100
It is made up of the brain and spinal cord
What is the Central Nervous System?
100
It is a bundle of muscle fibers.
What is a fascicle?
100
It is the long cable like part of the nerve cell which transmits the impulse.
What is an axon?
100
Largest and most superior part of the brain; composed of two hemispheres.
What is the cerebrum?
100
Connective tissue around each neuron.
What is endomeurium?
200
It is made up of nerves outside the central nervous system.
What is the peripheral nervous system?
200
It is the connective tissue that surrounds each muscle fiber.
What is endomysium?
200
It is when a stimulus changes the permeability of the membrane and sodium ions rush into the nerve cell.
What is depolarization?
200
A line between anterior-posterior division between the two hemispheres of the cerebrum.
What is the longitudinal fissure?
200
Connective tissue around each group of neurons. (Around the perimeter)
What is perineurium?
300
It is a division of the PNS composed of nerves that carry information TO the CNS.
What is the sensory (afferent) division?
300
It is connective tissue that surrounds each bundle of muscle fibers (fascicle). (perimeter of the bundle)
What is perimysium?
300
It is the concept that a neuron will respond to a stimulus or it will not; there is no partial response.
What is the All-Or-None response?
300
They are elevated ridges on the surface of the cerebrum.
What are gyri?
300
Connective tissue aroun each nerve bundle. (Like our epidermis that covers our body)
What is epinueurium?
400
It is the division of the PNS composed of nerves that carry information FROM the CNS.
What is the motor (efferent) division?
400
It is the connective tissue that surrounds the entire muscle. (epidermis cells surrounds our body)
What is epimysium?
400
It is the restoration of the neg. charge on the inside of the membrane and it becomes impermeable to sodium and potassium ions diffuse out.
What is repolarization?
400
They are shallow grooves of the surface of the ceebrum.
What are sulci?
400
Complex network of spinal nerves that serve motor and sensory needs of the limbs.
What is a plexus? This image is of the lumbar plexus.
500
They are the names of the two divisions which work antagonistically with each other. One slows the nervous system down the other speeds the nervous system up. (hint: they were in the flow chart at station
What are the sympathetic and parasympathetic systems?
500
It is sensory receptors in muscles and tendons that detect stretching or tension to maintain balance and posture. (it is proper to maintain your posture)
What is proprioreceptors?
500
It is the name given to the transport of sodium and potassium with ATP use, back to their original state of the resting period.
What is the Soduium-Potassium Pump?
500
Area of the brain superior to the brain stem; which includes the thalamus, hypothalamus,and epithalamus.
What is the diencephalon?
500
It is an acute inflammation of teh meninges usually cause by viral or bacterial infections.
What is meningitis?
