Danielle Rollins Cardiovascular Physiology Activity 1 1) Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action

Fracture will not allow full ROM Difference between ulnar collateral ligament and radial collateral ligament? The ulnar collateral ligament is in a triangular shape and is stronger Annular ligament provides lateral and superior stability Damage to brachial artery & nerve leads to volksman flexion fracture‚ which ultimately leads to open hand Which is the strongest elbow flexor? Brachialis Brachialradialis Functional when elbow flexes against resistance or rapidly. Acting alone this muscle would

Effect of Exercise on Pulse Rate and Blood Pressure Purpose: To determine the effect of jogging on pulse rate and blood pressure. Hypothesis: If you jog then your heart rate and blood pressure will increase. Materials: Tape Measure Blood Pressure Cuff Procedure: 1. Record resting blood pressure and heart rate. 2. Measure out 100m. 3. Jog 100m (same speed every time) 4. When finished jogging 100m record heart rate and blood pressure. 5. Repeat steps 3&4‚ 3 more times 6. Calculate average

Physiology‚ Berry HOMEOSTASIS LAB ACTIVITY Introduction: Homeostasis means maintaining a relatively constant state of the body’s internal environment. The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback. When a stimulus (environment change) is met by a response that reverses (negates) the trend of the stimulus‚ it is negative feedback. As a result the internal environment is returned to normal. Pulse rate is constantly checked

Kenya Henderson KINS 2100 Due: 4/3/12 Case Study: Knee Injury This case study focuses on a male who suffered a knee injury form skiing‚ which in turn resulted in weakness in his foot. With the help of MR Neurography the doctor was able to accurately diagnose the patient and provide a successful outcome. The gentleman suffered an injury to his left knee while snow skiing. He fell onto his leg with an immediate disruption of the knee and instant onset of foot weakness. There was considerable

Variables Affecting Human Arterial Pressure and Pulse Rate BIOL-204 Introduction: The woozy feeling when standing up too quickly. After going for a run‚ feeling as if one more beat and the heart would project itself out of the chest. Or quite the opposite and being in a very relaxed state. These are all changes one experiences at some time or another. What causes the different feelings and how each variable affects pulse rate and blood pressure has many wondering. Because of this curiosity

If they were ripped and torn‚ the reattachment would be extremely difficult. 4) The doctor had to trim the bone on each side of the
