Connect between vertebra

• Connect between vertebral body – intervertebral disc (fibrocartilage disc) – Anterior longitudinal ligament – Posterior longitudinal ligament • Connect between vertebral arch – ligamenta flava 黄韧带 – interspinal ligament – Supraspinal ligament 脊上韧带 vertebral arch Inter vertebral discs

• Between adjacent vertebrae from 1st to sacrum there are inter vertebral discs. They are fibro-cartilaginous. • The disc permits various movement of the vertebral column, absorb shock and form a strong joint. Connect of the skull

Fibrous joint (Sutures) Articulation -- Temporomandibular joint (TMJ) Mandible Temporal Disc Sutures Fontanels Fontanels

In the skull of the fetus there are 6 prominent fontanels: a) The Anterior (frontal) fontanel, between angle of two parietal bones & the frontal bone. It is diamond shaped and is the largest fontanel. It closes 18 to 24months after birth. b) The posterior (occiputal) fontanel, between parietal & occiputal bone. It is also diamond shaped but smaller than the anterior fontanel. It closes 2 months after birth. Fontanels c) The Antrolatral (sphenoidal) fontanel, paired, one in each side. Found at the junction of frontal, parietal, temporal & sphenoidal bone. They are small & irregular in shape and closes at 3rd month after birth. d) The postrolateral (mastoid) fontanel, Paired one in each side. Found at the junction of parietal, occiputal and temporal bones. They are irregular in shape and begin to close at 1 or 2 months after birth and completed by 12 months. Temporomandibular joint
