in muscle fibers.
What is creatine phosphate?
What is muscle fatigue?
This tissue forms the walls of hollow structures such as the stomach and blood vessels.
What is smooth muscle?
These are dense bundles of muscle fibers.
What is a fascicle?
I shorten the length of a sarcomere and thus, the entire muscle fiber.
What is an actin?
Without me, the muscle will not relax. Thus, causing rigor mortis.
What is ATP?
This produces the by-product lactic acid and is highly inefficient.
What is anaerobic respiration?
This type of muscle is voluntary.
What is skeletal muscle?
I am also known as a muscle cell.
What is a muscle fiber?
I detach the myosin head from the actin filament.
What is ATP?
This chemical crosses the neuromuscular junction and starts the muscle contraction.
This has occurred when you have a net gain of 36 ATP+CO2 for each glucose molecule.
What is aerobic respiration?
These types of muscles are involuntary.
What are cardiac and smooth muscles?
Consists of bundles of myofibrils.
What is a muscle fiber? or What is a muscle cell?
This concept states that either the fibers contract or they remain relaxed.
What is the "all-or-none" response?
I am the area where actin filaments are anchored.
What is the Z-line?
What is Oxygen?
These types of muscles are striated.
What are skeletal and cardiac muscles?
I am made up of protein fibers called actin (thin) and myosin (thick).
What is a myofibril?
This is determined by the number of muscle fibers that are stimulated.
What is the force of muscle contraction?
The region from one z-line to the next z-line.
What is a sarcomere?
Temporary lack of oxygen availability.
What is oxygen debt?
