Conjunctivitis || type of Conjunctivitis || Infectious Conjunctivitis || Eyeball

Acute conjunctivitis is an eye condition involving inflammation of the conjunctiva of the eye. Inflammation of the conjunctiva of the eye can occur from infectious and non-infectious causes, including allergic, viral and bacterial infections. Allergic, bacterial and viral conjunctivitis are the 3 most common types of acute conjunctivitis, each of which has different pathophysiological mechanisms, signs and symptoms and ways they are diagnosed and treated. In this lesson, we discuss the pathogenic organisms that cause both bacterial and viral conjunctivitis, how to distinguish between allergic, bacterial and viral conjunctivitis, how they are diagnosed and how they are treated.

What is Immunity || Active & Passive Immunity|| IMMUNITY IN HINDI | TYPES OF IMMUNITY

The immune system (or immunity) can be divided into two types - innate and adaptive immunity. This video has an immune system animation. The innate immune system consists of defenses against infection that are activated instantly as a pathogen attacks. Adaptive immunity (or acquired immunity) is a subsystem of the immune system that contains highly specialised systemic cells and processes that kill pathogens and prevent their growth in the body. Innate vs adaptive immunity: it’s important to realize that innate and adaptive immunity are different. Their differences are explained in the video in layman terms.

Our immune system is a fascinating entity, that functions in quite a unique and efficient manner. Comprising of various types of cells, it is prepared for any kind of breach in the fortress of our body, and is equipped to fight off a staggering number of intruders.
In this video, we give you a brief overview of the immune system, and the basic types of cells involved, along with the function they carry out.

Each cell if the immune system carries out various roles, depending on the kind of threat the body is facing. However, they have certain basic roles which have been explained here.

ANATOMY OF INNER EAR 👂 👂 || ANATOMY PHYSIOLOGY OF EAR

Ear anatomy & physiology in Hindi | Part 1 | Structure | Functions | Outer ear | Middle ear

Welcome to my channel Power of Knowledge academy. In this video you will learn about the structure and function of Human ear.
Here is the brief script that you will learn in detail in the video.
What is the ear?
Your ears are organs that detect and analyze sound. Located on each side of your head, they help with hearing and balance.
What is the main function of the ear?
Your ears have two main functions: hearing and balance.
Hearing: When sound waves enter your ear canal, your tympanic membrane (eardrum) vibrates. This vibration passes on to three tiny bones (ossicles) in your middle ear. The ossicles amplify and transmit these sound waves to your inner ear. Once the sound waves reach your inner ear, tiny hair cells called stereocilia transform the vibrations into electrical energy and send it along nerve fibers to your brain.
Balance: Your inner ear contains semicircular canals filled with fluid and hair-like sensors. When you move your head, the fluid inside these loop-shaped canals sloshes around and moves the hairs. The hairs transmit this information along the vestibular nerve to your brain. Finally, your brain sends signals to your muscles to help you stay balanced.
What are the parts of the ear?
The three main parts of your ear include the outer ear, middle ear and inner ear. Your tympanic membrane (eardrum) separates your outer ear and middle ear.
Outer ear (external ear):
Your outer ear is the part of your ear that’s visible. It’s what most people mean when they say “ear.” Also called the auricle or pinna, your outer ear consists of ridged cartilage and skin, and it contains glands that secrete earwax. Its funnel-shaped canal leads to your eardrum, or tympanic membrane.
Middle ear:
Your middle ear begins on the other side of your tympanic membrane (eardrum). There are three tiny bones in this area — the malleus, incus and stapes. (Healthcare providers refer to these three bones as the ossicles.) They transfer sound vibrations from your eardrum to your inner ear. Your middle ears also house the eustachian tubes, which help equalize the air pressure in your ears.
Inner ear:
Your inner ear contains two main parts: the cochlea and the semicircular canals. Your cochlea is the hearing organ. This snail-shaped structure contains two fluid-filled chambers lined with tiny hairs. When sound enters, the fluid inside of your cochlea causes the tiny hairs to vibrate, sending electrical impulses to your brain.
The semicircular canals, also known as the labyrinthine, are responsible for balance. They tell your brain which direction your head is moving.

