Q

Can you tell what this is and with this stain can you differentiate b/w other similar tissues?

A

this is elastic cartilage, but looks almost identical in H&E - Verhoeff’s stain is needed to differentiate

What cell type is at the yellow circle?

osteocytes

What cell type is at the yellow circle?

osteocytes

What cell type is at the yellow circle?

osteoclasts

What cell type is at the yellow circle?

osteoclasts

What process is happening here and where does it occur?

intramembranous ossification - flat bones

What structure is in the yellow circle?

spicules

What process is happening here and where does it occur

endochondral ossification - long bones

What zone of the epiphyseal plate is seen here?

RESTING ZONE (the zone where hyaline cartilage is untouched)

What zone of the epiphyseal plate is seen here?

ZONE OF PROLIFERATION (chondrocytes begin to proliferate rapidly in long stacks)

What zone of the epiphyseal plate is seen here?

ZONE OF HYPERTROPHY (chondrocytes begin growing rapidly - calcification has not yet occurred)

What zone of the epiphyseal plate is seen here?

ZONE OF CALCIFICATION (osteoblasts and osteocytes begin to invade the cartilage and calcification begins)

What zone of the epiphyseal plate is seen here?

ZONE OF RESORPTION (bone mods occurs here)

What structure is located at the arrow?

Haversian canal

What structure is located inside the black circles?

Haverisan canal

What structure is located inside the yellow circle?

What do the blue lines indicate?

lamellae (concentric rings)

What do the yellow lines indicate?

lamellae

What is the white structure at the end of the yellow arrow?

lacunae

What is the white structure at the end of the yellow arrow?

lacunae

What are the line structures at the tip of the blue arrows?
