difference between
sweat gland sebaceous gland
Answers
Answer:
The human skin has several types of exocrine glands (Latin, glandulae cutis), which release their biochemical products onto the skin surface. All skin glands consist by a secretory compartment, the gland or coil (tubulus), and an excretory part, the duct (ductus). Skin gland cells are of epithelial origin, but their secretory compartments are located at different depths in the dermis.
Three major types of skin glands are recognized according to their product, the excretory function, and the location, where the excretory ducts release their products (diseases of these glands are listed in Table 6-1). Regarding their product, skin glands are classified into glands secreting sebum (sebaceous glands) and sweat (sweat glands). Concerning their secretory function, skin glands are classified into holocrine glands, whose fully differentiated secretory cells burst and release both the cytoplasmic content and the cell membranes into their ducts, and merocrine glands, which excrete their product via exocytosis from secretory cells. Regarding the location where their ducts release their product, the ducts of sebaceous glands, in most cases, and apocrine sweat glands excrete their products into the hair follicle canal, and the eccrine sweat glands excrete directly onto the skin surface. Sebaceous glands are holocrine glands, and sweat glands (both eccrine and apocrine ones) are merocrine glands.
Explanation:
Both sweat and sebum are present in the layer of skin and mostly near the hair follicles.
