Muscle Structure
The structure of the muscle represented by the entire twizzler during the twizzer analogy.
What is a bundle of muscle fibers?
The muscle-type that tires the quickest.
What is Skeletal Muscle?
The signal the brain sends out at the start of muscle contraction.
The organ that initiates muscle contraction.
What is the brain?
A group of cells that are similar in structure and function.
What are tissues?
The name for cells that make up muscles.
The muscle type that tires the slowest.
What is Cardiac Muscle?
The structure the action potential moves through once the brain sends the signal.
What is a nerve or neuron?
The places along actin where myosin heads can connect.
What are binding sites?
The tissue that connects bones to muscles.
What are tendons?
The thin protein in muscle cells.
What is actin?
The muscle type that is both voluntary and involuntary.
What is Smoothe Muscle?
The place where the nerve meets the muscle.
What is the neuromuscular junction?
The thing created when a myosin head attaches to a binding site.
What is a cross-bridge?
The muscle type that helps you digest.
What is smooth muscle?
The repeating pattern created by actin and myosin.
What are sarcomeres?
The muscle type that is not striated.
The space between the nerve and the muscle at the neuromuscular junction.
The structure that Calcium goes into in order to open the binding sites on actin.
The elongated strands inside muscle fibers that consist of actin and myosin.
What are myofibrils?
The only muscle type that is multinucleated
The strand around the actin that blocks the binding sites when Calcium is not present.
What is tropomyosin?
The energy that powers muscle contraction AND the process by which we generate that energy.
What are ATP and cellular respiration?
The four muscle tissue functions.
What are moves internal and external body parts, maintains structure/balance, stabilizes joints, and generates heat?
