1 Histology II Return of the Tissue Review • There are 4 basic types: – Epithelium, Connective, Muscle, Nervous • We already covered the 1 st and 3 rd – Recall there are 7 Epis and 3 Mus • We will deal with the others today

2 Connective Tissue • Connective tissue is quite diverse belying its broad range of function • There are 4 types of connective tissue – Fibrous Connective Tissue (largest class) – Cartilage – Bone – Blood Fibrous Connective Tissue • Unlike the epithelial and muscle tissues where the cells are closely apposed, connective tissue is rich with external proteins. • You saw this in the lab when looking at “real” sections of organs last time • We are going to first describe the components of FCT.

3 Cells of FCT •F ib rob l a s t – Large flat cells – They produce fibers ( blast = produce) FITC, Rhodamine, and Dapi Cells of FCT – 2 • Macrophage

4 Cells of FCT – 3 • Adipocytes (Fat cells) – Easily identified by large lipid-filled vacuole – Can be found in small clusters in some FCTs – When dominant: Adipose tissue Cells of FCT - 4 • Plasma Cell – An “activated” leukocyte that makes antibodies – Rare, but in intestines and inflamed tissue
