General Objective

To recognise bone in histological sections and understand its microscopic structure. To know the histology of a synovial joint and a symphysis joint (intervertebral disc) and the function of different tissues within the joints.

Reading: Human Anatomy, Marieb et al., 6th ed., pages 240‐260
Virtual Slides: Histology of Bone and Joints

The Skeleton

The body structure is formed by a series of bones, joints and cartilage, the bony part of the framework is called the skeleton.

Bone Structure

Haversian System

Individual bone forming cells (osteocytes) live in the spaces (lacunae) with the bone matrix surrounding a central blood vessel and nerve filled space (Haversian canal) that provides nutrition to these cells.

Vertebra and Intervertebral Disc

Ossification endochondral 1.jpg

Bone - Developing vertebra (bony collar) with newly formed bone matrix (red) surrounding mature bone forming cells (osteocytes) and with immature bone forming cells (osteoblasts) on the surface of the new bone.

Cartilage (blue) hyaline cartilage containing cartilage forming cells (chondrocytes) that are dying near bony collar (stacked large white spaces).

This cartilage formed the original template for where the bone will form and is gradually replaced, as these cells die, by bone formation (endochondral ossification).

Fibrocartilage forms a tough fibrous connective tissue (annulus fibrosus) around each Intervertebral disc that lies between 2 adjacent vertebra.

In the centre of each intervertebral disc is a jelly-like core (nucleus pulposus).
