Dental Abscesses and Infection in Gums: What You Need to Know. You're relaxing after a day at work or spending time with your family when you feel a sharp pain in your mouth. If you have a history of dental problems â such as infection in gums, teeth or even cavities â the pain could be related to a dental abscess. There are two types of dental abscess: A periapical, or tooth abscess, affects the root of the tooth. The other type, a periodontal (gum) abscess, affects the gums.
The upper extremity is a term used to define the upper limb. This includes the shoulder, arm, forearm, wrist and hand. The hand is a very complex part of the body, and all of the parts of the upper extremity are essential to functioning hands. Within the upper extremity, there are bones, joints, muscles, nerves, vessels and tendons that tie all of the parts together.
The upper limb is divided into three regions. These consist of the arm, located between the shoulder and elbow joints; the forearm, which is between the elbow and wrist joints; and the hand, which is located distal to the wrist. There are 30 bones in each upper limb (see [link]).hese bones lie between the carpal bones of the wrist and the bones of the fingers and thumb (see [link]). The proximal end of each metacarpal bone articulates with one of the distal carpal bones. Each of these articulations is a carpometacarpal joint (see [link]).
