Cutis verticis gyrata is a medical condition usually associated with thickening of the scalp. [1] The condition is identified by excessive thickening of the soft tissues of the scalp and characterized by ridges and furrows, which give the scalp a cerebriform appearance.
The epidermis is the most superficial layer of skin, a squamous epithelium with several strata: the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. [8] Nourishment is provided to these layers by diffusion from the dermis since the epidermis is without direct blood supply.
The effect of the lesions varies, from minor damage to the epithelium (superficial punctate keratitis), to more serious consequences such as the formation of dendritic ulcers. [3] Infection is unilateral, affecting one eye at a time. Additional symptoms include dull pain deep inside the eye, mild to acute dryness, and sinusitis. Most primary ...
Superficial (from Latin superficies ' surface ') describes something near the outer surface of the organism. [1] For example, in skin , the epidermis is superficial to the subcutis . [ 27 ]
It is closely connected to the integument by the firm, dense, fibro-fatty layer which forms the superficial fascia of the scalp. It is attached to the pericranium by loose cellular tissue, which allows the aponeurosis, carrying with it the integument, to move through a considerable distance.
Malassezia furfur is a fungus that lives on the superficial layers of the dermis.It generally exists as a commensal organism forming a natural part of the human skin microbiota, but it can gain pathogenic capabilities when morphing from a yeast to a hyphal form during its life cycle, through unknown molecular changes.

The superficial squamous cells have a clear, seemingly empty cytoplasm but it has not been shown that there is an increase in intracellular water, possibly making the term edema misleading. The histologic appearance is thought to be caused by water within the cells of the spinous layer causing the light to reflect back as whitish.
The superficial layer then attaches to the lateral aspect of the superior border of the arch, and the deep layer to its medial aspect. [1]: 357 The space between the two layers is occupied by adipose tissue and contains a branch of the superficial temporal artery, and the zygomaticotemporal nerve. [1]: 357
