Answer 46

Eustachian tube

Question 47

What is the potential risk of having the cerebellum damaged? Please explain the potential symptoms as discussed in the lecture and lab.

Answer 47

If it was damaged you can risk the function of skeletal movements. Your movements would no longer be precise and smooth. Your posture and equilabrium would be off balance.

Question 48

Explain color blindness.

Answer 48

color blidness happens when you lack of one cone type. cones are the reason that we can see detailed color vision and lack of them disrupts color therefore being color blind.

Question 49

Place the ear ossicles in sequence from the tympanic membrane to the oval window. Spelling counts.

Answer 49

Sound waves strike the tympanic membrane and cause vibration. The vibration travels from the ossicles to the oval window. 3 bones conduct vibration in the ear. Malleus, Incus and stapes.
