What are the subcutaneous layers?

- the reticular layer: The deepest layer of the dermis.
- hypodermis: A subcutaneous layer of loose connective tissue containing fat cells, lying beneath the dermis.
- the dermis: The layer of skin underneath the epidermis.
- the papillary layer: The most superficial layer of the dermis.
Which layer of skin is best for subcutaneous injection?
The location of injection is important for subcutaneous injections. The drug needs to be injected into the fatty tissue just below the skin. Some areas of the body have a more easily accessible layer of tissue, where a needle injected under the skin will not hit muscle, bone, or blood vessels.

Do you massage after a subcutaneous injection?
Do not massage area after injection. Withdrawing at the same angle as insertion minimizes discomfort to the patient and damage to the tissue. Proper needle disposal prevents needle-stick injuries. Massaging the area may spread the solution to the underlying subcutaneous tissue.
Which does 2 layers of the dermis have blood vessels?
Two layers make up the dermis. The papillary dermis, the thinner top layer, accounts for about 20% of the dermis. It contains both blood vessels and loose connective tissue and provides nutrition to the epidermis. The papillary dermis also controls skin temperature.
Which layer of the skin is composed of 2 layers?
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis , beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
