How well did the results compare with your prediction? Your answer:A collapsed lung pneumothorax is a buildup of air in the space between the lung and the chest wall pleural space. Name each phase of a typical muscle twitch, and, on the following line, describe what is happening in each phase. Surface tension was sequentially decreased. Read lab exercise 29a do activities 3. How well did the results compare with your prediction? Despite themedication allowing for greater air movement the patient is asthemic because the lateral value will never reach normal. Submit this completed document by the assignment due date found in the Syllabus. To explain the differences between tidal volume, inspiratory reserve volume, expiratory reserve volume, vital capacity, residual volume, total lung capacity, forced vital capacity, forced expiratory….
How well did the results compare with your prediction? Because there is still excess air. It increased for the emphysema patient and decreased for the asthma patient. Organization of the Somatic Nervous. Compare the breathing rates during normal breathing, moderate moderate exercise, and heavy exercise. Many fascicles are bound together to make a muscle Motor unit-A motor unit consists of a motor neuron and all of the muscle fibers in innervates. During heavy exercise, further changes in respiration are required to meet the extreme metabolic demands of the body. No all of the values did not return normal.
This phase is the period of time prior to muscle contractions, however chemical changes in the cells occur in preparation for muscle contractions. What lung values changed from those of the normal patient in the spirogram when the patient with emphysema was selected? D-It increased for both patients 1. Inhaler medications for an asthma patient patient are designed to You correctly answered: b. Asthma and Chronic Bronchitis are examples of obstructive disorders. Airway resistance is also increased as the lung tissue becomes more flimsy and exerts less anchoring on the surrounding airways. It increased for both patients. It remained unchanged for both patients.
Air flowsfrom the lungs causing the collapse of the lung. End plate potential is caused by the events that occur at the neuromuscular junction. During a single twitch of a skeletal muscle You correctly answered: b. C body temperature Activity 4 Explain the difference in activity between tubes 1 and 2. Activity 1 What do tubes 2, 6, and 7 reveal about pH and amylase activity? In resting skeletal muscle, calcium is stored in c.
Rename this document to include your first and last name prior to submitting, e. Why do you think some values did not return all the way to normal? Why did these values change as they did? According to Cozby 2009 inferential statistics are used to determine whether we can in fact make statements that the results reflect what would happen if we were to conduct the experiment again and again with multiple samples Define probability and discuss how…. What emergency procedure would be used to achieve this result if these were the lungs in a living person? Activity 5 While swallowing a mouthful of water from a paper cup, consciously note the movement of your tongue during the process. Electrical stimulus- used to mimic the contractions of skeletal muscles Latent period-Latent period is the period of time between the generation of an action potential in a muscle cell and the start of muscle contraction. Medication is atomized, allowing for direct application onto afflicted airways. Give one possible explanation for this. During the latent phase there is no muscle contraction.
Relaxation- muscle is shortened, returns to zero and back initial length. The lungs did not re-inflate. Exercise 2: Skeletal Muscle Physiology: Activity 1: The Muscle Twitch and the Latent Period Lab Report Pre- lab Quiz Results You scored 20% by answering 1 out of 5 questions correctly. Explain your answer, based on what you know about the substrate of peptidase. Freezing had no affect How does the effect of freezing differ from the affect of boiling? More blood in the glomeruli means more work, so the job has to be done faster.
How is this change in whole-muscle force achieved in vivo? What do these movements accomplish? PhysioEx allows students to repeat labs as often as they like, perform experiments without harming live animals, and conduct experiments that are difficult to perform in a wet lab environment because of time, cost, or safety concerns. Activity 3 Which pH provided the highest pepsin activity? What happened to the left side of the bell jar when the valve was opened? My results went well with my prediction because I predicted that B fiber would react slower. Skeletal muscles are connected to bones by Your answer : c. During the latent period for an isometric contraction c. What lung values will change from those of the normal patient in the spirogram when the patient with emphysema is selected select all that apply? Your answer:It caused the lung to collapse because the pressure in the pleural cavity is less than the intrapulmonary pressure. What would you need to do to make the left lung function properly again? Tutorial, and online worksheets with multiple-choice answers. A restrictive disorder is one that may affect the lung tissue itself or the capacity of the lungs to expand and hold predicted volumes of air.
Sensory neurons respond to an appropriate sensory stimulus with a change in membrane potential that is You correctly answered: b. Describe the effect that the inhaler medication had on the asthmatic patient. Go to the PhysioEx 7. The motor neuron and muscle fiber intersect at what is called Your answer : b. It decreased for both patients.
