NEURONS
This part of the neuron receives incoming information.
What is a dendrite?
A junction where one neuron communicates with another.
What is a synapse?
This structure connects the brain to the spinal cord.
What is the brain stem?
The eardrum is also known by this anatomical name.
What is the tympanic membrane?
The conversion of sound energy into neural signals.
What is transduction?
The distance between two musical notes.
What is a musical interval?
This part carries action potentials away from the cell body.
What is the axon?
These potentials occur mainly in dendrites and cell bodies.
What are graded potentials?
The medulla oblongata, pons, and this structure make up the brain stem.
What is the midbrain?
Malleus, incus, and stapes are collectively known as these.
What are the auditory ossicles?
These cells are the primary sensory receptors of hearing.
What are inner hair cells?
Two notes played at the same time form this type of interval.
What is a harmonic interval?
Sensory, motor, and this type make up the three major neuron types.
What are interneurons?
These all-or-none signals travel down the axon.
What are action potentials?
The thalamus, hypothalamus, epithalamus, and subthalamus are parts of this region.
What is the diencephalon?
This spiral-shaped structure converts sound vibrations into neural signals.
What is the cochlea?
These cells can amplify motion within the cochlea.
What are outer hair cells?
Two notes played one after another form this type of interval.
What is a melodic interval?
This division of the nervous system consists of the brain and spinal cord.
What is the Central Nervous System (CNS)?
The three major gate types discussed were leak, ligand-gated, and this.
What are electrically gated (voltage-gated) channels?
This lobe is located at the back of the brain.
What is the occipital lobe?
This structure sits on the basilar membrane and contains the hair cells.
What is the Organ of Corti?
Low-frequency sound localization relies heavily on differences in this.
What is timing (phase) between the ears?
These curves show how perceived loudness changes with frequency.
What are equal loudness curves?
The nervous system's five major functions include sensation, integration, motor output, homeostasis, and this.
What is mental activity?
This pump moves sodium out and potassium into the neuron.
What is the sodium-potassium pump?
Frontal, parietal, temporal, and occipital are all parts of this major structure.
What is the cerebrum?
Vibrations along this membrane help separate sounds by frequency.
What is the basilar membrane?
High-frequency localization relies heavily on sound shadowing and differences in this.
What is intensity (loudness)?
These brief beginnings of sounds help the brain identify instruments and speech.
What are transients?
A signal from your eyes travels through this division before reaching the CNS.
What is the Peripheral Nervous System (PNS)?
This type of synapse uses neurotransmitters to carry signals across a gap.
What is a chemical (ligand) synapse?
Deep brain structures tend to handle this type of processing rather than conscious thought.
What are basic survival and automatic functions?
This membrane contacts the stereocilia of hair cells.
What is the tectorial membrane?
This principle allows groups of neurons to collectively represent frequencies higher than a single neuron can fire.
What is the volley principle?
The emotional meaning of music depends on culture, context, and this.
What is personal experience?
