Neurons
These make up the white matter of your brain
What are myelinated neurons?
Two categories of neurotransmitters.
What are inhibitory and excitatory neurotransmitters?
The structure in the brain that regulates homeostasis.
What is the hypothalamus?
Transmits visual information to the brain.
What is the optic nerve?
The organ of hearing.
What is the cochlea?
What are sodium ions.
The binding of this type of neurotransmitters on post-synaptic membrane causes K+ ions to flow out of the membrane.
What are inhibitory neurotransmitters?
Section of the cerebral cortex responsible for interpreting somatic sensory input.
What is the parietal lobe?
The area of the retina that lacks light sensitive cells thus producing no vision.
What is the blind spot?
What are the ossicles?
The process by which the electrical signal jumps from one node of Ranvier to another along a myelinated axon.
What is Saltatory conduction
What is acetylcholine?
Connects the right and left hemispheres and allows them to communicate.
What is corpus callosum?
The inability to see far objects
Connects the throat and the inner ear, allowing air pressure to equalize.
What is the eustachian tube?
The space between a presynaptic neuron and a postsynaptic neuron.
What is the synapse or synaptic cleft?
This area of the brain is responsible for conscious thought, intelligence, memory and personality, voluntary muscle movement and the Broca's area.
What is the frontal lobe?
A structure that increases low-light visibility in the eye, but is not found in humans.
The pathway of sound transmission to the brain.
Pinna>auditory canal>tympanum>ossicles>oval window>cochlea>auditory nerves
What are Schwann cells?
This neurotransmitter plays a crucial role in mood regulation and is often targeted by antidepressant medications.
What is serotonin?
The structure in the brain important for regulating vital functions such as breathing, heart rate, and blood pressure.
What is the medulla oblongata?
The section of the eye that provides blood vessels and nourishment.
What is the choroid layer?
Motion sickness is caused by this structure sending conflicting signals to the brain.
What are the semi-circular canal's?
