In a spider, the Pedicel separates the cephalothorax from the abdomen.
Diaphragm
In humans and other mammals the thorax and abdomen are separated by a sheet of muscle called the diaphragm. In insects like wasps and bees where there is a narrow region between the thorax and the abdomen this is called the petiole.
In the body, the diaphragm is a curved sheet of smooth muscle which separates the thorax from the abdomen. When it contracts, the diaphragm flattens, which INCREASES the volume of the THORAX, which then EXPANDS the lungs. Contracting the diaphragm therefore is associated with breathing IN, NOT OUT. In Birth Control, a diaphragm keeps sperm from getting to your cervix and uterus and making you pregnant.

You have the sheet of muscles that protects the abdomen. They are there in front of the abdominal cavity, in the side and the back side also. The six pack muscle, called as rectus abdominis, is the prominent example of the abdominal muscle in the front. Then you have the the external oblique, internal oblique and the transversus abdominis muscles. They are there in the side of the abdomen. You have the sheet like aponeurosis of these muscles in the front of the abdomen. The position of the rectus abdominis, in relation of the aponeurosis of the above muscles, is very interesting.
weakness of the diaphragm, the sheet of muscles at the top of the abdomen that perform the main work of breathing and coughing. Diaphragm weakness leads to reduced energy and stamina, and increased lung infection
These would be the abdominal muscles.

Tendons are the thin sheet of muscles that connect to the bones and joints. The main muscles are attached to the tendons to give our body its form.
