The Senses

The video explains how sensory organs detect information from the environment and send it to the brain. It covers the five sensory organs: eyes, ears, nose, tongue, and skin, each with specialized receptors. These receptors are sensory neurons that convert external stimuli into electrical impulses sent to the brain. The brain processes these signals to create the sensory experiences that form our perception of the world.

What is the primary function of sensory organs?

• To detect information from our surroundings

• To create electrical impulses

• To process signals in the brain

• To bind chemicals in the air

Which sensory organ is responsible for balance?

• Nose

• Eyes

• Tongue

• Ears

What type of cells in the nose bind to chemicals in the air?

• Olfactory cells

• Sensory neurons

• Hair cells

• Photoreceptors

How do sensory neurons differ from other nerve cells?

• They are not connected to the brain

• They do not convert stimuli into impulses

• They pick up information from outside the body

• They are smaller in size

Where are the actual sensory experiences like sights and sounds created?

• In the sensory organs

• In the spinal cord

• In the brain

• In the nerve cells
