The subcutaneous tissue (from Latin subcutaneous ‘beneath the skin’), also called the hypodermis, hypoderm (from Greek ‘beneath the skin’), subcutis, superficial fascia, is the lowermost layer of the integumentary system in vertebrates.

Is the subcutaneous layer made of squamous epithelium?

The skin is composed of three layers of tissue: the outer epidermis (made of stratified squamous epithelium ), the middle dermis (made of fibrous connective tissue ), and the inner subcutaneous layer connective tissue ), and the inner subcutaneous layer or hypodermis (made of adipose tissue and loose connective tissue) …

Is reticular layer of skin vascular?

Reticular Layer

This layer is well vascularized and has a rich sensory and sympathetic nerve supply. The reticular layer appears reticulated (net-like) due to a tight meshwork of fibers. Elastin fibers provide some elasticity to the skin, enabling movement.

What is the white layer of skin called?

Dermal white adipose tissue is a unique layer of adipocytes within the reticular dermis of the skin. Recently, several nonmetabolic activities have been discovered for dWAT and its fibroblast precursors. These functions include antimicrobial defense and roles in hair cycling, wound healing, and thermogenesis.
