Tissues and its Functions

-


Combination of a group of similar or same kind of cells. They combine to work together to do a particular or specific job. For example,

a) EPITHELIA TISSUE is lining the internal organs of our body i.e. their function is to lining an organ that is these tissues covering the outside of the body organs, as well as inner suface of internal organs too. Epi-means outer.

b) MUSCLE TISSUE, two types of muscle tissues (voluntary and involuntary), voluntary muscles are controlling our arms and legs where the movement is voluntary i.e. movement is in our control. At the same time involuntary muscles is in our heart (CARDIAC MUSCLE-a specialized muscle found in the heart) and gastrointestinal system, and also other parts of the body too where the movement is involuntary i.e. not in our control.

c) CONNECTIVE TISSUE, blood, fat, cartilage, and bone are the examples of connective tissue, because they differ much from other tissues. CARTILAGE is an elastic fibrous tissue attached bones. There are two types of connective tissues a) LOOSE CONNECTIVE TISSUES b) DENSE CONNECTIVE TISSUES.

Loose connective tissues are found in the AREOLAR, ADIPOSE, AND RETICULAR AREAS.Dense connective tissues are found in the CARTILAGE, BLOOD, BONE, AND LYMPHATICS.

d) NERVE TISSUE: They conduct sensory and motor impulses from the CENTRAL NERVOUS SYSTEM to and fro all over the body.

Now you can understand what is a TISSUE and how they are spread all over the body and functioning in short... We will study them later extensively..

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

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, volcano means eruption, and conosis means abnorm
