Terms
The two filaments that work together to produce a muscle contraction
What are actin and myosin?
This attaches muscle to bones
What are tendons?
This type of muscle is non-striated.
What is Smooth?
The amount of ATP used in each myosin/actin cross-bridge cycle
What is 1?
This covers the end of bones to make a smooth movement (you saw this on the chicken wing dissection)
What is articular cartilage?
This term means "to respond to a stimulus from a motor neuron or hormone"
What is Excitability?
This is the term for the middle of a muscle
What is belly?
This is the name of the model of actin and myosin touching and moving past one another.
What is sliding filament model of muscle contraction?
This separates one sarcomere from another
What is the Z-line?
What is insertion?
This term means "to shorten when stimulated"
This membrane covers an individual muscle fiber
What is endomysium?
This is the outer membrane found around the belly of a muscle
What is epimysium?
During a workout, if you lack this, it can cause your muscles to burn.

The point of attachment on the more stationary bone is called this
What is Origin?
This term means "the ability to recoil or bounce back to the original shape"
What is Elasticity
Tissue surrounding a fascicle
What is perimysium?
This happens to the protein when stuff binds and unbinds to protein
What is change shape?
This is when a myosin head attaches to the myosin, pulling the actin filament toward the M line.
What is Prime Mover?
These are the 4 functions of the muscular system
What are Produces Movement, Maintains Posture, Stabilizes Joints, and Generates Heat
This covers each muscle fiber and conducts impulses
What is Sarcoplasmic Reticulum?
This binds to troponin exposing the active sites.
What is calcium?
These two structures block the active site on an actin filament
What are troponin and tropomysoin?
This term describes the opposing muscle during motion (relaxing)
