Pivot joint: A rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament . The bone rotates within this ring. Since the rotation is around a single axis‚ pivot joints are functionally classified as a uniaxial diarthrosis type of joint. An example of a pivot joint is the atlantoaxial joint‚ found between the C1 (atlas) and C2 (axis) vertebrae. Here‚ the upward projecting dens of the axis articulates with the inner aspect

If one didn’t have the ability to joint two pieces of wood together in a solid fashion‚ all woodworking pieces would be sculptures‚ carved out of a single piece of wood. However‚ with the many varied types of wood joinery‚ a woodworker has a number of different joints in his arsenal from which to choose‚ based upon the project. If you master these wood joinery concepts‚ you’ll be well on your way to becoming a very accomplished woodworker. 1. Basic Butt Joint (c) 2009 Chris Baylor licensed to

Introduction The knee is one of the largest and most complex joints in the body. The knee joins the femur to the tibia. The smaller bone that runs alongside the tibia is the fibula. The patella‚ also known as the knee-cap‚ is another one that makes up the knee joint. I decided to discuss this joint structure because of reoccurring knee injuries. The Knee Joint The knee joint is formed by the articulation of the distal end of the femur and the proximal end of the tibia. The fibula

BY JACOB WOODS 12G Synovial Joints Synovial joints are characterised by a layer of synovial fluid surrounding the articulating surfaces. This helps to lubricate the cartilage therefore reducing the friction between the joints. The synovial capsule stores the fluid‚ meaning it can lubricate the joint quickly. There are 5 types of synovial joint. They are as follows. Ball and socket joint Spheroidal joints to give them their technical name are joints that include two articular surfaces; a ball

A joint is defined as a fracture in a rock between the sides of which there is no observable relative movement. They are present is most consolidated rocks of igneous‚ metamorphic and sedimentary origin. Joints may form as a result of either diastrophism or contraction. Description: (i) A series of parallel joints is called a ’joint set’. (ii) Two or more joint sets intersecting each other produce a ’joint system’. (iii) Two sets of joints nearly at right angles to one another‚ produced by the

Types of joints: Ball-and-socket joint: Consists of a bone with a globular or slightly egg-shaped head that articulates with the cup-shaped cavity of another bone. Such a joint allows a wider range of motion than does any other kind‚ permitting movements in all planes‚ as well as rotational movement around a central axis. The hip and shoulder contain joints of this type. Condyloid joint: The ovoid condyle of one bone fits into the elliptical cavity of another bone‚ as in the joints between the

Temporomandibular joint (TMJ) is the hinge joint that connects the lower jaw mandible to the temporal bone of the skull ‚ which is immediately in front of the ear on each side of your head . The joints are flexible‚ allowing the jaw to move smoothly up and down and side to side and enabling you to talk‚ chew ‚ and yawn . Muscles attached to surround the jaw joint control the position and movement of the jaw . A treatment method for the temporomandibular joint (TMJ) is aimed to clarif
