100
A specialized cell transmitting nerve impulses
What is a neuron?
100
Most important body system responsible for glands and hormones
What is the endocrine system
100
the dips and ridges of the brain
What is the gyri and sulci of the brain?
100
Helps refract light onto the retina, also helps keep debris out of the eye
What is the cornea
100
A disorder in which the nerve cell activity in the brain is disturbed causing seizures
What is epilepsy?
200
The message is received by the dendrites, then goes down through the axon to the axon terminals through the synaptic cleft and is passed to the next neuron for the process to start over
What is the path an action potential takes down the neuron?
This structure is responsible for depth perception
What is the retina
200
A disorder of the central nervous system that affects movement, often including tremors
What is Parkinson's disease?
300
What are the two different ways in which the neurons communicate?
What is electrical and chemical communication?
300
Midbrain, pons, medulla oblongata
What is the 3 parts of the brain stem?
300
Tiny structures on the retina that are responsible for sensing color and movement
What is rods and cones
300
Name of disease in which both myopia and hyperopia are present; common among elderly
What is presbyopia
400
Step 1: Arrival of stimulus and activation of receptor
Step 2: Activation of a sensory neuron
Step 3: Information processing in CNS
Step 4: Activation of a motor neuron
Step 5: Response by effector
What is a reflex arc?
400
regulates emotion, memory, and directly connects lower and higher brain functions: takes part in controlling autonomic/involuntary functions
What is the function of the limbic system?
400
Path light takes through the eye (7 structures)
What is cornea, aqueous humor, iris-pupil, lens, vitreous humor, and retina
500
A short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory
What is an action potential?
500
These two systems work together to make sure important information gets to your brain to be processed and interpreted and to make sure that the correct response is generated
What is the Central Nervous System and the Peripheral Nervous System?
500
Region of greatest visual acuity due to more cones in this area of the eye, used when visual detail is of primary importance
