Introduction

Developing distal phalangeal joint

In the adult, the region where two skeletal bones meet and articulate is called a "joint", that are classified based upon their: anatomical structure, mobility and shape.

In the embryo, the majority of the vertebrate skeleton is initially formed as a cartilage template, that is later replaced by bone except at the interface between two adjacent bones, leaving in the adult a layer of cartilage in this region. The musculoskeletal system consists of skeletal muscle, bone, and cartilage and is mainly mesoderm in origin with some neural crest contribution.

Some Recent Findings

  • Analysis by Light, Scanning, and Transmission Microscopy of the Intima Synovial of the Temporomandibular Joint of Human Fetuses during the Development[1] "To characterize morphologically and ultrastructurally using light microscopy, the scanning electron microscopy and transmission electron microscopy the intima synovial of the temporomandibular joint (TMJ) of human fetuses between the 10th and the 38th week of development. Materials and Methods. The TMJ was dissected bilaterally in 37 human fetuses belonging to the Institute of Embryology of the University Complutense of Madrid and of the Federal University of São Paulo. Results. The outcome by light microscopy showed the morphology of the TMJ and that the formation of inferior joint cavity precedes the superior joint cavity and the presence of blood vessels in the synovial.

Joint Types

Joint development 02.jpg

Classification

  • Fibrous (synarthrodial) - immoveable joints found in cranial vault and teeth
  • Cartilagenous (synchondroses and sympheses) - partially moveable joints
  • Synovial (diarthrosis) - freely moveable joints are the most common found in the skeleton

Movement

Mouse neck joint articular cartilage. Cartilage Histology
  • Hinge - (elbow and knee) Flexion/Extension
  • Pivot - (neck, atlas and axis bones) Rotation of one bone around another
  • Ball and Socket - (shoulder and hip)
  • Saddle - (thumb)
  • Condyloid - (wrist joints)
  • Gliding - (intercarpal joints) Gliding movements
