Motor in the Brain
100
Also known as the ear drum
What is the tympanic membrane
100
Transmits auditory information from the cochlea to the brain
What is the cochlear nerve
100
The system by which info about different frequencies is coded by different locations on the basilar membrane
What is place coding
100
A neuron whose axon forms synapses with extrafusal muscle fibers of a skeletal muscle; activation contracts the muscle fibers
What is an alpha motor neuron
100
The primary motor cortex shows this type of organization
What is somatotopic organization
200
Bones of the middle ear
What are ossicles
200
Receives auditory information from the cochlea
What is the cochlear nucleus in the medulla
200
This device uses place coding to restore hearing in people with deafness caused by damaged hair cells
What is cochlear implants
200
Forms synapses with intrafusal muscle fibers
What is a gamma motor neuron
200
This brain area plays a critical role in behavioral sequences
What is the supplementary motor area
300
The sensory organ on the basilar membrane that contains the auditory hair cells
What is the organ of corti
300
Neurons in the cochlear nucleus send axons to where?
What is the superior olivary nucleus
300
This end of the basilar membrane responds best to highest frequencies
What is the basal end
300
The synapse between the terminal button of an efferent neuron and the membrane of a muscle fiber
What is the neuromuscular junction
300
This system of axons controls movements of the distal limbs, such as hands and fingers.
What is the lateral corticospinal tract
400
A membrane located above the basilar membrane; serves as a shelf against which cilia move
What is the tectorial membrane
400
Axons of neurons in superior olivary nucleus pass through the lateral lemniscus first and then synapse in this midbrain structure
What is the inferior colliculus
400
Lower frequencies are detected by means of
What is rate coding
400
The receptor organ at the junction of the tendon and muscle that is sensitive to stretch
What is the Golgi tendon organ
400
These neurons respond when the individual makes a particular movement or sees another individual making that movement
What are mirror neurons
500
The snail-like structure of the inner ear that contains the auditory transducing mechanisms
What is the cochlea
500
Auditory information passes through many synapses along the way but eventually ends up here
What is the auditory cortex of the temporal lobe
500
The difference in arrival times of sound waves at each of the ear drums
What are phase differences
500
The postsynaptic membrane of a neuromuscular junction
What is motor endplate
500
Mirror neurons are found in these 2 areas of the brain
What is the ventral premotor cortex & inferior parietal lobule
