Topic 35-4: The Senses
(Dragonfly Textbook Pages 906-909)
1)
What are sensory receptors?
2)
How do we sense light (vision)?
a. Corneab. Irisc. Pupild. Lense. Retinaf. Rodsg. Conesh. Foveai. Optical nerve-
3)
How do we hear and maintain balance?
a. Hearing
– Sound vibrations enter ear causing eardrum to vibrate
– Hammer and Anvil vibrate, and Stirrup transmits
vibration to oval window
– Pressure waves travel through fluid-filled cochlea
– Hair cells in cochlea move, producing
nerve impulses that are sent to brain
b.Balance
-Semicircular Canals monitor the position of your body
(esp. head) in relation to gravity to help your CNS
maintain equilibrium
4) How do we smell and taste?
5) Touch and Related Senses
