ENDOCRINE SYSTEM There are two types of glands: Exocrine glands that produce non-hormone secretions (sweat, sebum, saliva) have ducts through which these chemicals are transferred to the surface. Endocrine glands are ductless glands, that is, they do not have pouches or ducts.

endocrine glands pituitary gland or hypophysis cerebri. 1  approximately the size of a pea and located at the base of the brain; divided into two lobes; often referred to as the master gland because it produces hormones that stimulate the function of other endocrine glands.

What Is the Smallest Organ in the Human Body? The pineal gland is considered to be the smallest organ in the human body. Located deep inside the brain, the gland exists to produce a hormone vital in the regulation of the body clock. Melatonin in the only hormone that is secreted by the pineal gland.

Bulbourethral gland The bulbourethral glands are compound tubulo-alveolar glands, each approximately the size of a pea in humans. In chimpanzees, they are not visible during dissection, but can be found on microscopic examination.In boars, they are up to 18 cm long and 5 cm in diameter.They are composed of several lobules held together by a fibrous covering.n chimpanzees, they are not visible during dissection, but can be found on microscopic examination.

Salivary Gland Disease and Tumors In addition, 600-1000 tiny glands (the minor salivary glands) are located in the lips, inner cheek, and in the lining of the mouth and throat. The most common cause of problems in the salivary gland occurs when the ducts become blocked and saliva cannot drain. The parotid gland makes 25% of the saliva and drains into the mouth near the upper teeth. 2  The submandibular gland makes 70% of the salvia and drains into the mouth from under the tongue. 3  The sublingual gland makes 5% of the saliva and drains into the floor of the mouth.

Salivary Glands and Saliva Acini in the parotid glands are almost exclusively of the serous type, while those in the sublingual glands are predominantly mucous cells. In the submaxillary glands, it is common to observe acini composed of both serous and mucous epithelial cells.

Salivary Gland Disorders The salivary glands make saliva and release it into the mouth. There are three pairs of relatively large, major salivary glands: Parotid glands. Located in the upper part of each cheek, close to the ear. The duct of each parotid gland empties onto the inside of the cheek, near the molars of the upper jaw. Submandibular glands. Under the jaw. They have ducts that empty behind the lower front teeth. Sublingual glands. Beneath the tongue.

Salivary gland tumors The salivary glands are located around the mouth. They produce saliva, which moistens food to help with chewing and swallowing. There are 3 main pairs of salivary glands. The parotid glands are the largest. They are located in each cheek in front of the ears. Two submandibular glands are under the floor of the mouth under both sides of the jaw. Two sublingual glands are under the floor of the mouth. There are also thousands of small salivary glands lining the rest of the mouth.

- The three major salivary glands are the parotid gland, submandibular gland (also called the submaxillary gland), and sublingual glands. Saliva drains into the mouth through small tubes called ducts. The parotid gland makes 25% of the saliva and drains into the mouth near the upper teeth.

- A diagram of part of a salivary gland showing a serous acinus and mixed serous-mucous acinus. Salivary glands are made up of secretory acini (acini-means a rounded secretory unit) and ducts. There are two types of secretions-serous and mucous. The acini can either be serous, mucous, or a mixture of serous and mucous.

Sebaceous gland The structure consisting of hair, hair follicle, arrector pili muscles, and sebaceous gland is an epidermal invagination known as a pilosebaceous unit. Sebaceous glands are also found in hairless areas (glabrous skin) of the eyelids, nose, penis, labia minora, the inner mucosal membrane of the cheek, and nipples.

Mammary Gland - Anatomy & Physiology The mammary gland is a modified sweat gland that nourishes the young. It consists of the mamma and the teat. Undeveloped in both the male and female at birth, the female mammary gland begins to develop as a secondary sex characteristic at puberty.

- The major salivary glands consist of the parotids, located just in front of the ears, the submandibulars, located just under the jawline, and the sublingual glands, which are located in the floor of the mouth.

Sweat Glands Apocrine sweat glands: The apocrine are confined to axilla, eyelids (where they are known as Moll’s glands), nipple, and areola of the breast, perianal region and the external genitalia. They are larger than the eccrine glands and produce a thicker secretion having a characteristic smell.

Salivary gland Secretions can be increased by the presence, thought, or smell of food and also by thermal stimulation. In addition to numerous small glands in the tongue, palate, lips, and cheeks, human beings have three pairs of major salivary glands that open into the mouth through well-developed ducts. The parotid salivary glands, the largest of the three, are located between the ear and ascending branch of the lower jaw. Each gland is enclosed in a tissue capsule and is composed of fat tissue and cells that secrete mainly serous fluids. Each gland’s major duct (Stensen’s duct) opens in the rear of the mouth cavity near the second upper molar.

What are the three pairs of salivary glands? The 3 sets of salivary glands are as follows: parotid is the largest and is located near the poll (poll is the place right behind the ears.) submaxillary is located in the jaw …. sublingual is located under the tongue.

Parotid gland The parotid gland (often simply parotid) is a major salivary gland in many animals. In humans, the two parotid glands occur under the mouth and in front of both ears. They are the largest of the salivary glands.he gland is roughly wedge-shaped when seen superficially and on horizontal sections. The parotid duct, a long excretory duct, emerges from the anterior border of the gland, superficial to the masseter muscle.

Sweat gland Body of a sweat gland cut in various directions. 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.

Mammary gland The basic components of a mature mammary gland are the alveoli (hollow cavities, a few millimeters large) lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells. These alveoli join to form groups known as lobules. Each lobule has a lactiferous duct that drains into openings in the nipple.

- The pituitary gland or hypophysis is a small gland about 1 centimeter in diameter or the size of a pea. It is nearly surrounded by bone as it rests in the sella turcica, a depression in the sphenoid bone.
