How does the motor unit recruitment pattern described in explain the increase in blood lactate which occurs above 50-60% Vo2max? Blood lactate is the buffered form of lactic acid derived from cellular anaerobic glycolysis. (HINT: connect motor unit recruitment order with collective metabolism. And high/low intensity training
My answer so far: The motor unit recruitment pattern described in the lecture materials tells us that when there is low intensity activity (rest to about 50% of Vo2max), minute ventilation (VE) parallels Vo2. We also learn that onset blood lactate accumulation (OBLA) occurs at about 66% Vo2max, and occurs between 50% and 80% Vo2max.

Cortisol binds with this receptor
This type of signal travels through the blood to reach its target cell
This type of signal diffuses through the plasma membrane and activates gene expression
Isoprenaline is a drug that is prescribed for an abnormally low heart rate. It binds with the adrenergic receptors on the pacemaker cells of the heart. This drug would be an __________of the receptor
This hormone is released from the anterior pituitary and binds with receptors in the adrenal cortex
This type of control is how EPI/NE and ACh control heart rate
A non-steroid hormone might cause one of these to open
Epinephrine and norepinephrine bind with this type of receptor
Insulin is the _____________ of the insulin receptor
This type of signal influences the same cell that released it
This hormone is released from the posterior pituitary gland and causes conservation of water
The binding of cortisol with a glucocorticoid receptor on the hypothalamus, reducing the secretion of corticotropin releasing hormone is an example of this process.
The normal action of EPI/NE is to increase heart rate. Propranalol is a drug that slows heart rate by binding to beta-adrenergic receptors. This type of drug is an______ of the receptor
This type of control is how EPI/NE control blood vessel diameter
This gland releases oxyticin and antidiuretic hormone
This type of signal diffuses through some interstitial fluid before binding with its receptor

You are the R.N caring for a 65-year-old woman admitted last evening with a recent history of cellulitis and a 3-day history of persistent vomiting and diarrhea. She takes no medications at home, other than a daily multivitamin. Her weight on admission was 153 pounds. The patient states her original weight is 165 pounds (75 kg). The nurse notes that the patient’s mucous membranes and skin are dry. Vital signs are temperature 99.8° F, pulse 112, respirations 32, and blood pressure 100/76. Her urine output over the last 8 hours is 125 mL. Labs reveal the following:

K+ 3.5 mEq/L |
Hematocrit 53% |
Urine specific gravity 1.033 |

Multiple Choice
1. You have a lamb that has just suffered a laceration and is bleeding. From a physiological standpoint, what needs to happen to stop the bleeding?
a. Apotransferrin and Transferrin protein are activated and platelets form the plug
b. Constriction of the injured vessel, Formation of platelet plug to occlude the opening and clot formation
c. Constriction of the injured vessel recruitment of eosinophils, basophils and neutrophils and clot formation
d. Formation of platelet plug, inflammation and increase in the Erythrocyte cells
2. Cats have better nocturnal vision because:
a. The depth perception is greater due to the medial location of the eyes
b. The convex lens and the pupil have a greater range of dilation
