The submandibular lymph nodes (submaxillary glands in older texts), three to six in number, are placed beneath the body of the mandible in the submandibular triangle, and rest on the superficial surface of the submandibular gland.

One gland, the middle gland of Stahr, which lies on the facial artery as it turns over the mandible, is the most constant of the series; small lymph glands are sometimes found on the deep surface of the submandibular gland.

The afferents of the submandibular glands drain the medial canthus, the cheek, the side of the nose, the upper lip, the lateral part of the lower lip, the gums, and the anterior part of the margin of the tongue.

Efferent lymph vessels from the facial and submental lymph nodes also enter the submandibular glands. Their efferent vessels pass to the superior deep cervical lymph nodes.

gollark: Honestly that's entirely unnecessary and I would probably only need simple splitting into lines and label handling, but you know.

gollark: That's how you would do it in my thing, using a somewhat insane S-expression assembly-ish language.

gollark: Using hypothetical assembly syntax I haven't actually implemented:```# start of memory to add kittens to(add r1 r0 0x1000) # maybe there would be nice dedicated syntax for "set register" actually# end of kittenized region(add r2 r0 0x1600)(label loop (add r3 r0 40) (poke r3 r1 0) (add r3 r0 94) (poke r3 r1 1) # and so on (add r1 r1 8) (jlt r1 r2 loop))```

gollark: To create RAM kittens, all you need to do is `ADD` the ASCII value of each character into a temporary register, `POKE` them into the right memory location (using the per-instruction `POKE` offset, probably), and then do that in a loop.

gollark: I should probably implement arithmetic instructions then a basic assembler, I guess, because hand-writing machine code is unpleasant.
