Transcript of Final Notes of Chapter 4

Vestibular Organ
Located in the inner section of your ear, which sense information about orientation and movement.

Composed of:
semicircular canals

the linked saccule and utricle

Question: Which organ provides the most sensitive messages to the brain?

Look in your book in chapter 4! Also, be able to explain why!
Write down answer #1
Semicircular Canals
3 circular tubes that lie at right angles to one another providing information on orientation of the body- left and right, up and down, and front and back

At the base, there are gelatin-like structures (receptors) called the cupula which sticks out into the enlargement of the canal.

Final Notes of Chapter 4
Orientation, Skin Senses, Pain, Stroop Effect
Skin Receptors
We usually do not think of skin as a sense organ, but it picks up a ton of sensory information.

They can detect 3 things: what are these three things? Which in particular detects primarily temperature and pain? Write down answer #3
Why do we get nausea?
As the head is titled, the fluid flows through the canal in a opposite direction which bends the cupula and causes its receptors to tell the brain it is "tilting" but sometimes it can backfire.

In your book, find and explain why this could backfire? Write down the answer #2
Nocioceptors- receptors for stimuli that are experienced as painful

Neural messages are transmitted down two separate paths

This is why we experience "first and second pain" (video)

Describe the two types of pain Ricky Bobby Felt.

Write answer down #4

Also answer, why is it important for us to experience pain according to researchers? Write down answer #5
Stroop Effect test
go to this website and take the test! Record five times for each test and write them down for answer #6
In psychology, the Stroop effect is a demonstration of interference in the reaction time of a task. Created by John Ridley Stroop
