Adrenal glands function  is the subject matter we are going to study now. In the series of free online medical transcription course, we have dealt about the anatomy of adrenal glands in the prior lesson. Adrenal glands have the outer adrenal cortex and the internal adrenal medulla covers. Both inner and outer covers of adrenal glands secrete different types of hormones and each hormone does its separate functions to maintain important functions of the human body. Adrenal Cortex Hormones: The hormones secreted by adrenal cortex are called as corticosteroids. Corticosteroids are of three types, such as, mineralcorticoids, glucocorticoids, and sexual hormones in male and female, such as, androgens, estrogens, and progestins. We will see about adrenal glands function of the cortex now. Mineralcorticoids: These hormones are essentially helpful in regulating the amount of electrolytes retaining in the body. Electrolytes are mineral salts. For the normal functioning ...

We are going to learn about adrenal glands function now.  Adrenal means above kidneys (ad- above, renal - related to kidneys). The another name of adrenal glands is suprarenal glands. Adrenal glands are endocrine glands as they have ducts. The two glands on the left and right of the kidney have different shapes. The right side adrenal gland is normally triangular in shape and the left side adrenal gland is semilunar in shape. While we are in stress situations, adrenal glands secrete hormones, such as, cortisol, catacholamines, and epinephrine. Function of the kidneys are also affected by the secretion of a hormone named as aldosterone by adrenal glands. Aldosterone controls osmolarity of plasma in blood. Adrenal glands are situated at the retroperitoneal area above kidneys on both sides. Adrenal glands have two different structures. The outer layer of adrenal glandd is adrenal cortex and the inner layer is medulla. Both adrenal cortex and medulla sec...

We are going to understand about anatomy of parathyroid and parathyroid gland function in this lesson. Parathyroid glands are four tiny glands that are present in the neck. These small glands produce a hormone known as parathyroid hormone. Parathyroid glands are oval in shape. They are present in the inferior part of thyroid glands on the both sides of the pharynx. In rare cases parathyroid glands are present within thyroid glands and in some patients they are present even in the chest area. The main function of the parathyroid hormone is to control the level of calcium in the blood and in the human bones. In abbreviated form the parathyroid hormone is referred as PTH. The another name parathyroid hormone is parathormone. This hormone helps in the function of moving calcium from the blood into the bones. Calcium is an essential mineral to maintain important body functions. Functions of the Parathyroid Glands: We get calcium mineral that is necessary fo...

I've missed to add some health abbreviations related to sense organs portions. As a learner of free medical transcription online, you should know about these important abbreviations that are used by physicians in training voice files and live voice files. You should all read and keep all these six abbreviations in your memory. The abbreviation for right ear is  AD, which means auris dextra. Left ear is  AS, which can be extended as auris sinistra, and to express both ears by the abbreviation AU, which is auris uterque. Left eye is termed as OS, its extension is oculus sinister. Right eye is denoted as OD, which means oculus dexter. Both eyes can be denoted as oculus uterque. HEENT is head, ears, eyes, nose, and throat. HEENT is often used in all medical transcription files in the physical examination area. EENT denotes ears, eyes, nose, and throat. A tube is placed in the eardrum, which is called in short as PE tube, which can be extended as polyethylene ventilating t...

Where is Thyroid Gland? This lesson will deal with thyroid gland and hypothyroidism and thyroid functions. The biggest endocrine gland in the human body is thyroid gland. It is situated in the neck inferiorly to the thyroid cartilage. Thyroid cartilage forms a prominence in that area named as Adam's apple. Thyroid gland consists of two lobes and isthmus is a bridge like structure that attaches two thyroid glands. Isthmus is situated under the cricoid cartilage. The two lobes of the thyroid gland are situated on both sides of the wind pipe or trachea. Thyroid gland functions as an important endocrine gland in the body. It has no ducts to pass their hormones into bloodstream. Thyroid gland secretes two important hormones, such as, thyroxine or tetraidothyroxine and triiodothyronine. Using iodine thyroid gland produces these hormones. Iodine is captured by thyroid glands from the blood and tyrosine. Thyroxine is much thicker hormone than triiodothyronine. We...
