1. Classify Epithelial tissue into types based on structure, location, histology, and function Naming: Simple , Stratified ; Squamous , Cuboidal , & Columnar Simple : Consists of 1 cell layer Stratified : 2 or more layers Squamous : Flattened & scale like Cuboidal : Boxlike, approximately as tall as they are wide Columnar : Tall & column shaped Note: Stratified epithelia are named according to the shape of the cells in the apical layer

2. Classify Connective Tissue into types based on structure, location, histology, and function 1. Connective Tissue Proper : All mature connective tissues (minus blood, cartilage and bone) are Connective Tissue Proper a. Loose Connective Tissue : i. Areolar : 1. Description : Gel-like matrix with all three fiber types; cells: fibroblasts, macrophages, mast cells, and some white blood cells 2. Function: Supports & binds tissues (fibers), holds body fluids (ground fluid), defends against infection (white blood cells & macrophages), stores nutrients as fat in adipocytes (fat cells) 3. Location : Widely distributed under epithelia of body, e.g., forms lamina propria of mucous membranes; packages organs; surrounds capillaries

2. Classify Connective Tissue into types based on structure, location, histology, and function 1. Connective Tissue Proper : All mature connective tissues (minus blood, cartilage and bone) are Connective Tissue Proper a. Loose Connective Tissue : i. Adipose : (subtypes white & brown), 1. Description: Matrix as in areolar, but very sparse; richly vascularized, closely packed adipocytes, or fat cells, have nucleus pushed to the side by large fat droplet. 2. Function : Provides reserve food fuel; insulates against heat loss; supports and protects organs. 3. Location: Under skin in subcutaneous tissue; around kidneys and eyeballs; within abdomen; in breasts

2. Classify Connective Tissue into types based on structure, location, histology, and function 1. Connective Tissue Proper : All mature connective tissues (minus blood, cartilage and bone) are Connective Tissue Proper a. Loose Connective Tissue : i. Reticula : 1. Description : Loose network of reticular fibers in a gel-like ground substance; reticular cells lie on the network.Only has reticular fibers.

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
