Anterior 1. the side toward front of organism as it approaches you 2. used for organisms with bilateral symmetry and/or are cephalized (having a head region) B. Posterior 1. side farthest away from you as organism approaches II. Histology – the study of tissues (group of similar cells doing a specific function) A. The 4 Basic Types of Tissue in Animals 1. Epithelial Tissue(thin layers of cells lining outer surface of body or inner surfaces of organs) a. 3 main functions: protection, secretion, and/or absorption b. 3 basic shapes: squamous (flat), cuboidal , and columnar c. arrangement: single layer (simple) of cells or multiple layers (stratified) of cells 2. Connective Tissue a. includes cartilage, bone, blood, and tendons b. consists of living cells embedded in an extracellular matrix 3. Muscle Tissue a. 3 types: skeletal , smooth , and cardiac 1. Skeletal: muscles we have control over
