Unit 5 - Nervous and Sensory Systems

In this unit we study the nervous system and the important functions it performs. Of course incorporated within the nervous system is the sensory system. We will examine the anatomy and physiology of two organs of the sensory system-- the eye and the ear. We will then focus our attention on the basic unit of the nervous system, the neuron (nerve cell), and study how a neuron carries a nerve impulse.

Instruction in this unit will consist of a worksheet, set of power point presentations, and several short video lessons.

Specific Assignments

Assignment 1: Use your textbook to label the parts of the the brain, the eye, and the ear in the Nervous System worksheet. (Click here to see worksheet)

Assignment 3: The goal of this assignment is to learn and understand how neurons transmit nerve impulses. Afterwards, be prepared to discuss with your instructor how nerves transmit impulses.

Watch the video below entitled "Action Potential."



Assignment 4: Neural Synapse. Study the video below entitled "Synaptic Transmission" to learn how nerve impulses transfer from one neuron to the next. Study the accompanying diagram in the worksheet.



Assignment 5: Structure and Function of the Sensory system - power point. Take notes. Make sure you have completed the appropriate parts of the worksheet. Click here to access the power point.

Quiz: Nervous and Sensory System: Quiz will test your knowledge of the functions of the nervous system, major parts of the brain and their associated functions, vocabulary from the worksheet, and structures of the eye and ear. Also, know the basic structure of a neuron and be able to explain how a nerve impulse is transmitted.
