Human Sensory System Functions

The video tutorial covers the five senses: sight, hearing, smell, taste, and touch. It explains the anatomy and function of each sense organ, including the eye, ear, nose, tongue, and skin. The tutorial also discusses how these senses are connected to the nervous system and how they send impulses to the brain. Additionally, it includes a demonstration of the Stroop effect and a practice quiz to reinforce learning.

What is the function of the cornea in the eye?

• To allow light to pass through

• To detect color

• To magnify light

• To create impulses

How does the iris respond to bright light?

• It stretches to make the pupil larger

• It contracts to make the pupil smaller

• It remains unchanged

• It changes color

What is the Stroop effect?

• A method to improve hearing

• A brain trick where the color of the text does not match the word

• A test to measure visual acuity

• A phenomenon where the color of the text matches the word

What role does the eardrum play in hearing?

• It amplifies sound

• It creates impulses

• It vibrates in response to sound

• It detects color

What happens when the cochlea vibrates?

• It magnifies sound

• It creates an impulse by bending hair cells

• It detects light

• It changes the color of sound

How are smell and taste related?

• They are not related

• They both detect light

• They both involve chemical receptors

• They use the same receptors

What is the function of chemo receptors in the nose?

• To detect light

• To detect pressure

• To detect sound

• To detect chemicals in the air

What type of receptors detect pressure on the skin?

• Photo receptors

• Chemo receptors

• Thermo receptors

• Mechano receptors

What do thermo receptors detect?

• Light

• Temperature

• Sound

• Pressure

Why do paper cuts hurt so much?

• They activate deep pressure sensors

• They activate pain sensors just beneath the skin surface

• They cause a large amount of blood loss

• They do not actually hurt
