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.

HUMAN BONE STRUCTURE - LESSON 200

-
Now in this post we will learn about the structure of the bone. In our human body there are 206 bones of different types are there. The thigh, lower leg, and upper and lower arm consists of long bones. These bones have large surface areas for muscle attachment and are very strong, are broad at the ends where they join with other bones. There are five types of bones in the human body. The five types are long, short, flat, irregular, and sesamoid. 1. Long bones:- These bones are comprised mostly of compact bone and lower amounts marrow, which is located within the medullary cavity, and spongy bone and are characterized by a shaft, the diaphysis, that is much larger in length than breadth. These bones are mostly present in the limbs, including those of the fingers and toes are long bones. Except the wrist, ankle, and kneecap these long bones are located in most. 2. Short bones:- These short bones are generally cube shaped and having a thin layer of compact bone surrounding a...

IMPORTANT RADIOLOGY NUCLEAR MEDICINE TERMS-3-LESSON 148

-
1. Magnetic resonance imaging- A magnetic ground radio signals are used to outline sagittal, coronal, and axial pictures of the body. 2. Megavoltage- High-energy radiation engendered by means of an equipment and employed in restorative x-ray analysis intended for cancer. 3. Nuclear medicine- This is a medical speciality, which examines and employs of radioactive materials called radionuclides within identification and treatment of ailment. 4. Orthovoltage- Emission of low-energy radioactive waves that are employed in pain-killing radiation therapy and exterior skin cancer diseases. 5. Palliative- Means just soothing or painkilling, not curing completely that is not possible. 6. PET scan or positron emission tomography- Radioactive materials are administered using intravenous route and these substances give out positrons. They generate a cross-sectional picture of the metabolism of the body. These images symbolize local concentration of the radio...

The Longest Medical Word

-
Image
Today, we will know about an interesting medical term in medical language. This post is just to know about a different thing in the medical language, though this word is used very rarely in our day-to-day medical transcription work. The longest medical word is "Pneumonoultramicroscopicsilicovolcanoconiosis"!!!!!. Can you read at least Pneumonoultramicroscopicsilicovolcanoconiosis.  Now, we will see the meaning of this word.  To know the meaning shall we split the word by word. Okay.  1.  Pneumono 2.  Ultramicrosopic 3.  Silico 4.  Volcano 5.  Conosis. So, Pneumonoultramicroscopicsilicovolcanoconiosis comprises of 5 medical words and in combination, they give a meaning of a certain kind of disease condition related to lungs.  Now, we will see the meaning of each to get the combined understanding of the longest medical word. Pneumono means lungs, ultramicroscopic - means minute, silico means silicon, volc...
