| Frage | Antworten |
| How does the firing rate differ between nuclear bag fibers and nuclear chain fibers? | A bag fiber will have elevated firing rate when the muscle is moving and will go back to normal when it stops moving. A chain fiber will have elevated firing rate while the muscle is stretched and remain elevated the whole time it is stretched. |
| What is the purpose of the fusimotor system? | It keeps the muscle spindle tout allowing it to still sense movements when the muscle changes length. It also effects the sensitivity of the muscle spindle. |
| What nerve fiber is connected to the Golgi tendon organ? | Type Ib |
| What type of tension can the golgi tendon organ sense? | Active muscle tension. |
| What do joint receptors detect. What is the problem with them? | Changes of joint angle. They are not very sensitive to changes in joint angle. |
| What is proprioception? | Our innate ability to detect where our limbs are without visual information. |
| What does proprioception detect? What does kinesthesia detect? | Proprioception detects the actual position of the limb while kinesthesia allows the detection of limb movement. this is much easier than proprioception. |
| Give the three types of mechanoreceptors. | Muscle spindles, Golgi-tendon organs and Joint receptors |
| Where are muscles spindles found? | Fleshy part of the muscle. |
| Give the two types of muscle spindle, are they high or low in numbers, what does each of them detect? | Nuclear bag fibers - detect muscle movement, low numbers. Nuclear chain fibers, detect muscle length, high numbers. |
| Where is the primary ending found? what nerve type is attaches to this part of the muscle spindle? | In the middle, its attached to type Ia |
| What nerve attaches to secondary endings of a nerve fiber? | Type IIa |
