synovial joint and arthritis

the medipoint

Synovial fluid, also called synovia, is a viscous, non-Newtonian fluid found in the cavities of synovial joints. With its egg white–like consistency, the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement.

A very thin layer of slippery, viscous joint fluid, called synovial fluid, separates and lubricates the two cartilage-covered bone surfaces. A healthy knee …

Synovial Joint Definition
A synovial joint is a connection between two bones consisting of a cartilage lined cavity filled with fluid, which is known as a diarthrosis joint. Diarthrosis joints are the most flexible type of joint between bones, because the bones are not physically connected and can move more freely in relation to each other. In synarthrosis and amphiarthrosis connections between bones, the bones are directly connected with fibrous tissue or cartilage, limiting their ultimate range of motion.

Structure of a Synovial Joint
Although the exact structure of a synovial joint may vary depending on the function of the joint and the animal it is in, the general structure of each joint is the same. Extending from the periosteum of the bone, an articular capsulemade of cartilage and other fibers encapsulates the entire joint. Inside the articular capsule, a synovial membrane creates a sac which holds a specialized hydraulic fluid, called synovial fluid. This fluid creates a lubricating cushion between the two bones, allowing them to glide past one another. The ends of the bones are protected in another layer of articular cartilage

Joint Classifications and Types | Skeletal System 04 | Anatomy & Physiology

1. Classification of joints – fibrous (fixed), cartilaginous (slightly moveable), synovial (freely moveable).
2. Structure and function of components of synovial joints (joint capsule, bursa, articular cartilage, synovial membrane, synovial fluid, ligaments).
3. Six types of synovial joints (ball and socket, condyloid, gliding, saddle, hinge, pivot).

Body Movement Terms Anatomy | Body Planes of Motion | Synovial Joint Movement Terminology

Body movement terms compilation video: learn the body planes of motion (synovial joint movement terminology) for anatomy or kinesiology courses. This is a compilation video that covers all of the anatomical terms of motion.

Synovial joints are capable of various movements. In anatomy, body movement terms help explain the different types of movements that can occur. Nurses and other healthcare professionals use these terms during assessments, documentation, and more.

Quiz: https://www.registerednursern.com/movement-terms-quiz/

There are four general categories of movements:
1. Gliding movements
2. Angular movements (flexion and extension, abduction and adduction, and circumduction)
3. Rotational movements (medial / internal rotation and lateral / external rotation)
4. Special movements (such as plantarflexion, dorsiflexion, retrusion, protrusion, protraction, retraction, excursion, elevation, depression, inversion, eversion, supination, and pronation).

These anatomical terms of motion may seem complex, but they are easy to understand once you practice and use a few simple mnemonics. These movements often occur within the major body planes.

A joint is a place where two or more bones meet, also called an articulation
These joints allow us the free movement to perform skills and techniques
during physical activity. Synovial joints are classified into 6 (six) different categories on the basis of the shape and structure of the joint.

It’s made of:
Cartilage: Covers the bone, absorbs shocks, reduces bone friction
Joint capsule: Keeps the joint’s bones together
Synovial Fluid: Found in the joint’s cavity and lubricates the joint
Synovial membrane Produces synovial fluid
Along with these, the synovial joint is typically surrounded by tissue that holds up the joint and helps promote movement.

How To Roll A Cross Joint

joints No Comments »

This is a step by step tutorial on How To Roll A Cross Joint
(Intended for the 18 & over)

Ive been asked hella times to do this video …so i finally got it done , my bad on lagging !
The first time i saw someone roll one of these in person I was shocked…it looked sooo damn hard and he did it like nothing !

Ive messed up soo many cross joints , so if you don’t get it rolled right don’t be discouraged ….. we all start somewhere !

I wanna say thank you to everyone watching , liking and subscribing …you guys seriously make my effin day !!

I’m doing the 100K video this week and I promise its worth the wait ….its gunna be EPIC !!!

Thank you guys so much for watching How To Roll A Cross Joint

Joint Classification: Structural versus Functional

Week 1 Overview on Structural and Functional Classification of Major Joints of the Extremities, discussed in ANATSC 2200 Functional Human Anatomy at the University of Adelaide.

Joints & Joint Movements | Skeletal System 05 | Anatomy & Physiology

This video teaches about the bones that form important #synovial joints in the human body including the shoulder, elbow, wrist, hip, knee and ankle. I then explain a range of joint movements that are possible at these joints and other joints in the body.

I explain all of these movements: #flexion, #extension, dorsiflexion, plantarflexion, lateral flexion, horizontal flexion and horizontal extension, hyperextension, abduction, adduction, horizontal abduction and adduction, rotation, circumduction.

This lecture video discusses the way in which rocks deform and change shape under stress by folding, faulting, and forming joints. I cover the types of faults (dip-slip and strike-slip), the types of folds (anticline and syncline), and the features along faults and folds, like shutter ridges, sag ponds, fault-formed springs, and pop-up structures. I hope you enjoy it!
