Exocrine gland By structure[edit] Exocrine glands contain a glandular portion and a duct portion, the structures of which can be used to classify the gland. 1  The duct portion may be branched (called compound) or unbranched (called simple).  The glandular portion may be tubular or acinar, or may be a mix of the two (called tubuloacinar).

- The correct answer is: ejaculatory duct. The ejaculatory duct is a duct which courses through the prostate gland and contains only semen. Remember, semen is the combination of sperm from the ductus deferens, seminal fluid from the seminal vesicle, and secretions of the prostate gland.The ejaculatory duct is formed by the union of the duct of the seminal vesicle and the ampulla of the ductus deferens, and it is the site where sperm and seminal fluid mix.The prostatic urethra is also contained in the prostate gland, and it carries semen, but it also carries urine out of the bladder.emember, semen is the combination of sperm from the ductus deferens, seminal fluid from the seminal vesicle, and secretions of the prostate gland.

Mammary Glands and Ducts In Depth: Mammary Glands and Ducts. The word “mammary” is similar to “mammal” because our classification in the animal kingdom is named after our glands. The presence of sweat glands is a distinguishing characteristic for mammals. The glands and ducts of the female breast are similar to sweat glands.

Duct System Ejaculatory Duct. Each ductus deferens, at the ampulla, joins the duct from the adjacent seminal vesicle (one of the accessory glands) to form a short ejaculatory duct. Each ejaculatory duct passes through the prostate gland and empties into the urethra.ach ductus deferens, at the ampulla, joins the duct from the adjacent seminal vesicle (one of the accessory glands) to form a short ejaculatory duct.

- A salivary duct stone is a calcification in the salivary gland, which blocks the flow of saliva in the mouth. Stones most often form in the base of the mouth; however, the deposits can form on the cheeks and under the tongue.Most individuals who experience stones have multiple deposits.s salivary gland stones are caused by the buildup of calcium and other minerals in the salivary gland, treatment focuses on naturally dissolving the buildup. Common treatments include apple cider vinegar, lemon juice and oregano oil.

Differences Between Endocrine and Exocrine Glands Exocrine Glands. Exocrine gland is a gland that secretes chemical substances into ducts. As an example, sweat gland and salivary glands. In salivary glands, saliva is produced within the gland, and it secrets into saliva duct and travels to the surface.land is a specific structure which secrets various chemical substances such as enzymes, hormones, and metabolites. There are two types of glands in the body called endocrine glands and exocrine glands. Throughout the embryo development, endocrine glands lack ducts and remain as blocks of tissue.

Sweat gland Generally, sweat glands consist of a secretory unit consisting of a base rolled into a glomerulum, and a duct that carries the sweat away. The secretory coil or base, is set deep in the lower dermis and hypodermis, and the entire gland is surrounded by adipose tissue.

Ceruminous adenoma Malignant ceruminous gland tumors tend to be ulcerative and infiltrating rather than obstructive/occlusive. Ceruminous glands are located in the deeper dermis of the external ear canal. They are believed to be modified apocrine sweat glands that secrete waxy cerumen instead of watery sweat. In the normal dog and cat the ducts of the ceruminous glands are virtually non-visable. The classic appearance of ceruminous hyperplasia is multiple, often numerous, punctuate nodules or vesicles, usually less than 2mm in diameter, in the external ear canal and inner pinna. They are dark blue, brown or black.

0.2 Integumentary system module 3: accessory structures of the  (Page 3/33) An apocrine sweat gland is usually associated with hair follicles in densely hairy areas, such as armpits and genital regions. Apocrine sweat glands are larger than eccrine sweat glands and lie deeper in the dermis, sometimes even reaching the hypodermis, with the duct normally emptying into the hair follicle.

Sialolithiasis From Wikipedia, the free encyclopedia. Sialolithiasis (also termed salivary calculi, or salivary stones), is a condition where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed  Wharton's duct ).bout 85% of stones occur in the submandibular gland, and between 5-10% occur in the parotid gland. In about 0-5% of cases, the sublingual gland or a minor salivary gland is affected. When minor glands are rarely involved, caliculi are more likely in the minor glands of the buccal mucosa and the maxillary labial mucosa.

Salivary gland The salivary glands in mammals are exocrine glands, glands with ducts, that produce saliva.They also secrete amylase, an enzyme that breaks down starch into maltose. minor salivary gland may have a common excretory duct with another gland, or may have its own excretory duct. Their secretion is mainly mucous in nature (except for Von Ebner glands-see next section) and have many functions such as coating the oral cavity with saliva.
