Their terminations may he traced into the Pacinian and Meissners corpuscles, into and between the epidermic cells. They may be found in relation to the hair follicles, and in numbers around the coil glands. Their direct bearing on the diseases of the skin is obscure, and definite changes in them have been found only by a few favoured individuals, and not regularly even by them. T1 le Muscles of the skin are found mainly in relation to the hair follicles and sebaceous glands, where they take their origin. They are non-striped, and terminate high up in the corium, being attached to the connective tissue fibres. One of their functions is the expression of sebaceous material from the glands. Muscular fibres are also found in certain special situations, such as the scrotum and the nipple. Not of much importance pathologically, their spasmodic contraction increases very much the sufferings of the patient when the skin in these parts is inflamed. The structure of the nails is described in the section dealing o with their diseases.
