Bone joints

• Fibrous ( syndesmosis ): connected by connective tissue. More represented in animals, in humans - ligamentum sacroiliacum interosseum.
• Cartilaginous ( synchondrosis ): intervertebral discs .
• Bone ( synostosis ): the bone has completely grown together ( pelvis , sacrum ).

Also called intervertebral joints, sagittal cuts .

• The body of the vertebra . (Corpus vertebrae)
• Posterior longitudinal ligament (lig.longitudinale posterior). Functions:

1) Connects the posterior surfaces of intervertebral discs and vertebral bodies.

2) Is the front wall of the spinal canal.

3) At the level of the 3rd cervical vertebra, it passes into the integumentary membrane.

• Fibrous ring. (Anulus fibrosus)
• The gelatinous nucleus. (Nucleus pulposus)
• Intervertebral discs, or spinal synchondrosis. (Disci intervertebralis) / (synchondroses columnae vertebralis)
• Anterior longitudinal ligament. Functions: Connects the front surfaces of the vertebral bodies.

• Pubic symphysis
  • Fibrous-cartilaginous structure between the pubic bones.

In the upper part contains a slit-like cavity.

In the joint emit:

• Main elements:
  • The articular surfaces of the bones covered with cartilage ,
  • the articular capsule itself,
  • articular cavity inside it;
  • synovial fluid .
• Additional education:
  • discs, menisci
  • articular lip
  • villi.
