Body Cells and Differentiation-Lesson 1

-

Body cells are different types. We often may read about stem cell types. Like in a movie there are many actors to do their different roles to establish a story, in our body there are different kinds of cells to do different roles to keep the body stable and active.

The cells in our body are of two types:
1. Somatic cells. Our body contains Muscle cells, Nerve cells, Skin cells, and Fat cells. These kind of cells performing mainly body related functions and so they are called Somatic cells. There are varieties of cells inside the body. Every cell is different or specially created to do their special role inside the body throughout.

Fat Cell: For example in body cells a FAT CELL has in it empty and large spaces for fat storage, and a muscle is slender and long and has in it fiber material that help in relaxing and contracting, as well as a skin cell is square in shape and also flat in structure to give protection to our body and a nerve cell which is long in structure and also has many types of extensions of fibers those help in its work of impulses carrying.

Sex cells:  These cells do reproductive activities like cell division and help in producing a fetus.

A cell is performing one or more specific functions. There are five types of body cells in the human body:
We can divide them into two groups, such as SOMATIC CELLS AND SEX CELLS.

SOMATIC CELLS: They are called as body cells because they perform body related functions like contraction, expansion, protection, communication of information, and movements etc. They are of four types:

1. Epithelial cell - These cells found as the lining and covering of organs and body cavities.

2. Connective cell- these cells supports as bone, cartilage, tendons and ligaments, protects as the bony cavities and as protective immune cells in the blood, and stores nutrients.

3. Nervous cell- these cells, which carry information in the form of impulses throughout the body.

4. Muscle cell - these cells contract to perform movements such as skeletal muscle movements, GI tract propulsion, and pumping of blood in the heart.

SEX CELLS:
These cells perform activities related reproduction. Thus, different kinds of cells in our body performing different actions.

Ok, next we move on to the next lesson...come on...

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...
