Define 2nd Cross-bridge attachment and give an example of how Cross-bridge attachment and 2nd Cross-bridge attachment are alike if in any way.
What is Cross-bridge attachment being the order for muscles to contract again, ATP is once again broken down and calcium is once again bond to troponin.
300
In what ways are Abductor and Adductor different?
What is Abductor means to move away from midline and Adductor meaning to move toward the body.
300
Explain how flexion and extension are alike and different.
What is both dealing with a joint. Flexion is a movement that will decrease the angle of the joint. Extension is to increase the angle of the joint.

Give the appropriate name for the large chest muscle.
What is pectoralis major.
400
Give some characteristics of Rigor Mortis (also known as Stiff Death).
What is usually occurs within a few hours after death, some calcium present bound to troponin, causing myosin heads to stay attached to active sites. Lysosomes will eventually digest myofibrils, causing heads to detach.
400
The terms Major, Maximus, Minor, and Minimus all have something in common, tell what and define each.

400
Define Myofibrils, tell how large or small the layer is and how superficial or deep it is.
What is myofibrils being the smallest fiber of muscle, contains actin and myosin filaments, the contractile units are called sacromeres.
400
Name all muscles labeled in the lower leg.
What is the peroneus longus, tibialis anterior, extension digitorum longus, permoneus brevis.
500
Explain Muscle Fatigue in three parts.
What is nerve stimulation still occurs even when ATP and calcium sources are depleted. Inadequate oxygen supply= anaerobic glycolysis it results in pyruvic acid and H ions accumulating in the miscle tissue and causes cramping. Lactic Avid is also broken down within the hour, they become C02,H20, glucose or storage as glycogen.
500
Give three terms that indicate direction to horizontal axis and define.

Define each of the muscle terms: origin, insertion, and action.
What is origin: place were muscle is located.
Insertion: place were the muscle attaches.
Action:the function the muscle provides.
