PHARMACOLOGY SUBDIVISIONS-LESSON 154

-
SUBDIVISIONS OF PHARMACOLOGY: In the previous lesson we came to know about the drugs, pharmacology and their subdivisions  In this lesson we come to know more about the various subdivisions.

1. Medicinal chemistry:- It is the study of synthesis of new drug and the relationship between chemical structure and biological effects.

2. Pharmacodynamics:- It involves the study of drug effects in the body i.e, 'Drug absorption' (how drugs pass into the blood stream), 'Metabolism' (changes drugs undergo within the body), and 'Excretion' (removal of the drug from the body).

3. Pharmocokinetics:- It explains the appearance and disappearance of the drug in the body overtime.

4. Molecular pharmacology:- It is the study of the interaction of the drugs and subcellar entities such as DNA, RNA and enzymes.

5. Chemotherapy:- It defines the study of drugs that destroy microorganisms, parasites, or malignant cells within the body.
It also includes the treatment of infectious diseases and cancer.

6. Toxicology:- It tries to explain the study of harmful chemicals and their effects on the body. These studies in animals are required by law before new drugs can be tested in humans. Antidotes are the substances given to neutralize unwanted effects of drug which a toxicologist is interested to find new and proper antidotes.

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

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
