- Abstract
- Isolated inferior oblique muscles (I0) of rabbits were stimulated directly in vitro at 20, 25, 30 and 35° C to produce fused tetanic contractions, and they were released at various controlled velocities. At body temperature the maximum shortening velocity (Vo) of Io was 19.1 ± 2.0 muscle length per s (mean ± SE) corresponding to a maximum shortening velocity of the sarcomere of 57.3 ± 6.0 µm s 1, corresponding to an eye angular velocity of 850° per s and this figure is of the same order of magnitude as the fastest saccadic eye movement (600° per s). These data are similar in EOM of rats.
