**Quiz: Identifying False Statements about the Muscle Spindle****Question:**Which statement is false?**Options:**1. ◯ The muscle spindle forms a monosynaptic connection with the alpha motor neuron for antagonistic muscle group.2. ◯ The muscle spindle synapses directly on the alpha motor neuron for muscle fiber it innervates.3. ◯ The muscle spindle innervates intrafusal fibers of the muscle.4. ◯ The muscle spindle has myelinated axons.**Explanation:**- **Option 1:** The muscle spindle forms a monosynaptic connection with the alpha motor neuron primarily for the muscle fiber it innervates, not the antagonistic muscle group.- **Option 2:** Correct - The muscle spindle indeed synapses directly on the alpha motor neuron for the muscle fiber it innervates.- **Option 3:** Correct - The muscle spindle does innervate the intrafusal fibers of the muscle, which are specialized sensory organs within the muscle.- **Option 4:** Correct - The muscle spindle has myelinated axons, which help in the rapid transmission of sensory information to the central nervous system.Note: Participants need to select the statement that is false to check their understanding of the muscle spindle’s anatomy and physiology.

Skeletal muscle is described as striated. What are the lighter, thinner stripes noted under the microscope? Group of answer choices troponin actin myosin dystrophin Rather than innervating individual muscle fibers, motor neurons often innervate two or more muscle fibers. The motor neuron and the muscle fibers it innervates are together called a: Group of answer choices motor unit myofibril muscle fascicle motor fascia Fast glycolytic muscle fibers allow for relatively quick ATP energy production by splitting glucose (but eventually leads to fatigue), a process described as: Group of answer choices fermentation aerobic pathway anaerobic pathway ATP reserve use
Why does muscle CAP Amp for both the normal Ringer's solution and Ringer's solution with Neostigmine increased as the stimulus amplitude increased, but a normal Ringer's solution would have a larger muscle CAP Amp value? Why is this the same case for a CAP Period as stimulus amplitude increases?. Why would Muscle CAP Period values for Ringer's with NEO then have larger values. Why does a normal Ringer's solution take longer to reach maximum action potential ?
The greater the influx of calcium into the presynaptic axon terminal, the greater the O magnitude of inhibition. release of neurotransmitter. O amplitude of the action potential O rate of reuptake by an enzyme
You cut the axon of a single motor neuron innervating the biceps muscle. Which of the following is true? a. The biceps muscle will no longer be able to contractb. Only one muscle fiber in the biceps will be unable to contractc. All muscle fibers in the biceps innervated by that motor neuron will no longer be able to contractd. There will be no effect since each muscle fiber is innervated by multiple motor neurons
