The occult significance of Aquarius is knowledge. Aquarius, the sign of the water bearer, is an eminently revolutionary sign. There are four types of knowledge or secret science. We need to know what these four types of knowledge are.
Upper limb. The upper limb or upper extremity is the region in a vertebrate animal extending from the deltoid region to the hand, including the arm, axilla and shoulder.
The lower extremity refers to the part of the body from the hip to the toes. It includes the hip, knee, and ankle joints, muscles, and bones. The lower extremity refers to the part of the body from the hip to the toes. The lower extremity includes the hip, knee, and ankle joints, and the bones of the thigh, leg, and foot. Many people refer to the lower extremity as the leg. In fact, the leg is the part of the body between the knee and ankle joints. The proper way to describe the lower limb is the lower extremity. This may seem like a minor detail.
