Synovial joint Essays

1. INTRODUCTION: The malady trigger finger earns its name from the painful popping or clicking sound elicited by flexion and extension of the involved digit. First described by Notta in 1850 [1], it is caused by a difference in diameters of a flexor tendon and its retinacular sheath due to thickening and narrowing of the sheath. Though often referred to as stenosing tenosynovitis [2]. Several causes of trigger finger have been proposed, though the precise etiology has not been elucidated. Understandably

The hip is a true ball and socket joint and the arrangement gives the hip the large amount of motion needed for daily activities like walking, squatting and stair climbing. The bones that form the hips are the femur or far bone and pelvis. The top of the femur shape like a ball called femoral head that fits into a round socket on the side of the pelvis. This socket is named as acetabulum. The femoral head is attached to the rest of the femur by a short section of a bone called femoral neck. A large

Synovitis, an inflammation of the synovial membrane, is a common injury that affects many horses, especially those in heavy work or competition, and if not treated quickly can have severe consequences for the future wellbeing and soundness of the horse. It often occurs in conjunction with Capsulitis, which is inflammation of the joint capsule. To understand Synovitis, a basic understanding of a synovial joint is required. A synovial joint is any moveable connection between two bones. Some of the

Elbow joint replacement Probably the most used joint besides knees are probably elbows. The elbow joint is primarily used to help position, and rotate the the arms, and hand. With that, primarily over the years the wear and tear of the ligaments, and bone structure of the three bones (Humerus, Radial, and Ulna) can lead to Osteoarthritis. Osteoarthritis is a degenerative joint disease that is caused from the ages around fiftey.. The wear and tear part comes in when the cartilage that houses the

Keep Your Knees Healthy and Strong with the Help of the Following Ten Tips The largest joints in the human body are the knees. The knees provide the legs with stability, flexibility and support that it needs for turning around easily, walking, crouching, standing, jumping and running. This is why it is extremely important to keep your largest joints healthy and strong. With age, knees become weaker, so knee issues are usually a problem of older people. However, people of any age can experience

Typical Adult Anatomy: Bones A fully functioning hip joint is a vital portion of anatomy, from birth to advanced adulthood. The hip is responsible for the stabilization of a person’s body weight whether the person is static or dynamic. The physical joint is classified as a ball-and-socket joint, the head of the femur articulates with the acetabulum of the pelvis. With how the head is oriented in the socket, the joint is able to withstand tremendous amounts of pressure and allows it to be a strong

Arthritis is painful inflammation and swelling of the joints. The term is used to describe around 200 rheumatic diseases and conditions that affect joints (Arthritis Information). The biggest misconception about the condition is that it can be caused by cracking your knuckles. This myth originated from people drawing conclusions without scientific evidence, and just like every other myth or rumor, the false information spread quickly. So if popping your knuckles does not lead to arthritis then what

Introduction The knee joint is most commonly involved in many sports injuries and as modern sport is being more and more competitive, more complex knee injury patterns are being recognized. Anterior cruciate ligament (ACL) is a very commonly involved ligament in these injuries.8 The knee joint is a large compound type of synovial joint. Due to the lack of bony support, stability of the joint is highly dependent on its supporting ligamentous structures, and therefore injuries of

extremity. The forearm consists of two parallel bones, the radius and the ulna. It forms a functional unit that can be considered both as an axis and a non synovial joint (). This “joint” can be best understood in term of two “condyles”, the distal radio-ulnar joint (DRUJ) and the proximal radioulnar joint (PRUJ) (). The capsule of the elbow joint and the annular ligament stabilize the bones proximally. Distally, the bones are connected by a wrist capsule, radio-ulnar stabilizing ligaments (dorsal and

The gross anatomy of human finger nail consists of the following: 1. Nail plate: The nail plate is mainly produced by the matrix which emerges via the proximal nail fold and is held in place by the lateral nail folds. It overlays the nail bed and detaches from the latter at the hyponychium which is the skin under the free edge of the plate. The nail plate has an average thickness of 0.25–0.6 mm. It is hard, yet slightly elastic, translucent, convex and is made up of approximately 25 layers of dead

(Fig. 27) Compared to TKA, unicompartmental arthroplasty results in better knee joint with quicker rehabilitation time and greater range of motion. Revision of UKA to tricompartmental prostheses, requires special components, bone grafting or cement with screw augmentation to fill osseous defects, was necessary in 76% of patients

called as Joint Pain? Overview Yes it is called joint pain. Joints are the connections between the bones and allow any movement that happens in the body. The following are some of the causes of joint pains: strains, sprains, injuries, rheumatoid arthritis, gout and osteoarthritis among many other causes. Soreness of the body joints increase and become common as you increase in age, these pains are said t occur in any part of the body that has a joint. It does not matter the cause of the joint pain, all

that rests between the trochlear groove in front of the Femur (thighbone) and Tibia (shinbone). This moveable bone in front of the knee is referred to as the largest sesamoid bone which is embedded within the tendons that attach muscles to certain joints and its back is lined with the thickest cartilage in the body. It slides up and down in the groove yet edges on either side of the groove, preventing it from moving sideways. Its base is facing proximally and its tip or the Apex Patellae is facing

Temporomandibular Joint is a hinge that connects the upper jaw (bone of the skull) and lower jaw (mandible of the jaw) to one another, it is also responsible for the movement of the jaw side to side, forward, and backwards. The temporomandibular joint is comprised of the outside parts of the mandibular fossae of the temporal bone, other ligaments, and parts of the eminences and mandible. This joint is one of the most complex joints in the human body. You can see a lot of the movement of the joint if you open

associated with an abnormal joint structure and laxity of the muscles, connective tissue (CT) and ligament that normally support the joint. As this joint laxity develops, the articular surfaces on the femur and in the acetabulum loose contact with each other. This separation within the joint is known as a subluxation and will cause drastic changes in both the size and shape of the articular surfaces. All dysplastic dogs are born with normal hips but the soft tissues surrounding the joint develops abnormally

femoral sulcus. Its proximal attachment is the quadriceps tendon which envelopes the structure and distally at the apex, the patellar tendon attaches. Both the tendons are functional as to stabilise the patella bone in the knee joint during movements or even when the joint is static. Also, the patellar retinacula are attached to both the medial and lateral sides of the patella. When the tendon is overused chronically without given adequate time to heal, tendinosis known as Jumper’s Knee can occur

Lab 2: Force Angle relationship 250 words 4 marks In this lab we concentrated on investigating the relationship between joint angle and consequential ability of muscles to produce force. The knee joint was focused on with the quadriceps (rectus femoris, vastus lateralis, vastus intermedialis vastus medialis) and hamstrings (semitendinosus, semimembranosus. biceps femoris lomg head and short head) being the main muscle groups studied. A relationship exists between the length of the muscle before the

over-stretching or tearing of the anterior cruciate ligament ACL in the knee. A tear could be small, or it could be very large in the amount of tearing in the ACL. Three bones meet to form your knee joint, your femur, the shinbone or the tibia, and the patella. Your patella sits in front of the joint to provide some protection. There are four primary ligaments in your knee. Collateral ligaments are found in the side of your knee. The
