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

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

The groin muscles, called the adductor muscle group, consists of six muscles that span the distance from the inner pelvis to the inner part of the femur (thigh bone). These muscles pull the legs together, and help with other movements of the hip-joint. The adductor muscles are important to many types of athletes including sprinters, swimmers, soccer players, and football players. A groin pull is an injury to the adductor muscles called a muscle strain. When a muscle is strained, the muscle is stretched

Ulnar Collateral Ligament Injury of the Thumb A ligament is a strong band of tissue that connects and supports bones. Ulnar collateral ligament (UCL) injury happens when the UCL at the base of the thumb is stretched or torn. A tear can be either partial or complete. The severity of the injury depends on how much of the ligament was damaged or torn. The UCL ligament is important for normal use of the thumb. This ligament helps you use and move your thumb. . UCL injury can happen suddenly (acute

the ACL prevents the knee joint from moving during quick changes in movement. Pivoting and cutting are the most common movements that cause the ACL to rupture.1 ACL tears were found to be the knee’s most commonly diagnosed sports injury, and the protocol is reconstructive surgery.2 The rehabilitation process begins shortly after surgery. Standard rehabilitation has been based around strength building exercises like: leg press, hamstring curls, and leg extensions. Knee joint flexibility

I have 3 long-term sports injuries...all in my legs. I have planters fasciitis, Osgood Schlatters and I was born with loose ligaments in my legs. The Lateral Collateral ligaments in my legs are loose, apparently it’s very rare. This was a turning point in my life because it showed me how much harder I have to work if I want any type of sports career, I found out I had these 1 by 1. I started to notice big bumps under my knee caps and it looked like I got hit with something and it started to swell

group of muscles around your shoulder that are attached by tendons to the joint allows your arm to move and keeps the shoulder stable. These muscles and tendons form the rotator cuff. Injury to the tendons may cause swelling and pain due to rotator cuff tendinitis, or a rotator cuff tear, which is often associated with injury or overuse. Torn rotator cuff exercises can help improve your symptoms and restore shoulder joint function. Part 1: Torn Rotator Cuff Exercises Rotator cuff injuries often lead

Abstract— The main aim is to develop the three dimensional solid finite element model of knee joint to predict stress in its individual components (Femur, Tibia, Menisci and Patella) and to determine the load carried by a pre – selected ligamentous tissue. This work assists to analyze a knee response to a dynamically applied load. This simulated analysis will serve to be an alternative approach to destructive tests and intrusive procedures and helps to achieve closer simulation to reality. The main

Abstract: A meniscus is a piece of cartilage found where two bones meet. This joint space distributes loads to protect the articular cartilage of the knee joint from too much stress. Injuries to these regions increase the risk for knee osteoarthritis, can disrupt regular function, and do not heal. The goal of meniscus tissue engineering is to use regenerated tissue in order to restore the normal function of the meniscus. The main purpose of this study is to design 3D scaffolds that can maintain the

“medial collateral ligament.” This is one of the ligaments of the knee, a thick band of connective tissue located at the medial (or inner) side of the knee which protects and stabilizes your knee joint, and allows it to rotate. Though your medial collateral ligament functions to protect your knee joint, it is also one of the most commonly injured part of your knee; hence, sustaining an MCL injury. Understanding MCL Injury and Its

The Achilles tendon is a band of fibrous tissue that connects the calf muscles to the heel bone. The two-calf muscles that attaches to the heel bone are the gastrocnemius and soleus. The Achilles tendon lower part of the calf that attaches to the calcaneus. The Achilles tendon allows to stand, run, or jump while being on our toes. While doing any movement the calf muscles flex and pull on the heel. With the lack of blood supply, the tendon is more susceptible to injury. Achilles tendinitis most
