Understanding Human Sensory Organs

The video tutorial covers the anatomy and functions of the eye and ear, explaining how these organs process visual and auditory stimuli. It begins with an introduction to the topic of stimuli and responses, followed by a detailed examination of the eye's structure and the mechanism of vision. The tutorial then shifts focus to the ear, detailing its anatomy and the process of hearing. The session concludes with a summary and a preview of the next topic, which will cover the nose, tongue, and skin.

Which of the following is NOT a human sensory organ?

• Ear

• Nose

• Heart

• Eye

What is the primary function of the retina in the eye?

• To protect the eye

• To change the shape of the lens

• To focus light

• To detect light and convert it into neural signals

Which part of the eye is responsible for controlling the amount of light entering?

• Optic nerve

• Iris

• Retina

• Cornea

How does the brain interpret the images formed on the retina?

• As blurred images

• As upright images

• As inverted images

• As black and white images

What is the function of the pinna in the ear?

• To transmit sound to the brain

• To balance pressure

• To collect sound waves

• To amplify sound

Which part of the ear contains the ossicles?

• Inner ear

• Outer ear

• Cochlea

• Middle ear

What role does the cochlea play in hearing?

• It converts sound waves into neural signals

How are sound waves transmitted to the brain?

• Through the optic nerve

• Through the auditory nerve

• Through the olfactory nerve

• Through the spinal cord

Which part of the ear helps in maintaining balance?

• Semicircular canals

• Eardrum

• Auditory canal

• Cochlea

What is the function of the eustachian tube in the ear?

• To collect sound waves

• To balance air pressure

• To amplify sound

• To transmit sound to the brain
