The onset of action of subcutaneous insulin glargine is somewhat slower than NPH human insulin.

A small amount is immediately available for use, and the remainder is sequestered in subcutaneous tissue.

Subcutaneous fat Most of the remaining nonvisceral fat is found just below the skin in a region called the hypodermis.

The most common method is by using gun calipers to measure the thickness of subcutaneous fat in multiple places on the body.

In the integumentary system, which includes the skin, it accumulates in the deepest level, the subcutaneous layer, providing insulation from heat and cold.

Anatomical features In humans, adipose tissue is located beneath the skin (subcutaneous fat), around internal organs (visceral fat), in bone marrow (yellow bone marrow) and in the breast tissue.

This subcutaneous fat is not related to many of the classic obesity related pathologies, such as heart disease, cancer, and stroke, and some evidence even suggests it might be protective.
