Which joint is in the distal end of the radius with the carpal bones of the wrist?

Scaphoid and lunate. Probably part of the triquetrum also. Distal end of ulna does not take any important part in articulation with the wrist bones.

Why are there eight short bones forming the wrist?
It is the lower end of the radius bone taking part in wrist joint. Actually three bones are attached to radius bone. Scaphoid, Lunate, Triquartal. Forth Pisiform is a sesmoid bone. So you require first row of small bones, so that movement should be possible between radius and bones. With single bone attached to radius movement would have been restricted. Next row of four bones is attached in order to have more mobility to the metacarpals in one hand and proximal row of bones in other hand. It is possible to have four bones attached to proximal row to expand the area of movement. Here again with single long bone, movements have been restricted. As you have to support five fingers there should have been five small bones. But 'Nature' found it prudent to attach four bones to proximal three bones and attach five metatarsals to distal carpal bones. Here joint has to be flat and so many carpal bones are there. Here you have flex-ion, extension, adduction, abduction and circumduction. This joint is one of the architectural marvel by 'Nature'.
What joint is found between the humerus and the ulna?
A strong, complex ligament called the inter- (between) -osseous (bones) ligament, plus some blood vessels and nerves. You can find these things in the center of the forearm, between the two bones. Strong ligaments also connect the radius and ulna down by the wrist and up by the elbow.
What two bones compose the antebrachium?
The radius and ulna are the two bones that make up the antebrachium.
How do you build an elbow joint?
Three bones form the elbow joint: the Humerus of the upper arm, and the paired Radius and Ulna of the forearm.
Which two bones rotate over your wrist?
Radius and Ulna are the two bones which rotates over your wrist joint. In this radius rotates over ulna. The actions are called as Pro-nation and Supination.
Which bones are next to the carp joint?
The carpus or carpal joint is the wrist. The proximal bones are those of the forearm: the radius and ulna. The distal bones are those of the palm: the metacarpals.
Does the wrist joint consist of the ends of the radius and ulna bones of the forearm with the carpal bones of the hand?
No, ulna share not in the formation of the wrist joint. The joint is formed between distal end of radius with scaphoid and lunate. And articular disc of wrist with triquetral.
Which carpal bone can be palpated as a projection distal to the styloid process of the ulna?
The styloid process of the Ulna (one of the bones of the forearm) is where the Ulna connects to the ligament of the wrist joint. The Triquetrum, Lunate and Pisiform carpal bones all lie distal to this. However the carpal bone most easily palpable is the Pisiform bone.
What type of joint is at the navicular radial joint?
The navicular bone is sometimes referred to scaphoid bone, which is one of the carpal bones in the wrist. It is also called the radiocarpal joint when it is associated with th radius and the lunate, another carpal bone. The three bones the form an ellipsoidal joint.
Which forearm bone allows us to rotate the wrist?
There are 8 small bones in wrist joint.Proximalrow contains (From lateral to medial side.) ScaphoidLunateTriquartal and Pisiform bones. Except Pisiform other three are attached to lower end of 'Radius' bone. Please note that in 'elbow' joint Ulna bone takes part and in wrist joint charge is handed over to Radius bone. Distal row contains Trapezium, Trapezoid, Capitate and Ham-mate. So if you ask about the single bone, then the answer is Radius and not Ulna bone. But please remember that 'single' bone can not form a joint. There has to be at-least two bones. Here lower end of Radius comes in contact with three bones. Scaphoid, Lunate and Triquartal bones. Pisiform is a sesmoid bone. On distal side there are carpal-metacarpal joints. There are 5 metacarpals attached to four carpal bones.
Is distal radius and ulna type of syndesmosis joint?
The radius and ulna are joined by a syndesmosis along the lengths of their shafts. The distal radioulnar joint is not a syndesmosis.
Is the radius medial to the ulna?
No. The radius is distal to the humerus. The humerus is proximal to the radius. :D
How many bone is in the Thumb?
There are four bones in the thumb. one at the top one at the bottom and one at either side.The bones in the thumb consist of: distal phalanx; proximal phalanx; metacarpal; carpal bones (carpometacarpal joint (CM).
Is elbow proximal the wrist?
No. The wrist is DISTAL to the elbow. The radius and the ulna ( your forearm ) are what separates the elbow joint from the carpals, and the metacarpals, which is your wrist.
What type of joint is carpal-carpal?
The joints between the carpal bones in the ankles and wrists are known as Gliding Joints (a type of synovial joint). These joints work by allowing the bones to slide over each other, allowing smooth movements in multiple directions.

Joint connecting foot and leg?
The talocrural joint connects the foot with the leg. The bones that make up this joint are the talus, distal fibula, and distal tibia.
