Classification of Tissues: Connective Tissue Connective Tissue: a tissue that supports, transports, binds, and protects structures in the body Turn to page 62 of the lab book and pages 15-17 of the lab packet

Types of Connective Tissue

I will use BOTH microscopes AND histograms to test you on epithelial tissues. Make sure you look at the microscopes in lab and the histograms in this presentation.

Make sure you know all the pieces of information listed in your lab packets! Also know the locations of ALL tissues!

Loose Connective Tissue: Areolar Tissue Find: matrix/ground substance, collagen fibers, elastic fibers, nuclei of cells

Loose Connective Tissue - Areolar note the collagen fiber at the pointer and the black elastic fibers. Also note the nuclei of cells.

Areolar Tissue

Loose Connective Tissue: Adipose Tissue Page 62 Loose Connective Tissue: Adipose Tissue Adipocyte! Lipid Droplet

Loose Connective Tissue: Adipose Tissue Find: adipocyte, lipid droplet, nucleus of an adipocyte

Loose Connective Tissue – Adipose Note: Adipocytes, Lipid Droplets, Nuclei of Adipocytes

There is a Histology Practice Test on my webpage! Use it to study and review!

Lab Exam 1 30 stations with 2-3 ques. Per station Format: 30 stations with 2-3 ques. Per station 80 questions total – all fill-in with no word lists or multiple choice (spelling counts!) 1 min. 35 seconds per station with 5 min. at end to go back   Covers: Language of Anatomy – Figure with body regions, directional terms, figure with body cavities, serous membranes, 4 abdominal quadrants, 9 abdominopelvic regions Organ systems – Torso model with organs (know name and which organ system they belong to) Skull anatomy – don’t forget to study the sinus figure from your lab book Fetal Skull – fetal skull anatomy using fetal skull models Epithelial tissue – BOTH microscopes and histograms on the exam! Know name and 1 specific location of each. Connective tissue – BOTH microscopes and histograms! Know name and 1 specific location of each.
