Equilibrium and Inner Ear - Lesson 280

-


In this post, we will learn about inner ear equilibrium. We all know already that human ear has three parts, such as, outer ear or pinna, middle ear, and inner ear. Each ear has its own significance in sending sound waves from our surroundings to the brain. The inner ear is an important area in maintaining equilibrium in the brain. What is equilibrium? Equilibrium is the feeling of balance. Balance of being is maintained by the inner ear. If one is off balance, then that state is called dizziness. Dizziness is purely a physical state and this equilibrium is maintained by three canals in the inner ear. Now we will see in detail about this now.

Inner Ear Equilibrium Problems: Inner ear has three organs that are responsible for balance. The name of these three semicircular tubes are semicircular canals, saccule, and utricle respectively. These three tubes contain a liquid named as endolymph and small sensitive hair like cells inside it. When we move head, this liquid is fluctuated because of the movement of the head. Due to this fluctuation, impulses are formed within the hair cells and so the vibration is transformed to the brain. Then the communication from the brain is sent to the muscle cells in all parts of the body and so inner ear equilibrium is maintained.

Auditory Receptors:   In the inner ear, the auditory liquids and auditory receptors are present inside an organ named organ of Corti in the labyrinth. Due to the problem in the inner ear, we are getting some abnormal conditions, such as benign positional vertigo, Miniere's disease, labyrinthitis or any other tumors. Benign positional vertigo is a disease condition of inner ear equilibrium. In the next lesson, we will learn about vocabularies of eyes and ears. Okay. Come on.

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
