<P> The subcutaneous tissue ( from Latin subcutaneous , meaning `` beneath the skin '' ) , also called the hypodermis , hypoderm ( from Greek , meaning `` beneath the skin '' ) , subcutis , or superficial fascia , is the lowermost layer of the integumentary system in vertebrates . The types of cells found in the hypodermis are fibroblasts , adipose cells , and macrophages . The hypodermis is derived from the mesoderm , but unlike the dermis , it is not derived from the dermatome region of the mesoderm . In arthropods , the hypodermis is an epidermal layer of cells that secretes the chitinous cuticle . The term also refers to a layer of cells lying immediately below the epidermis of plants . </P>
