The upper surface of the cylindrical head of the radius is spherically concave to fit the capitulum. The upper end of the ulna shows the deep trochlear notch. There are commonly two separate articular surfaces in the trochlear notch, one on the olecranon and the other on the coronoid process.Furthermore, what does the Trochlear notch do?
The trochlear notch (semilunar notch, greater sigmoid cavity) is a large depression, formed by the olecranon and the coronoid process, and serving for articulation with the trochlea of the humerus.
Similarly, where is the Trochlea located? trochlea: At the distal head of the humerus, it articulates with the ulna of the forearm.
Accordingly, what two structures form the trochlear notch of the ulna?
The trochlear notch (also semilunar notch, or greater sigmoid cavity) is a large depression in the upper extremity of the ulna that fits the trochlea of the humerus (the bone directly above the ulna in the arm) as part of the elbow joint. It is formed by the olecranon and the coronoid process.
What articulates with the radial notch of the ulna?
The proximal end of the ulna articulates with the trochlea of the humerus. Radial notch – located on the lateral surface of the trochlear notch, this area articulates with the head of the radius. Tuberosity of ulna – a roughening immediately distal to the coronoid process.
What bone articulates with the trochlear notch?
humerus
Where is the Coronoid process located?
The coronoid process is a triangular eminence projecting forward from the upper and front part of the ulna. Its base is continuous with the body of the bone, and of considerable strength. Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus.What is notch anatomy?
notch. [noch] an indentation, especially one on the edge of a bone or other organ; called also incisure.Where is the radial notch?
The radial notch is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius. It is concave from before backward, and its prominent extremities serve for the attachment of the annular ligament.Where is the ulnar notch?
The ulnar notch is a concave articular hollow on the medial corner of the distal radius. It articulates with the distal end of the ulna.What type of joint is the elbow?
hinge joint
What is the olecranon process?
1. olecranon process - process of the ulna that forms the outer bump of the elbow and fits into the fossa of the humerus when the arm is extended. olecranon. appendage, outgrowth, process - a natural prolongation or projection from a part of an organism either animal or plant; "a bony process"What is the femoral Trochlea?
Description. The trochlea of femur (femoral trochlea) is the cranial cartilaginous part of distal femur, for articulation with the patella fo form the femoral patellar joint. It consists of a groove bounded by the medial and a lateral ridges.What is ulna bone?
The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm. It runs parallel to the radius, the other long bone in the forearm, and is the larger and longer of the two.What is carpal bone?
The carpal bones are the eight small bones that make up the wrist (or carpus) that connects the hand to the forearm. The term "carpus" is derived from the Latin carpus and the Greek καρπός (karpós), meaning "wrist". The carpal bones allow the wrist to move and rotate vertically.What does the ulna look like?
Ulna. Ulna, inner of two bones of the forearm when viewed with the palm facing forward. The upper end of the ulna presents a large C-shaped notch—the semilunar, or trochlear, notch—which articulates with the trochlea of the humerus (upper arm bone) to form the elbow joint.What is the function of the capitulum?
In human anatomy of the arm, the capitulum of the humerus is a smooth, rounded eminence on the lateral portion of the distal articular surface 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 the difference between an epicondyle and a condyle?
Epicondyle is a projection on the condyle. The main difference between condyle and epicondyle is that condyle forms an articulation with another bone. whereas epicondyle provides sites for the attachment of muscles.Where is the olecranon process located?
ulna
What does the olecranon fossa articulate with?
The olecranon fossa of the humerus articulates with the olecranon process of the ulna. How do you side a scapula? To side a scapula, first locate the spine of the scapula (located on the posterior surface of the scapula).Is the ulna on the inside or outside?
The ulna is located on the opposite side of the forearm from the thumb. It joins with the humerus on its larger end to make the elbow joint, and joins with the carpal bones of the hand at its smaller end. Together with the radius, the ulna enables the wrist joint to rotate.Where is the radius?
Radius (bone) The radius (shown in red) is a bone in the forearm. The radius or radial bone is one of the two large bones of the forearm, the other being the ulna. It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna.
