This video is one of around 310 titles, originally broadcast on Channel 7 of the ILEA closed-circuit television network, given to Wellcome Trust from the University of London Audio-Visual Centre shortly after it closed in the late 1980s. Although some of these programmes might now seem rather out-dated, they probably represent the largest and most diversified body of medical video produced in any British university at this time, and give a comprehensive and fascinating view of the state of medical and surgical research and practice in the 1970s and early 1980s, thus constituting a contemporary medical-historical archive of great interest. The lectures take place in a small and intimate studio setting, often face-to-face with the camera - testing the lecturers' abilities to integrate visual aids within reach. Some of the lecturers are telegenic and some are clearly uncomfortable with this medium.

Segment 1 Gilliland introduces Huxley. Huxley begins the lecture by describing in detail the anatomy of a muscle. Time start: 00:00:00:00 Time end: 00:04:44:00 Length: 00:04:44:00

Segment 2 Huxley describes the appearance of muscle fibres, using photomicrographs to illustrate his points. Time start: 00:04:44:00 Time end: 00:09:32:13 Length: 00:04:48:13

Segment 3 Huxley shows the first part of a short film which shows muscle striation patterns during contraction. Time start: 00:09:32:13 Time end: 00:15:04:13 Length: 00:05:32:13

Segment 4 Huxley shows diagrams which further illustrate the areas covered by the film. Then he shows the film again, with reference to specific sections. Time start: 00:15:04:13 Time end: 00:20:15:00 Length: 00:05:10:12

Segment 5 Huxley shows the second part of the short film, this time looking at the maximum length for muscle contraction. Time start: 00:20:15:00 Time end: 00:26:05:10 Length: 00:05:50:10

Segment 6 Huxley describes, using diagrams, the sliding movements that happen between filaments in muscle fibres. Time start: 00:26:05:10 Time end: 00:30:22:00 Length: 00:04:16:15

Segment 7 Huxley shows diagrams which detail striation patterns in muscle contractions. Time start: 00:30:22:00 Time end: 00:35:15:00 Length: 00:04:53:00

Segment 8 Huxley sums up and concludes the lecture. Time start: 00:35:15:00 Time end: 00:39:20:19 Length: 00:04:05:19
