#4 Thick skin, H&E

Below the epithelium (epidermis) is the dermis, which is dense connective tissue with many fibers and relatively few cells. Underneath the dermis is the hypodermis with a large amount of adipose tissue.

#12 Blood Smear, Wright’s Stain

The vast majority of cells are erythrocytes. Locate individual white blood cells and examine them at higher magnification.

#5 Trachea, H&E

Find the ring of cartilage in the wall of the trachea which appears as somewhat shiny bluish tissue with many cells trapped in it.

#9 Dried Bone, Shaft of Tibia, Human, no stain

This section has been prepared by grinding down a piece of dried bone until it is thin enough to transmit light. The small dark regions are the sites where there were bone cells in life. There are also regions where blood vessels penetrate the bone.

#11 Rib, Cross Section, H&E

This section was prepared by decalcifying bone so that it could be cut and then staining it. There are some portions of surrounding muscle and connective tissue outside the bone and some marrow on the inside.

#116 Tongue Skeletal Muscle, H&E

The outer surface of the tongue contains projections (the papillae). The skeletal muscle runs in various directions in deep regions. Use high enough magnification to see the striations.

#39 Colon, H&E
