Class Summary - Today we started out class looking at different pictures of different tissues. Students were supposed to identify the tissues and then explain why they choose that specific tissue. See attached pictures for examples. Today we talked about nervous tissue. We discussed that nervous tissue is found in the brain and the spinal cord. We talked about the three parts (and their purposes) of a neuron; dendrite, axon and body. We talked about nervous conducting impulses that are actually sensed in the brain. Neuroganglia take up most of the brain and they outnumber neurons 9-1. We also talked about Schwann cells which enclose all nerve cells that are located outside of the brain.
Homework - The test is scheduled for Friday. Students should be prepared to label a connective tissue diagram (collagen, adipose, blood, elastic and fibroblasts) Identify pictures of tissues and explain WHY they chose it Label the three pictures of junctions (gap, tight and adhesion) Label the parts of a neuron (no word bank) Use the one word 'c' words that describe tissue functions Answer several short answer questions about various tissues Label a graphic organizer of nervous tissue Match the neroglia to its function (microglia, ogliodendrocytes, astrocytes and ependymal cells) Match the cartilage to its function and location (hyaline, elastic, fibrocartilage)
Objectives - Students will know the location and function of neurons. Students will identify neurons from a picture. Students will identify characteristics and appearance of different junctions.
