Sudoriferous Gland are small tubular structures that is helpful in producing sweat. These are exocrine gland and produces sweat on epithelial surface through duct.
Eccrine are present everywhere except ear canal, prepuce, labia minora and smaller than apocrine and excrete directly onto the surface of the skin and its proportion decreases with the age.
Apocrine are found in the armpit, areola in the ear and the eyelids. the secretory portion is larger than the eccrine glands and secrete swear into the pilary canal of the hair follicle.
