|
Each kind of sound triggers a different cell in the inner ear
|
|
|
Sound waves enter the brain through openings on the skull
|
|
|
Receptors pick up the information about sound waves and send it to the brain.
|
|
|
The ear sends signals out into the environment and interpret what comes back
|
Detailed explanation-1: -Animals sense the environment with body parts called sensory organs, such as eyes, ears, and noses. Sensory organs are vital for animals to find food, locate mates, and avoid danger. We humans have five senses-sight, hearing, smell, taste, and touch; that’s not too shabby a list, if we say so ourselves.
Detailed explanation-2: -As the sound travels between ears through the animal’s body, each eardrum is activated by different sounds at its outer and inner surface that help the animal determine the source of the sound. For example, the ear facing more toward the sound source vibrates with a larger amplitude than the eardrum facing away.
Detailed explanation-3: -Transduction is the process by which sensory stimuli are translated into signals the brain can interpret. Transduction occurs at sensory receptors, specialized cells in each sense organ. Sensory receptors send messages to the thalamus, which sends projections to cortical areas for perceptual processing.
Detailed explanation-4: -Sensory receptors enable animals to perceive their external world, and functional properties of receptors evolve to detect the specific cues relevant for an organism’s survival. Changes in sensory receptor function or tuning can directly impact an organism’s behavior.
