Passive and active properties of mammalian intrafusal fibres
The properties of individual intrafusal muscle fibres were studied in isolated cat tail spindles, decapsulated in the equatorial region. Structures were visualized using differential interference contrast microscopy. Stretch could be applied to both ends of the spindle. High impedance micropipettes (K citrate-filled) were used to impale individual fibres for voltage recording or current passage.
