In this article, I will explain the “ischial bone” in detail.
The ischium bone is a bone under the buttocks and plays an important role in supporting body weight when sitting. It is read as “crackling” and is located at the bottom of the pelvis. I will also explain the characteristics and position of the sciatic bone and its relationship with surrounding muscles and fat. Furthermore, we will touch on sciatic tubercles and explore their structure, position, and relationships with saddle shape, exercise performance, and sciatica. Please use this article to deepen your understanding of the body.

What is the ischium
The ischium bone is an important bone located at the bottom of the pelvis. It is the part that comes into contact with the chair or floor when sitting. This bone plays an important role in buttock muscle and fat acting as a cushion. If you look at the human anatomy diagram, you can see the positional relationships and cooperation along with other bones that make up the pelvis, such as bones such as ilium and pubis.
How to read ischial bone
It is read as “zakotsu.” As you can see from the kanji, “sit” means to sit, “bone” means bone, and when translated literally, it means “bone used when sitting.”
Characteristics of the sciatic bone
The ischium has the function of supporting body weight. It works with the muscles and fat layer of the buttocks to distribute body weight efficiently.
The location and position of the ischial bone

The ischium is located at the bottom of the pelvis, specifically behind the iliac bone and pubic bone. It is the part where weight is applied when sitting, and you will sit on this bone.
How to memorize sciatic bones
Having the image of a “bone that puts weight on when sitting” makes it easier to remember the ischial bone.
English and Latin for sciatic bone
It is called “Ischium” in English, and is similarly expressed as “Ischium” in Latin.
Sciatic bone trivia
The ischial bone not only supports body weight, but is also closely related to the muscles around the buttocks, especially the gluteus maximus muscle. Also, if you sit in the same position for a long time, it is easy to be compressed, which can also cause discomfort and pain. Sitting posture and the use of cushions may help prevent this.
Tissues associated with the sciatic bone: characteristics of ischium tubercles
The ischium tubercle is one of the bones that make up the pelvis, and although its shape varies from person to person, it generally has a prominent shape. Since sciatic tubercles play a role in supporting most of the body weight when sitting, they are made to be very strong. Furthermore, multiple muscles and ligaments are attached to this part, and they play an important role in coordinating body balance and movement.
Tissues related to the sciatic bone: location and location of ischium tubercles
The sciatic tubercle is located in the lower posterior part of the pelvis and is located between the femurs on both sides. Like the other bones that make up the pelvis, ischial tubercles also have a pair of left and right nodes. You can check the location of the sciatic tubercle by sliding the palm of your hand under your buttocks and putting on weight. The hard part you feel when sitting is the ischial tubercle.
Tissues associated with the sciatic bone: trivia about sciatic tubercles
The shape of the saddle used when riding a bicycle or horse is designed based on the location of the ischial tubercle. Therefore, you can get a comfortable ride by taking this into account when choosing a saddle.
Also, ischium tubercles are important bones for runners. When doing exercises such as running, the muscles adhering to the sciatic tubercle move actively, so strengthening this area and improving flexibility will lead to improved performance.
Next is the relationship with sciatica. Sitting too much or sitting incorrectly is known to cause compression around the sciatic tubercle and increase the risk of sciatica. Adequate rest and proper posture are important.
Knowledge about sciatic tubercles can help improve performance in everyday life and sports, and even maintain health. These small bones have a huge impact on our physical movements and health.