Outer Ear | External ear of human | Anatomy of ear | ear drum | anatomy & physiology | tympanic

The outer ear is situated superficially next to several bony landmarks. It is posterior to the zygomatic process of the temporal bone as well as the proximal part of the mandibular process and the auricular surface of the mandibular notch. Superior to it is the squamous part of the temporal bone, while the styloid process is located inferiorly. Finally, the mastoid process of the temporal bone lies posteroinferiorly with respect to the outer ear. There is very little subcutaneous tissue between the auricular scaffold and the overlying skin of the ear. The skin, however, continues into the external acoustic meatus and covers the lateral surface of the tympanic membrane.

Before the different parts of the external ear can be discussed, it is important to note that the left and right ears are optical isomers of themselves (similar to the left and right hands). This is relevant because the different parts of the external ear can be related to a clock face. However, the position of one structure, for example the tragus, will be in a 9 o’clock position on the left, but in a 3 o’clock position on the right. The left ear will be used as an example throughout, but keep in mind the mirroring necessary to discuss the right ear.

On that note, the tragus is the first of several cartilaginous flaps in the ear. As previously mentioned, it projects posteriorly from the 9 o’clock position to provide a lateral border to the distal end of the external acoustic meatus. Posteroinferior to the tragus in the 5 o’clock position is the antitragus. It is also a cartilaginous structure that is separated from the tragus by an intertragic notch. Superior to the tragus in the 10 o’clock position is the crus of the helix. It starts at the co**ha of the auricle (depression at the or***ce of the external auditory meatus that corresponds with the protruding eminentia co**hae on the posterior surface of the ear) and extends anterosuperiorly in the 10 o’clock position (superior to the tragus) and continues as the prominent ridge known as the helix. The helix is the outermost concaved section of the ear and it has a small protuberance at the 2 o’clock position called the auricular tubercle. The helix continues inferiorly and ends in the 4 o’clock position at the tail of the helix. Another raised cartilaginous structure called the antihelix mirrors the path of the helix. Apically, the antihelix has two crura surrounding a depression known as the triangular fossa. The antihelix is separated from the helix by the scaphoid fossa (corresponding to the eminentia scaphae on the posterior aspect of the external ear). Finally, in the 6 o’clock position is the soft, fibrofatty structure called the lobule.

There are two groups of muscles associated with the external ear. The intrinsic group of muscles consists of the tragicus and antitragicus, obliquus auriculae, transversus auriculae and the helicis major and minor. The tragicus muscle lies vertically on the lateral aspect of the tragus. It is a flat, short muscle that is perpendicular to (but not in contact with) the antitragicus muscle. Antitragicus originates from the anteroinferior part of the antitragus to the tail of the antihelix and helix. Helicis minor travels obliquely along the crus of the helix, while helicis major courses over the anterior boundary of the helix after travelling vertically over its spine. The obliquus auriculae and transversus auriculae muscles are found on the posterior (cranial) part of the external ear. The former extends from the upper part of the eminentia scaphae to the eminentia co**hae, while the latter bridges the inferior aspect of the same two structures.

The extrinsic muscle group includes the anterior, posterior and superior auricular muscles. Auricularis posterior originates as three aponeurotic muscular fasciculi from the mastoid process to insert in the ponticulus (oblique ridge on the eminentia co**hae) on the cranial aspect of the external ear. Auricularis anterior begins in the epicranial aponeurosis and inserts in the spine of the helix. It is the smallest of the three extrinsic muscles. Thirdly, auricularis superior is the largest of the extrinsic muscles. It also begins at the epicranial aponeurosis and inserts in the cranial part of the auricle.

The extrinsic muscles have limited impact on the movement of the external ear. The intrinsic muscles, however, are able to modify the shape of the auricle to a minor degree. Helicis major is known to move the auricle anteriorly and superiorly.
