Document Summary

~know the tissues and special functions as well as special characteristics (review lab notes on tissues)~ Typical epithelial tissue: avascular (cells nourished via diffusion). Structure polarity: (has apical layer (top)) and the basement layer (bottom) Simple squamous- location inner lining of the blood vessel (tunica intima). Fxn: controls permeability of vessel, reduce friction, absorption and secretion. Simple cuboidal- cube shaped cells: location: kidney, pancreas, secreting endocrine glands. Transitional epithelium- location: only found in the urinary bladder. Psuedostratified ciliated columnar(pscc)- location : trachea and bronchi fxn: protect linings due to. Fibroblast: produce collagen for strength and framework organs. Areolar= lose connective tissue- framework for all organs. Dense regular connective tissue- location: muscle tendons (connects muscle to bone) fxn: strength and support. Dense irregular connective tissue- location: dermis of the skin. Fxn: provides flexibility, strength and support, connects skin to muscle. Elastic connective tissue- location: tunica media of the blood vessels. Fxn: elasticity to vasculature to combat pressure changes.

Build a dichotomous key to all the tissues you have seen in the lab. For this, you can use any of their morphological characteristics (under the microscope) but not their physiological functions.

Tissues seen in this lab:

1) Epithelia: simple squamous, simple cuboidal, simple columnar, pseudostratified columnar, stratified squamous, stratified cuboidal and columnar, transitional, and specialized epithelia (goblet cells).

2) Connective Tissue: Adipose, Areolar, Cartilage, hyaline cartilage, fibrocartilage, elastic cartilage, bone and blood.

3) Muscle: Smooth muscles, Cardiac muscles, skeletal muscle

4) Nervous tissues: Neurons, central nervous system (CNS), satellite cells, schwann cells, ependymal cell
