A ganglion lump attached to ligaments is a ganglion cyst. The cyst is a ball of fluid that grows on a ligament, tendon, or joint. Most go away in time by themselves, but some need surgery or needle aspiration.
The thumb is made up of two phalanges (one distal phalanx and one proximal phalanx), and one metacarpal. At the "visible base" of the thumb, or where the thumb seems to enter the hand, there is a condyloid synovial joint, which involves the articulation of the proximal phalanx on the first metacarpal. The TRUE base of the thumb is where the first metacarpal articulates with the trapezium (a carpal bone of the hand). This joint is a saddle-type synovial joint.
The base of the thumb, the first phalanx, makes a joint with a carpal bone called the trapezium, and the two articulate in a special joint called a saddle joint. You only have tow of these in your body, one at the base of each thumb.
The long thin tendon commonly used for tendon transplants is the flexor tendon from the hamstring muscle, known as the "semitendinosus" tendon.
Trapezium or Greater Multangular Trapezoid Carpal. Proximal to this is the Scaphoid or Navicular Carpal.

A lump between the thumb and index finger could be a ganglion cyst, which is a noncancerous swelling filled with fluid. It can be painful and may restrict movement. It is best to have it evaluated by a healthcare provider for proper diagnosis and treatment.
The joint located at the base of the thumb is called the carpometacarpal joint.
Often when a body part is numb and immobile, it is because there is tendon damage. My arm went through a window a few years back, I lacerated the tendon in my thumb. 90% of it was cut and it was not only almost impossible to move, but was completely numb before the surgery.
The curve of your thumb is the part where it looks rounded, at the base of your thumb.
A small firm lump under your skin at the base of your penis could be a cyst, but this should be confirmed with a doctor.
