Exocrine glands are classified as unicellular and multicellular. The unicellular glands are scattered single cells, such as goblet cells, found in the mucous membranes of the small and large intestines. On the other hand, multicellular exocrine glands develop as secretory sheets, like the internal lining of the abdomen or chest. Such secretory sheets release their secretions directly into the lumen of these organs. In addition, some multicellular glands have deep-seated secretory units to...

The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
