Nervous System and Senses

QuestionAnswer
Afferent Neurons Also called sensory neurons, they carry messages to the CNS.
Autonomic Nervous System A subdivision of the PNS that is involuntary.
Axon The structure of a neuron that carries a signal away from the cell body.
Brain Stem The portion of the brain that contains the medulla, pons and midbrain.
Central Nervous System The anatomy includes the brain and spinal cord, the physiology include integration.
Cerebellum The part of the brain that is responsible for movement and coordination.
Cerebrospinal Fluid The fluid that fills the ventricles of the brain and surrounds the brain and spinal cord. It's function is to help cushion and protect the CNS.
Dendrites The part of the neuron that senses stimuli and directs the impulse toward the cell body.
Depolarization The loss of the negative charge inside the cell. Occurs during a nerve impulse.
Efferent Neurons Also called motor neurons, they carry responses from the CNS to the effector organ.
Gray Matter Unmyelinated nervous tissue in the CNS.
Meninges The three layers of protective tissue around the brain and spinal cord.
Myelin A white, fatty substance that helps insulate axons and increase the effectiveness of the nerve impulse.
Nerve A bundle of neurons outside the CNS.
Neuron A nerve cell. A cell that is specialized to be irritable and conduct electrical impulses.
Nodes of Ranvier Gaps in the myelin that surrounds an axon.
Peripheral Nervous System The anatomy includes the nerves ound outside the brain and spinal cord. The physiology includes sensing stimuli and transmitting messages.
Plexus A complex network of nerves that controls a limb.
Polarized the states of an unstimulated neuron in which the inside of the cell is relatively negative in comparison to the outside of the cell; the resting state.
Receptor a peripheral nerve ending specialized for response to a certain type of stimulus, found on the ends of the dendrites.
Reflex Automatic responses to stimuli.
Repolarization Returning a cell to the polarized state.
Somatic Nervous System The voluntary subdivision of the PNS.
Synapse A region between neurons where they almost meet. Neurotransmitters are required to carry an impulse across the synapse.
White Matter Nervous tissue characterized by having myelin.
Blind spot The area of the retina where the optic nerve leaves the eyeball.
Lens Focuses the light that enters the eye.
Iris Acts as a diaphragm to control the amount of light that enters the eye.
Cornea The transparent anterior portion of the eye.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
