An animal has an increased tonus of extensor muscles. This the result of intensified information transmission to the motoneurons of the spinal cord through the following descending pathways:
- A. Vestibulospinal
- B. Lateral corticospinal
- C. Reticulospinal
- D. Rubrospinal
- E. Medial corticospinal
Hint
Separate the descending tracts into those that excite antigravity extensor motoneurons and those that favour flexors or voluntary movement.
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.
