KROK 1 2015 – Question 93 · KROK (Medicine) · Physiology
In a cat with decerebrate rigidity the muscle tone is to be decreased. This can be achieved by:
- A. Destruction of the vestibular nuclei of Deiters
- B. Stimulation of the otolithic vestibular receptors
- C. Stimulation of the vestibular nuclei of Deiters
- D. Stimulation of the vestibulocochlear nerve
- E. Stimulation of the ampullar vestibular receptors
Hint
Think about which brainstem source of excitation to the extensor motoneurons is released from higher inhibition in decerebrate rigidity, and how that drive could be removed.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
