While it definitely slowed, the contractions were sporadic at best. The heart lost its regularity and showed random contraction intervals, some ranging shorter than normal while others had greater time gaps between contractions. Procedure 5: Effects of a Ligature on the Heart After the knot had been tied around the AV groove, no noticeable alterations were noticed to heart contraction. Upon tightening of the thread however, the heart appeared in clear distress. Beat irregularities ensued…
is to create functional synaptic connections. Synapse formation involves organized cell morphological and structural modifications that are carried out through ligand-receptor interactions, intracellular signaling cascades, and complex filamentous actin remodeling. Studies have revealed that axon guidance molecules play an important role in regulating synapse formation. These signaling molecules are able to determine synaptic sites and regulate the pre-or post-synaptic differentiations…
ANEQ 305 Muscles in Racehorses There are many ways in which researchers can examine muscles of thoroughbred racehorses. They can look at the amount of, and different types of muscle fibers found in thoroughbreds, the muscles ability to adapt to high intensive exercise, the effects from changing the inclination the horse is exercising on, and if age and gender affect the way the muscles react. The thoroughbred horse stems back to a founder stallion that makes up 95% paternal and 9 to 10…

QUESTIONS 1. Discuss the pathophysiology of coronary artery atherosclerosis. Include discussion of risk factors associated with the development of this disease. (10 points) Coronary artery atherosclerosis is most commonly comprised of atherosclerotic fibrous fatty obstructions of the large epicardial vessels, which provide for blood flow and transport nutrients, oxygen, and elimination of metabolic waste products such as CO2, lactic acid, and hydrogen ions. Coronary artery atherosclerosis…
