Lecture 3

Lecture 3: Nervous Tissue and Action Potential

QuestionAnswer
Function of the Nervous System maintain homeostasis of the organism in a constantly changing environment
Central Nervous System (CNS) brain and spinal cord, integration and encoding of sensory and motor information
Peripheral Nervous System (PNS) nerves and ganglia, interface between environment and CNS
Ganglia clusters of nerve cells
Afferent Division brings sensory information to the CNS
Efferent Division carries motor commands from the CNS to target tissue and organs
Neurons functional unit of the nervous system
Synapse specialized site for communication between neurons
Association Neurons important for signal integration, called interneurons, located within the CNS
Sensory Neurons afferent neurons, transmit information from a sensory receptor to the CNS
Motor Neurons efferent neurons, transmit information from the CNS to an effector organ (muscle)
Dendrites thin processes that extend from the cytoplasm
Axon carries information encoded by the dendrites and soma away from the neuron toward other neurons or organs
axolemma membrane surrounding the axon, extension of the cell membrane
axoplasm cytoplasm of the axon
Axon Hillock origin of the axon where the action potential originates
Electrochemical Gradient a difference in ion concentration and charge across a membrane
Leakage Channels channel proteins which are always open
Gated Channels channels proteins which change conformations to allow ions to pass through, can be open, closed, or inactive
Electromotive Force emf= Vm-Eion

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.
