Try a few questions
- Practice question 1
The eardrum (tympanic membrane) specifically functions to
- A.detect smell through specialized receptor cells
- B.regulate the amount of light entering the eye
- C.a function entirely unrelated to sound waves or vibration
- D.vibrate in response to sound waves, transmitting vibration further into the ear
Show the answer
D. vibrate in response to sound waves, transmitting vibration further into the ear
The eardrum's specific function is vibrating in response to sound waves and transmitting that vibration further into the ear.
- Practice question 2
The lens of the eye specifically functions to
- A.a function entirely unrelated to focusing light within the eye
- B.focus light onto the retina for clear vision
- C.regulate the amount of light entering the eye
- D.detect light directly, identical to the function of the retina
Show the answer
B. focus light onto the retina for clear vision
The lens's specific function is focusing light onto the retina for clear vision.
- Practice question 3
Reflex actions specifically serve a protective function, allowing the body to respond rapidly to
- A.no stimulus of any kind, despite reflexes being triggered by a stimulus
- B.potentially harmful stimuli
- C.only pleasant, non-threatening stimuli, rather than harmful ones
