Sensory Perception and the Central Nervous System

Flashcards reviewing the five senses and the central nervous system's interpretation of sensory information, focusing on the auditory system.

What is the primary function of our five senses?

Gather information.

What is the role of the central nervous system (brain & spinal cord)?

Interprets the information gathered by our senses.

What are the three tiny bones, collectively known as ossicles, in the middle ear?

Hammer, anvil, and stirrup.

What is the function of the ossicles (hammer, anvil, and stirrup)?

To transfer vibration to the cochlea.

What is the function of the auditory nerve?

Carries impulses to the brain.

What is the function of the ear drum?

Transfers vibration.

What is the function of the cochlea?

Changes vibration into impulses and sends it to the auditory nerve.

What is the correct order of structures involved in transmitting sound from the ear canal to the cochlea?

Ear canal → Ear drum → Ossicles (hammer, anvil, and stirrup) → Stirrup → Cochlea.
