Human Tissues--Quiz Yourself! Visualize Structures Discuss Functions of Tissue Chapter 40 p

Epithelial Identify what function of each of these tissue types makes them critical in the following example organs:

Connective tissue: What is a main feature of all connective tissue? With blood as an exception, what material is central to connective tissue?

Pancreas Tissue Islets of Langerhans-2 Connective Tissue-3 Blood Vessel-4

Thyroid Tissue Connective Tissue Hormone secreting cells Storage of Hormone

Blood Red Blood Cells Platelets Monocytes Neutrophils/Basophils

Adipose Tissue Brown vs. White –Brown-generates heat; infants/animals that hibernate –White “ typical fat ”

Muscle Tissue Intercalated disks Multinucleated Striations Cardiac Muscle Tissue Skeletal Muscle Tissue Smooth Muscle Tissue

Neuron Cell Body Nucleolus Cellular processes (axons) Glial cells: cells that maintain neural tissue…do not communicate!

Lung Tissue Bronchi –Ciliated columnar Alveoli –Simple squamous

Small Intestine Connective Tissue Goblet cells (pseuodostratified columnar)

Compact Bone (Ground) “ Osteon ” Haversian Canal Location of Blood vessels/nerves Osteocytes Canaliculi

Cartilage Chondrocytes Matrix Hyaline Fibrous Elastin

One More…Kidney What type of tissue? Can you identify –Cells –Sinuses

Can YOU find and interpret tissue samples? Lab Goals: 1.Glands: Pancreas, thyroid—Recognize characteristics of secreting cells 2.Blood: Identify 3 different types of cells in a blood smear 3.Adipose tissue: Identify characteristics that distinguish this tissue 4.Muscle: Identify characteristics associated with smooth, skeletal, cardiac. 5.Neuron: Distinguish 3 main parts of a neuron 6.Lung tissue: Identify the epithelial tissue types associate with lung tissue 7.Small intestine: Identify the epithelial tissue types associated with small intestine 8.Bone/cartilage: Be able to distinguish cell structures and difference between bones and cartilage
