spinal cord‚ and the nerves. The nervous system enables a way for the brain to receive information about someone’s surrounding. Then‚ the brain is able to send signals to various areas of the body‚ so it can respond. Millions and millions of cells called neurons creates the nervous system. “Specialized neurons called receptors are located in the ears and eyes and the other sense organs of the body. The receptors translate events in a person’s surroundings . . . into nerve messages‚ which are known

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

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

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?

Through this‚ we can delve deeper by understanding how nerves‚ through the actions Of various neurotransmitters affect the motility of the gastrointesital tract. Furthermore‚ we can investigate The effects of drugs‚ and their uses in replicating effects of autonomic neurotransmitters as well as The way certain drugs can interfere with autonomic neurotransmitters and how they interact with Their target tissues.

No summation 9. Why is it important that summation not occur in heart muscle? Summation would increase the Heart muscle contractions which would lead to heart attack. Activity 2: Vagus Nerve Stimulation 1. Describe the effect of the vagus nerve stimulation on the heartbeat. The vagus nerve stimulation caused the heartbeat to flatline and then restart and react normally 2. Soon after you applied the stimuli‚ did the heart rate increase or decrease? Soon after the stimulation is
