Topics covered in this video: • What are joints?• Joint classification based on structure and function• Types of joints in the human body• Examples of fibrous, cartilaginous, and synovial joints• Subtypes of each joint category with real anatomical examples• Clinical relevance of joints (e.g., high ankle sprains, TMJ, arthritis)• Supporting structures: ligaments, bursae, menisci, labrum, fat pads• Functional mobility: synarthrosis, amphiarthrosis, diarthrosis• Synovial joint types: – Ball-and-socket joint (shoulder, hip) – Ellipsoid joint (wrist) – Saddle joint (thumb) – Hinge joint (elbow, knee, fingers) – Pivot joint (atlantoaxial, radioulnar) – Plane joint (acromioclavicular, vertebral facet joints) Joint classification explained:• Fibrous joints – sutures (suturae), syndesmoses, gomphoses• Cartilaginous joints – synchondroses (hyaline cartilage), symphyses (fibrocartilage)• Synovial joints – contain a joint cavity filled with synovial fluid – include articular cartilage, synovial membrane, joint capsule – supported by ligaments, tendons, labrum, bursae, menisci Clinical anatomy references include:• Atlantoaxial joint (articulatio atlantoaxialis mediana)• Glenohumeral joint (articulatio humeri)• Temporomandibular joint (articulatio temporomandibularis)• Proximal radioulnar joint (articulatio radioulnaris proximalis)• Pubic symphysis (symphysis pubica)• Costochondral joints (junctiones costochondrales)• Intervertebral discs (disci intervertebrales)• Distal tibiofibular syndesmosis (syndesmosis tibiofibularis distalis) Whether you’re a medical student or revising anatomy for clinical practice, this video breaks down complex arthrology in a visual, memorable way. Transcript  0:00Joints. They come in many forms, but at their core, joints exist to link bones0:05together and allow movement. Some let you rotate your arm in every direction,0:10some move just a little bit, and some, like the joints in your skull, don’t move at all.0:16You don’t really think about them, until something goes wrong. When joints wear down,0:21become inflamed, or stop working properly, even the simplest movements can become difficult.0:27So, why are some joints flexible while others are completely rigid? What makes0:32one joint allow movement while another barely moves at all? And how do we actually classify0:38all the different joints in the body? In this video, we’ll start by answering0:43the fundamental question – what are joints? Then, we’ll go through all the joints in the body and0:49classify them based on their structure and function. As we go through them,0:54we’ll also highlight their clinical relevance, understanding how joint problems develop and0:58what makes them vulnerable to damage. Hey everyone, my name is Taim. I’m a1:02medical doctor, and I make animated medical lectures to make different topics in medicine1:06visually easier to understand. If you’d like a PDF version or a quiz of this presentation, you can1:11find it on my website, along with organized video lectures to help with your studies.1:15Alright, let’s get started! So what are joints?What are Joints?1:19Just, in simple terms, The point at which two bones lay adjacent to each1:24other (with or without the ability to move) is called a joint. Let’s visualize this.1:30Here we see a bone. Here is another bone. The point at which they lay adjacent to1:35each other is a joint. Here are two bones, between them, a joint. Here are two bones,1:41between them a joint. And even, I’ll surprise you now. Even between your skull bones, is a joint.1:48So joints come in different shape, and they are structurally and functionally different.1:54For example. The shoulder joint is1:56called the glenohumeral joint. Structurally, we call this a Synovial joint, Functionally,2:02it’s a Diarthrosis, since it’s a freely movable joint. And we subclassify it as a ball-and-socket2:09joint, which provides free rotational movement. Between the articular surfaces of vertebrae,2:15we got the facet joint, or zygapophyseal joints. They are synovial joints,2:20functionally movable so diarthrosis as well, but subclassified as plane joint,2:26allowing only gliding movements. Okay, let’s take another example, in the skull we got2:32sutures. Or lambdoid suture is what we’re pointing at specifically now. Structurally,2:37it’s a strong fibrous joint. And functionally, a Synarthrosis, meaning a joint that does
