Parts of a Neuron
Where is the nucleus located?
In the cell body/soma.
What is the occipital lobe?
Causes difficulty in reading and writing text, pronunciation, poor spellling
Dyslexia
Where is visual information processed?
Occipital lobe/primary visual cortex
What is the snail-shell shaped part of the ear with fluids that transmit vibrations to the basilar membrane?
Cochlea
What is the purpose of the axon?
The axon acts as the bridge that transports signals from one end of the neuron to the other
Controls vital functions, like breathing and blood pressure
What is the brain stem?
Easily startled, often stressed, difficulty in sleeping/staying awake, trouble focusing, caused by witnessing/experiencing a stressful event
Post Traumatic Stress Disorder (PTSD)
What nerve relays visual information from the retina to the optic chiasm and forward to the occipital lobe?
The optic nerve
What converts the vibrations/pressure into electrical signals?
What is the difference between the dendrites and the axon terminal?
The dendrites takes in electrical signals whereas the axon terminal sends out electrical signals
Coordinates movement and speech, also responsible for critical thinking and planning
What is the frontal lobe?
Feeling of need to have things perfect, often wants everything to be clean, obsessive behavior
Obsessive Compulsive Disorder
What is the difference between rods and cones?
Rods are used for lower light levels, and cones are used to see in brighter areas
What is the eardrum also known as?
typanic membrane
What are the nodes of ranvier and the myelin sheath
The nodes of ranvier are the spaces in between the myelin sheath, and the myelin sheath acts as an insulator for the axon
What is the difference between the temporal lobe and parietal lobe?
Deals with memory and emotion, interprets auditory information whereas the other regulates sensory signals, including touch, pain, taste respectively
Results in sudden seizures, fainting, breathing difficulties, can be triggered by flashing lights
Epilepsy
What are the two types of visual processing streams?
dorsal (where) and ventral (what)
Part of the brain that helps with understanding and producing speech
wernickes area
What are schwann cells/oligodendrocytes?
A type of glial cell (support cell) which maintains the myelin sheath
What is the amygdala?
Regulates emotion and memory
Also known as trisomy 21, results in flatter face, smaller ears, short neck, caused by a lack of the 21st chromosome
Down Syndrome
Where do the ventral stream go?
the temporal lobe
Where does the auditory nerve lead?
The Thalamus
