What are rheumatoid nodules?
A rheumatoid nodule is a firm feeling swelling or lump which occurs within 2 years in about 5% of people once they are diagnosed with rheumatoid arthritis. And about 25% of RA victims wil get them at some time during their lives. It is very unusual for 'rheumatoid nodules to appear if not accompanied with arthritis. They are usually subcutaneous ( under the skin) especially over bony prominences such as the tip of the elbow or over the knuckles. they can also appear in the lining of the lungs as well as other organs. Sizes of Nodules vary from that of about a pea to that of a small orange. Quite often they are associated with synovial pockets or bursae. Generally rheumatoid nodules are not painful or in any way disabling, Unless they are on a place where there is a lot of contact such as on the back of the arm under the elbow where people tend to rest their arms when doing desk work an similar situations. Other then that they are just not very attractive. In isolated cases they can appear on parts of the body such as the upper eyelid, distal region of soles, vulva and internally in the gallbladder, lung, heart valves, larynx and spine.Rheumatoid nodules consist of a shell of fibrous tissue surrounding a centre of fibrinoid necrosis. Pea sized nodules have one centre. Larger nodules tend to be multilocular, with many separate shells or with connections between the necrotic centres. Individual necrotic centres may contain a cleft or several centres of necrosis may all open on to a large bursal pocket containing synovial fluid. The boundary between the necrotic centre and the outer fibrous shell is made up of the characteristic feature of the nodule, which is known as a cellular palisade. The palisade is a densely packed layer of macrophages and fibroblasts which tend to be arranged radially, like the seeds of a kiwi fruit or fig. Further out into the fibrous shell there is a zone that contains T lymphocytes and plasma cells in association with blood vessels. The overall histological picture is essentially identical to that of rheumatoid synovitis with the main differences being that the palisade replaces the synovial intima (they may blend imperceptibly in bursae) and an almost total absence of B lymphocytes.(Sourced from Wikipedia)
What is the name tooth distal to J in mixed dentition model?
Left Maxillary 1st molar.
What makes a joint a distal interphalangeal joint?
A distal interphalangeal joint is the articulation of the medial and distal phalanges. In contrast, a proximal interphalangeal joint is the articulation of the proximal and medial phalanges.
What synovial joint is an interphalangeal joint?
Proximal and distal interphalangeal joints.
What is the name of the most distal joint of the lower extremity?
The distal interphalangeal joints are the most distal joints of the lower extremities.
What are the names of the parts of the index finger?
From the nail down the distal phalances, distal interphalangeal joint, the middle phalanges and then the proximal interphalangeal joints. The base of the finger is comprised of the proximal phalanges and the knuckles.
What muscle flexes the distal interphalangeal joints?
The flexor digitorum profundus
The only muscle capable of flexing the distal interphalangeal joints?
Flexor digitorum profundus
What joints are distal to the ankle?
Subtalor, Talo-calcaneo-navicular, tarso-metatarsal, Metatarsophalangeal, Interphalangeal joints
What joint do the proximal and distal phalanges meet at?
The proximal and distal phalanges only meet in the first digits (the thumbs and the big tues). This joint is the first interphalangeal joint.
What muscles are used in firing a pistol?
There would be 2 muscles involved in pulling the trigger: 1 - Flexor digitorum superficialis - flexes the proximal interphalangeal joint 2 - Flexor digitorum profundus - flexes the distal interphalangeal joint
How many interphalangeal joints are in the hand?
Simply put, there are nine (9) interphalangeal joints in the hand. The hand consists of 5 digits numbered 1-5 from thumb to "pinkie". Digit 1 (thumb) has two phalanges one called the proximal phalanx and another called the distal phalanx. So, there is one interphalangeal joint between the proximal and distal phalanges of the thumb. Digits 2-5 each has three phalanges a proximal phalanx, a middle phalanx and a distal phalanx. So, each digit has 2 interphalangeal joints.
What is the name of the knuckle joint?
The interphalangeal joints in the fingers are synovial hinge joints. The thumb metacarpal is a saddle joint. The metacarpo-phalangeal joints are synovial ellipsoid joints.
What sesamoid bone forms in the quadriceps tendon?
Sesamoid bones are also found occasionally at the metacarpophalangeal joints of the middle and ring fingers, at the interphalangeal joint of the thumb and at the distal interphalangeal joint of the index finger. In the lower extremity the largest sesamoid bone of the joints is the patella, developed in the tendon of the Quadriceps femoris.
