Buttocks intramuscular injection

■  The skin texture is real, and the injection marks are not obvious.
■  Accurate body surface markers, including: proximal femur, anterior superior iliac spine, posterior superior iliac spine, and sacrum.
■  The periphery of the left buttock is detachable, making it easy to observe the internal structure: the muscles, sciatic nerve, and vascular structures in the middle and top of the buttock.
■  Three muscle injection methods can be used for training: gluteus maximus injection, gluteus medius injection, gluteus minous injection, and lateral thigh injection.
