0:00:04.817,0:00:06.627
Salut tout le monde, c'est Sinix.

0:00:06.631,0:00:10.044
C'est l'heure d'un nouvel épisode [br]des techniques rapides en anatomie.

0:00:10.056,0:00:13.510
Une série qui vous donnera [br]des astuces pratiques

0:00:13.510,0:00:15.488
et qui vous aidera à vous sentir[br]plus à l'aise avec

0:00:15.488,0:00:17.681
le fait de dessiner des personnages [br]avec votre imagination.

0:00:17.687,0:00:20.395
Aujourd'hui, nous parlerons des bras

0:00:20.395,0:00:22.934
également, ne paniquez pas mais

0:00:22.934,0:00:27.018
mais cet vidéo sur les bras [br]nous rapproche de la fin de la série,

0:00:27.018,0:00:29.457
il ne nous reste que deux vidéos.

0:00:29.457,0:00:34.050
Quoi qu'il en soit, [br]concentrons-nous pour l'instant [br]sur ces membres supérieurs.

0:00:34.276,0:00:37.831
ça ne sera sûrement pas la partie [br]la plus amusante de la série ou quoi,

0:00:37.831,0:00:40.288
mais ça sera la plus plus drôle

0:00:40.288,0:00:43.485
donc remontez vos manches [br]et mettez vous au travail.

0:00:43.485,0:00:45.224
On commence avec la structure,

0:00:45.224,0:00:48.715
Nous avons déjà abordé [br]les deux épaules et les mains

0:00:48.715,0:00:49.600
dans d'autres vidéos,

0:00:49.601,0:00:53.355
Donc on s'assure juste de pouvoir [br]associer les deux ensembles

0:00:53.355,0:00:58.506
Je fais un croquis rapide des vues de face, [br]de côté et de dos d'une épaule pour commencer.

0:00:58.506,0:01:01.367
Voir une épaule et un buste sans bras

0:01:01.367,0:01:04.245
me fait toujours penser à un petit [br]agneau ou un truc du genre...

0:01:04.245,0:01:06.783
mais quoi qu'il en soit, [br]on va se concentrer sur

0:01:06.783,0:01:09.628
l'analyse du squelette du bras en premier.

0:01:09.628,0:01:12.377
Bien, sûr nous avons un seul os principal

0:01:12.377,0:01:13.562
dans le bras supérieur

0:01:13.562,0:01:15.425
et deux dans l'avant bras,

0:01:15.425,0:01:16.983
reliés au niveau du coude.

0:01:16.983,0:01:21.318
Mais qaund je dessine ça, la première [br]chose que je veux mettre en avant

0:01:21.318,0:01:24.090
c'est que les choses ne sont pas [br]dans une ligne parfaitement droite.

0:01:24.090,0:01:26.138
Vous pouvez même prendre un moment

0:01:26.138,0:01:27.737
et essayer de regarder par vous-même

0:01:27.737,0:01:30.233
il suffit de tendre votre bras tout droit

0:01:30.233,0:01:32.341
et de fermer votre œil opposé.

0:01:32.341,0:01:35.582
Maintenant, faites de votre mieux [br]pour regarder droit devant vous

0:01:35.582,0:01:37.789
le canon de cette arme [br]massive que vous appelez

0:01:37.789,0:01:38.967
votre bras supérieur.

0:01:38.967,0:01:42.186
si vous alignez votre vision [br]de votre épaule avec votre coude

0:01:42.186,0:01:44.687
vous remarquerez que votre avant-bras ne s'aligne

0:01:44.687,0:01:47.018
pas vraiment comme vous l'aurez pensé.

0:01:47.018,0:01:51.181
Pour devenir vraiment bon dans le dessin [br]de toutes formes organiques,

0:01:51.181,0:01:55.776
il est important d'essayer d'identifier [br]ces types de décalages subtils.

0:01:55.776,0:01:57.733
autant que possible.

0:01:57.733,0:01:59.833
Bref, revenons-en à ces os.

0:01:59.833,0:02:01.843
L'humérus est évidemment l'os

0:02:01.843,0:02:03.216
du bras supérieur,

0:02:03.216,0:02:05.982
pendant ce temps, l'avant-bras [br]possède le cubitus,

0:02:05.982,0:02:08.989
que je considérerais comme [br]l'os principal de l'avant-bras.

0:02:08.989,0:02:11.498
C'est celui avec lequel vous frapperiez quelqu'un

0:02:11.498,0:02:12.564
après lui avoir mis un coup de coude.

0:02:12.609,0:02:15.548
Ensuite le radius, qui provient

0:02:15.548,0:02:17.933
de la partie extérieur du coude

0:02:17.933,0:02:20.806
autrement dit, la partie [br]la plus éloignée de votre corps

0:02:20.806,0:02:24.544
et toujours connecté du [br]côté des pouces de votre main.

0:02:24.817,0:02:27.799
Ainsi, nous pouvons effectuer [br]un léger mouvement de torsion

0:02:27.799,0:02:29.303
autour de l'avant bras.

0:02:29.303,0:02:30.761
D'où le nom "radius"

0:02:30.814,0:02:33.336
Le dernier élément squelettique [br]que je veux mentionner

0:02:33.336,0:02:34.602
est le nerf du coude.

0:02:34.798,0:02:37.543
Qui est juste une extension de l'humérus

0:02:37.543,0:02:40.465
qui fait saillie du côté intérieur du coude

0:02:40.465,0:02:41.981
proche du corps.

0:02:42.081,0:02:43.390
On l'appelle le nerf du coude

0:02:43.390,0:02:46.047
en raison d'une terminaison nerveuse[br]exposée à côté

0:02:46.047,0:02:48.293
qui envoie une décharge dans votre bras

0:02:48.293,0:02:50.860
si vous vous cognez contre quelque chose.

0:02:50.900,0:02:53.158
Alors, si jamais vous avez [br]l'occasion de donner un coup

0:02:53.158,0:02:55.882
de crayon ou de stylet [br]au nerf du coude de votre ami

0:02:55.882,0:02:57.636
fais attention au choc, [br]c'est de la comédie gratuite.

0:02:57.636,0:03:00.987
Très bien , j'ai ajouté [br]des mains à ce dessin,

0:03:00.987,0:03:03.532
et je sais que ce n'est pas une vidéo sur les mains

0:03:03.532,0:03:07.556
mais puisque les poignets et les [br]décalages organiques sont si importants,

0:03:07.556,0:03:11.067
Jetons tout de même un coup [br]d'œil rapide à cette connexion.

0:03:11.140,0:03:13.027
Gardez à l'esprit qu'au moment

0:03:13.027,0:03:15.083
ou le radius et le cubitus arrivent au poignet

0:03:15.083,0:03:17.269
