Nervous System COLA
Wrong Answer | ||||
---|---|---|---|---|
What is the integration stage of the nervous system communication? | Interprets those changes in the brain drawing on our higher functions of intelligence, memory, learning, emotion. | |||
What does motor output do? | Responds by initiating action that might involve skeletal muscles or our internal physiological functions. | |||
What is the function of the Dendrites? | Receive (take in) signals from neurons, or other sensory cells (cells that give information about sight, smell, sound, touch and taste) | |||
What is the function of the Axon? | Transmit (send) signals to other neurons or cells in the body | |||
Does the Myelin Sheath increase or decrease the speed of electrical conduction? | Increase | Decrease | Neither, the conduction rate is equal along the axon | |
Hyperpolarization is referred to when the resting membrane potential is more.... | Negative | Positive | sensitized | desensitized |
Cell types that are components of the nervous system are.. | Glial cells and Neurons | Neurons and Myoglia | Myoglia and Glial cells | Neurons and Neurite |
Within a chemical synapse, the receptors.... | bind to very specific ligands | are only responsive to changes in voltage | bind to a variety of different ligands | are always degraded by enzymes in order disable them |
The Axon hillock.... | creates an action potential and transmits messages along axon | |||
What is an Action Potential? | when Neurones (nerve cells) communicate over long distances by generating and sending an electrical signal called a nerve impulse | |||
There is more or less sodium outside a cell | more | less | ||
There is more or less potassium outside a cell | less | more | ||
What phase is a neuron at if it is inactive | Resting Membrane Potential | Threshold | Refactory period | Action potential |
What does sensory output do? | Senses changes within body and in the external environment. | |||
What is the function of the axon terminals in a nerve cell? | They are specialized to release the neurotransmitters of the presynaptic cell. | |||
Describe the process of nervous system communication | Sensory, Integration, Motor | Integration, Sensory, Motor | Motor, Integration, Sensory | Motor, Sensory, Integration |
