Where is the Radiohumeral joint?
the elbow
The three joints of the elbow include: Ulnohumeral joint is where movement between the ulna and humerus occurs. Radiohumeral joint is where movement between the radius and humerus occurs. Proximal radioulnar joint is where movement between the radius and ulna occurs.
What makes up the Radiohumeral joint?
The proximal radioulnar joint is a synovial joint that connects the proximal ends of the radius and ulna. In this joint, the circumferent head of radius is placed within the ring formed by the radial notch of ulna and the annular ligament. This configuration makes this joint a pivot joint.
What is the Ulnotrochlear joint?
Ulnotrochlear joint – This joint, which is between the olecranon process of the ulna and the medial condyle of the humerus, is a constrained joint that allows only flexion and extension.
What is the Radiocapitellar joint?
The radiocapitellar joint is where the humerus and the radius meet, allowing for rotation of the forearm so that the hand can be turned palm up or palm down. The radial head is the knobby end of the radius that rotates around the ulna.
What is humeroradial joint?
The humeroradial joint is formed between the radius and humerus and allows movements like flexion, extension, supination, and pronation. The radioulnar joint is formed between the ulna and radius bones and allows rotation of the lower arm.
What is elbow joint called?
The elbow joint is classified structurally as a synovial joint. It is also classified structurally as a compound joint, as there are two articulations in the joint. Synovial joints, also called diarthroses, are free movable joints….Elbow joint.

What is capitellum?
: a knoblike protuberance especially at the end of a bone (as the humerus)
What are Intercarpal joints?
The intercarpal joints are the synovial plane joints that connect the carpal bones. They gather three sets of joints; Joints of the proximal carpal row, that connect the adjacent surfaces of the scaphoid, lunate and triquetrum bones.
Why is it called tibiofemoral joint?
The main weightbearing part of the knee joint is made up of the articulation between the tibia and femur. This is called the tibiofemoral joint. On the inner side is the medial tibiofemoral compartment and on the outer side is lateral tibiofemoral compartment.
What bone is the capitellum?
humerus
The lateral portion of the articular surface of humerus consists of a smooth, rounded eminence, named the capitulum of the humerus; it articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.
What is Humeroradial joint?
Is the Intercarpal joint a pivot joint?
Examples include intercarpal joints, intertarsal joints, and the acromioclavicular joint. A pivot joint is an articulation within a ligamentous ring between the rounded end of one bone and another bone. This type of joint is uniaxial because, although the bone rotates within this ring, it does so around a single axis.
