Blood Supply to the Forelimb of the Dog

From a channel Lumen includes in full: The channel is run by an associate professor of veterinary anatomy, and every sampled transcript is a systematic anatomy lecture or real dissection that names structures with their origins, insertions, branches and functions, with no entertainment hooks. Titles are plain and descriptive (e.g. 'Sheep Heart Anatomy Explained (Part 1) | Chambers and External Features'), with no clickbait, promos or vlogs in the sample. This is exactly the procedure and dissection teaching content the owner wants, aimed at veterinary students.

A 14-minute video from Veterinary Anatomy's catalogue; the title names its topic.
