This document contains histology slides and descriptions of various tissues including skeletal muscle, blood cells, cartilage, bone, nervous tissue, and epithelial tissues. Key tissues and structures highlighted include the sarcomere of skeletal muscle, elastic fibers in elastic cartilage, osteons in compact bone, the zonal organization of growth plate cartilage, and the layers of connective tissue. Descriptions and labels are provided to identify cell and tissue structures in each histology slide.
