Goitre - Causes of Thyroid Problems - Lesson 320

What causes thyroid problems? There are many abnormal conditions that causes thyroid problems. One of the abnormal condition of thyroid is goiter. What is goiter? Goiter is an abnormal state of enlargement of the thyroid gland. This is not a symptom for any one disease. Goiter may be a reflection of more than one disease conditions. There are two kinds of goiters, such as endemic goiter and nodular or adenomatous goiter. Now we will see about each goiter types one by one.

Endemic Goiter: Endemic means inside. We will see what causes this thyroid problem now. This is meant as goiter inside. Endemic goiter occurs in a patient because of a deficiency condition of iodine in the food of the patient. When this forms, a celluloid material, which seems like a gel is collected in the thyroid gland. This collection of celluloid liquids makes the gland big in size. This is an expression of struggle of the body to compensate the less iodine in the body. Endemic goiter can be cured by the intake of more iodine food or through supply of iodine material inside the body. The figure below is an example of endemic goiter.

Nodular Goiter or Adenomatous Goiter: The second type of goiter is nodular goiter. The another name of nodular goiter is adenomatous goiter. In this type of goiter, the thyroid gland gets enlarged, as well as addition of some nodules and adenomas inside the goiter. The another terminology for enlargement is hyperplasia. Hyperplasia means abnormal growth.

Symptoms of Goiter:  The common symptoms of goiter may be nervousness, excessive sweating, high pulse rate or tremor etc.

Treatment: Common treatment for goiter is to suppression of thyroid-stimulating hormone or TSH. The patient will be injected with thyroid hormone.

Physiology of Cells - Lesson 319

This is about physiology of cells, all should know about this topic very clearly of what are the nuts and bolts of a cell. The topics covered here are cytoplasm, golgi bodies, diffusion, filtration process of cells, phagocytosis, cytopenesis, and cilia. All medical transcription learners should know about physiology of a cell. We will see about one by one now.

1. Cytoplasm: The portion of the protoplasm outside the nucleus of cells is called as cytoplasm.

2. Golgi Bodies: These are complex packages secretions for export from the cell and golgi bodies producer lysosomes.

3. Diffusion Process: This is the process of movement of ions from regions of higher to lower concentration.

4. Filtration: This is the process by which a substance is forced through a membrane by hydrostatic pressure.

5. Phagocytosis: The process of white cells in getting other substances is phagocytosis.

6. Cytopenesis: The duplication of chromosomes prior to cell division of cytoplasm to form two cells is termed as cytopenesis.

7. Tissues: Each tissue is combination of cells.

8. Epithelial Cells: They are classified according to their shape, such as, squamous, columnar and cuboidal.

9. Gland: Any structure that is differentiated to produce a secretion is called as a gland.

10. Muscle Tissue: It consists of bundles or sheets of long, narrow cells arranged in parallel and having the capacity to shorter under appropriate stimulation is neuron.

11. Cardiac Muscle: The muscle found only in the heart wall is called as cardiac muscle.

12. Nervous Tissue: They are specialized to transmit neural impulses.

13. Cilia: They are tiny hair like organelles projecting from the surfaces of many types of cells that help move materials outside a cell.

Important Suffixes and Prefixes Used in Medical Transcription - Lesson 318

Today we will see about important suffixes and prefixes that are used in medical transcription field commonly on a daily basis. Every transcriptionist must memorize these words with its meanings. Next two posts will follow  this topic. I am going to add more videos hereafter for each topic. Many new changes will happen soon in our blog. We need your support as usual. Now we will see important suffixes and prefixes used in medical transcription one by one now.

1. -tomy means cutting or incision

2. -graphy means process of writing or recording

3. -oligo means scany or deficient

4. -logy means study of

5. super- means above or excessive

6. -uria means pertaining to urine

7. inter- means between

8. -pathy means disease

9. post- means after

10. -plasia means development or growth

Endocrine Terms - Lesson 317

Today we will see about some important endocrine medical terms. These terms are very much important about endocrine system. Studying about these important terms are really helpful when listening these terms while doing training files or while doing live files. Read the terms and understand the meaning of each clearly. We will see about some important hormones related to the endocrine systems too in this lesson. We will see about catacholamines, vasopressin,corticosteroids,glucocortcoid, and mineralocorticoid. 

Catacholamines: These are important hormones that are derived from an amino acide. Catacholamines are produced by adrenal medulla. The best example for a catacholamine is epinephrine.

Vasopressin: This hormone is secreted by the back lobe or postrerior lobe of the pituitary gland. This area of the brain is also named as neurohypophysis. The another name of vasopressin is antidiuretic hormone.

Corticosteroids: These are hormones that are produced by the adrenal cortex. Corticosteroids are steroid hormones. The best example for these types of hormones are mineralocorticoids and glucocorticoids. We will see about these two steroid hormones one by one below.

Glucocorticoids: Adrenal cortex secretes glucocorticoid hormones. These hormones are helpful for the body and that are helping the human body to use essential chemicals, such as, sugars, proteins and fats inside the body in the blood. Glucocorticoids are also useful for the body to produce normal stress responses from the brain.

Mineralocorticoids: These hormones are produced by the adrenal cortex. Mineralocorticoids are helpful in regulating electrolytes in the body (minerals). The balance of water is managed by mineralocorticoids in the body. The best example of mineralocorticoid type hormone is aldosterone.

In the next lesson, we will see about other important endocrine system related terms, such as, sympathomimetic, steroid, sella turcica, hypothalamus, hormone, homeostasis, and electrolyte. Okay. Come on.
