Acinus – Cells arranged into a circular secretory unit

Adipocyte – Large cell (up to 200 microns) with only a thin film of cytoplasm due to the presence of a large fat droplet.

Adipose tissue – A group of adipocytes.

Bone – Specialized connective tissue with a mineralized (hydroxyapatite) matrix.

Collagen – A triple helix protein which allows for great tensile strength.

Goblet cell – special mucus secreting columnar epithelial cell located in the respiratory tract and intestine.

Lacunae – A cavity or depression especially in the bone
