Question: What is racemose gland?...
What is racemose gland?
Solution
A gland is a collection of cells in the body of an animal that produce substances (such as hormones) for release into the bloodstream (endocrine gland) or into cavities within the body or on its surface (exocrine gland).
There are two types of glands:
Endocrine glands- The endocrine glands produce chemicals that circulate in the bloodstream. The glands discharge their contents into the bloodstream via the basal lamina. The basal lamina is a layer that surrounds the glands and contains a million, if not more, small blood vessels. Hormones secreted by these glands serve a crucial function in maintaining homeostasis.
Exocrine glands- Exocrine glands exude their contents via a duct onto the body's exterior or inner surface, such as the skin or the gastrointestinal tract. Direct secretion onto the apical surface.
Complete answer:
A racemose gland is a collection of tiny sacs that make up the secretory portion of a compound gland, also known as a compound alveolar gland or a compound acinar gland.
Saccular glands are alveolar glands that contain a sac-like secretory component. They are similar to alveoli, the extremely small air sacs in the lungs, in that they have an expanded lumen (cavity). A "racemose gland" is a type of "composite alveolar gland" or "compound acinar gland".
The pancreas is a compound racemose gland with features similar to the salivary glands, however it is softer and less compactly packed. The pancreatic juice, which is secreted and transported to the duodenum by the pancreatic duct, is a crucial digesting fluid.
Simple tubular glands, similar to those at the pyloric end of the stomach, but with shorter ducts; compound racemose glands, similar to the duodenal glands. This is one among the most basic glands. A sweat gland, for example, is a simple tube that is convoluted below.
Note:
Thyroid gland- The thyroid gland is placed directly below the larynx in the front of the neck. It measures about two inches in length and has a butterfly-like form. It secretes hormones that affect practically every tissue in your body.
Pituitary gland- The pituitary gland is a pea-sized gland located immediately behind the bridge of your nose at the base of your brain. The hypothalamus, which sits just above it, is in charge of it. Because it governs a number of other hormone glands, the pituitary gland is known as the master gland.
Hypothalamus- The hypothalamus serves as a communication centre for your pituitary gland, delivering signals and messages to the pituitary gland to cause it to generate and release hormones that cause other hormones to be produced and released.
Pineal gland- The pineal gland is found deep within the brain's centre. Melatonin is one of the hormones it secretes and controls. Melatonin is a hormone that aids in the regulation of sleep patterns. Female hormones, which control the menstrual cycle and fertility, are likewise regulated by the pineal gland.
