Dissection Review
Many human musculuss are modified from those of the hog ( or any four-footed ) as a consequence of the demands of an unsloped position. The undermentioned inquiries refer to these differences. 1. How does the human cowl muscle musculus differ from the pig’s? Worlds have one individual cowl muscle musculus. the hog has three separate musculuss.

They are the clavotrapezius. the acromiotrapezius. and the spinotrapezius.

2. How does the deltoid differ?
In the human it is thick and heavy but the hogs is a thin set.

3. How does the extent and orientation of the human sartorious musculus differ
from its comparative place in the hog? The human satorius is thin strap like musculus that runs sidelong across the anterior thigh. The pigs level. and covers most of the anterolateral thigh.

4. Explain the differences in footings of differences in map. The hog sartorius acts to adduct the thigh and flex the hip. The human sartorius produces flexure at the articulatio genus and sidelong rotary motion of the hip.

5. The human rectus abdominis is decidedly divided by four transverse sinews ( sinewy intersections ) . These sinews are absent or hard to place in the hog. How make these sinews affect the human unsloped position? These sinews support the abdominal muscular wall so that the entrails are non allowed to go cernuous in the unsloped position of worlds.
