RESPONSES TO NERVE STIMULATION Attach a copy of your experimental recordings showing a period of spontaneous contractions and the response to stimulating the nerves at 20 Hz with both a voltage that produced only a modest response and the voltage that produced the maximal response. 1) Briefly describe the response of the ileum when it is unstimulated and during stimulation of the nerves. It is shown that the rabbit ileum has a constant rate of

Student Exploration: Sight vs. Sound Reactions Vocabulary: histogram‚ mean‚ normal distribution‚ range‚ standard deviation‚ stimulus Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Most professional baseball pitchers can throw a fastball over 145 km/h (90 mph). This gives the batter less than half a second to read the pitch‚ decide whether to swing‚ and then try to hit the ball. No wonder hitting a baseball is considered one of the hardest things to do in sports! 1. What

II-Needle Electromyography: Is complements nerve conduction studies and serves a critical role in the evaluation of both muscle and nerve diseases. Recording the electrical activity of the muscle cell membrane with a needle electrode inserted in the muscle‚ the motor unit potential (MUP) can be recorded. Electromyography is performed using an instrument called electromyograph‚ to produce a record called electromyogram. This represents the summated electrical activity of action potentials of all

the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells. In some cases they have been known to attack the axons themselves. The first known incident of Guillain-Barre syndrome was reported in 1859 by a Frenchman named Jean Baptiste Octave Landry

this would allow a faster healing time for both the limb and the victim with minimal scarring for the tissue and skin. 4. Shortening of a bone: Shortening of the bone will simplify the repair of the nerves and blood vessels which makes it possible for the single suture of an artery‚ vein‚ and/or nerve as necessary. It also allows for the soft tissue on either side of the bone easier to put together. 5. Movements associated with arm‚ forearm‚ wrist‚ and fingers: a. Shoulder: flexion‚ extension

P5 – Physical and psychological theories of ageing Physical changes Hormones and Menopause: When it comes to hormones and menopause Alicia may have had a decrease in the hormone oestrogen which is known to be connected with the osteoporosis. This would have caused Alicia to be at some kind of risk of osteoporosis than others if she had genetically inherited it. However‚ to prevent osteoporosis Alicia could had exercise sessions or any different type of fitness which would have helped her strengthen

Sketch the skeletal muscle cross section. Identify the muscle fibers‚ endomysium and perimysium. Describe what you observed on the slide. Questions A. Why do muscle fibers need to be wrapped and bundled into groups? So that nerves can send a signal to the bundle instead of each individual fiber. Extensions and Flexions are also much more capable because of bundles. B. Which tissue comprises the muscle wrappings? Why?

Recall that Jim’s heart and respiratory rate are increased‚ he was sweating and that his mouth was dry before the raise began. Explain what is happening to his autonomic nervous system (including which division is the most active) and specify exactly how those ANS responses are creating the symptoms noted.
