Description

Week 5 Nervous System- Sensation Learning Objectives:

Understand the types of sensory neurons and their responses to different stimuli.
Describe the response of a sensory receptor to chemical stimuli at the cellular level

Introduction:

The body is continually bombarded by stimuli from the changing environment. To respond successfully, the body must be able to interpret these stimuli. Sensory receptors enable us to make sense of these signals by converting them into nerve impulses which are then interpreted by the brain. Let’s see if we can learn enough about pain stimuli and how to block them in time to help our injured climber get back to safety!

Assignments:

Part 1 Labster “Sensory Transduction: Learn why you feel pain when you get hit by a rock”

Have the lab report available to record data as you work through the lab. The theory section of the lab is a useful resource.

Part 2 Complete the lab report.

Nervous System Lab Report: Sensation

Record the information you learned about sensory receptors. (1 point each for total of 5 points)
a. Why is capsaicin used in the experiment? (1.5 points) b. What is capsaicin? (1.5 points)
Which of the sensory receptors plays a key role in homeostasis? (2 point)
Which of the receptors would be found in joints, ligaments, tendons and muscle? (1 point)
Where in the body would you find photoreceptors? (1 point)
Multiple choice: (1 point) What does a longer latency to withdrawal time reflect?
While it may sound like a wonderful thing to never have to feel pain, discuss why not being able to feel pain would be detrimental to one’s health. (2 points)
