What is the fovea of the radius?

What is the fovea of the radius?

the concave superior surface of the head of the radius that articulates with the capitulum of the humerus.

What structure interacts with the articular fovea of radius?

The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.

What is the function of radius?

The radius’ main functions are to articulate with the ulna and humerus at the elbow to provide supination and pronation. Then to articulate with the lunate and scaphoid to provide all the movements of the wrist.

What does head of radius articulate with?

The radius articulates proximally at the elbow with the capitulum of the humerus and the radial notch of the ulna. It articulates at its distal end with the ulna at the ulnar notch and with the articular surfaces of the scaphoid and lunate carpal bones.

What is the fovea and why is it important?

It is located in the center of the macula lutea of the retina. The fovea is responsible for sharp central vision (also called foveal vision), which is necessary in humans for activities for which visual detail is of primary importance, such as reading and driving.

How does the fovea work?

Fovea: In the eye, a tiny pit located in the macula of the retina that provides the clearest vision of all. Only in the fovea are the layers of the retina spread aside to let light fall directly on the cones, the cells that give the sharpest image. Also called the central fovea or fovea centralis.

What is the articular facet of head of radius?

What is the function of Humeroulnar joint?

The humeroulnar joint, is part of the elbow-joint or the Olecron Joint, between the ulna and humerus bones is the simple hinge-joint, which allows for movements of flexion, extension and circumduction. The Humero-Ulnar Joint is the junction of trochlear notch of the ulna and the trochlea of the humerus.

Where is radius protocol used?

RADIUS stands for Remote Authentication Dial-In User Service, is a security protocol used in the AAA framework to provide centralized authentication for users who want to gain access to the network.

How many articular surfaces does the head of radius have?

two articular surfaces
Near the wrist The distal end of the radius is large and of quadrilateral form. It is provided with two articular surfaces – one below, for the carpus, and another at the medial side, for the ulna.

What is the function of the ciliary body in the eye?

The ciliary body is found behind the iris and includes the ring-shaped muscle that changes the shape of the lens when the eye focuses. It also makes the clear fluid that fills the space between the cornea and the iris.
