Question

Which of these forms the wrist joint along with the styloid process of radioulnar?
A)Trapezium, trapezoid, capitate and hamate
B)Scaphoid, lunate, triquetrum and pisiform
C)Talus, cuboid, cuneiform and calcaneus
D)Both A and B

Answer 1

A joint is a sort of relation that connects the skeletal system into a functional whole between the bones in the body. They are designed to encourage varying degrees and styles of movement to take place.

Complete answer:
The unla has a styloid process which is found at the posterior point part of the forearm that projects from the medial and posterior part. Carpal bones present in hand are as follows:
Distal: 5. Trapezium, 6. Trapezoid, 7. Capitate, 8. Hamate.
Proximal: 1. Scaphoid, 2. Lunate, 3. Triquetrum, 4. Pisiform.

Joints may also be technically categorized according to the form and degree of motion they allow: With reference to the specific anatomical planes, joint motions are defined.
Synarthrosis-allows little or no movement. The fibrous joints in most synarthrosis joints are (e.g., skull sutures).
Amphiarthrosis-allows moderate mobility. The cartilaginous joints in most amphiarthrosis joints are (e.g., intervertebral discs).
Synovial joint (also referred to as diarthrosis)-freely mobile. In turn, synovial joints can be divided into six categories according to the form of movement they allow: plane joint, ball and socket joint, hinge joint, pivot joint, condyloid joint and saddle joint.

Hence, the correct answer is option (D)

Note: A common "wear and tear" condition is a degenerative joint disease, also known as osteoarthritis (OA). Usually, chronic repetitive motion, which results in inflammation and structural joint damage, is the root cause of this disease. Pressure, redness and swelling are caused by inflammation.
