Types of Joints in the Neck

ARTHROLOGY

IS

JOINTS

It defines the joint ,as all soft and hard parts, througth which two or more bones meet next.

The formal study of the anatomy, physiology, derangements and management of joints and articulations; the term’s use is waning in the working medical parlance.

are classified in

CARTILAGINOUS JOINTS

JOINT SYNOVIAL

FIBROUS JOINTS

This type of joint is held between the cartilage and bone, do not allow both motion

are divided into

These joints move freely, are classified from a functional standpoint as diartrosis and are characterized by the presence of articular cartilage that covers the surfaces of the bones of the joint, is a hyaline cartilage

No joint cavity.

United by fibruos connective tisuue.

CARTILAGINOUS JOINTS PRIMARY OR SYNCHONDROSES:

Rict perspective, there occurs between bones, but the roots of the teeth and the alveoli of the upper and lower jaws.

Allows only very limited movement.

Are located between the bones of the skull

held together by layers of fibrous tissue or ligaments .

limited movement and in adults are considered immobile or sinartrodiales.

The only syndesmotic tibioperobea distal joints. The distal ends of the tibia and fibula ( fibula ) are attached to this joint by fibrous ligaments.

Not mobile.

They are passing joints between bones by cartilage, as the joints between parts of a growing bone

• Hyaline cartilage

• Very low mobility

• Are lost to development.

THOCHLEAR JOINTS

SECONDARY CARTILAGINOUS JOINTS OR SYMPHYSIS

THOCHOID JOINTS

• Phones: also called synovial or synovial joints are having greater range of motion. They are what bind bones of the limbs to the trunk, shoulders or hips.

capsules

The articular capsule is composed of two layers:

1. The (outer) fibrous capsule, which consists of dense connective tissue (collagen).

2. The synovial membrane, composed of loose connective tissue in elastic fibers and varying amounts of adipose tissue.

• Articular Cavity: bone surface concave part of a synovial joint.

• Articular cartilage: Articular cartilage is a layer covering the surface of the joint, and it has the functions of serving as a buffer and reduce friction or rubbing when you move the limb.

• "complex" Structure

• Ancillary Structures

A point surface fits into a ring of a bone and ligament, allowing a rotation around ist own longitudinal axis

Example:

- Radioulnar

- The same

They are slightly movable joints and definitive cartilage between two bones by a very robust cartilage.

• Fibrocartilage

• Very mobile

• Permanent.

RECIPROCAL FIT JOINTS

Is similar to condylar due to allows the same movemets on the same axes, but her motion is a little more limited

Example:

- Carpal trapeziun

- First metacarpal

Condylar articulation

CONDYLAR JOINTS

In the knuckle with a surface oval convex is projected with a bone that fits in an oval depression of another bone of type biaxal because two axes move

Example:

-Radiocarpal

-Fith finger

Articular surfaces take the convex elipsoidal

Spheroidal joint

Allows a very wide range of movement: abduction adduction and flexion-extension rotation.
