Skin
Infections
The nail folds, hair follicles, and sebaceous glands are common sites for entrance into the underlying tissues of pathogenic organisms such as Staphylococcus aureus. Infection occurring between the nail and the nail fold is called a paronychia. Infection of the hair follicle and sebaceous gland is responsible for the common boil. A carbuncle is a staphylococcal infection of the superficial fascia. It frequently occurs in the nape of the neck and usually starts as an infection of a hair follicle or a group of hair follicles

Sebaceous
Cyst
A sebaceous cyst is caused by obstruction of the mouth of a sebaceous duct and may be caused by damage from a comb or by infection. It occurs most frequently on the scalp.
Shock
A patient who is in a state of shock is pale and exhibits gooseflesh as a result of overactivity of the sympathetic system, which causes vasoconstriction of the dermal arterioles and contraction of the arrector pili muscles

Fasciae
and Infection
A knowledge of the arrangement of the deep fasciae often helps
explain the path taken by an infection when it spreads from its primary site.
In the neck, for example, the various fascial planes explain how infection can
extend from the region of the floor of the mouth to the larynx
