- Threshold Stimulus
- Neuronal Cell Body
- Bipolar Neuron
- a collection of nerve cell bodies found outside the CNS
- b The membrane has become more negative than resting potential. Until the channels close.
- c The amt of stimulus needed to create an action potential. NA+ rushes into the cell increasing the number of positive ions inside the cell and changing the membrane polarity
- d site of the nucleus and most important metabolic area
- e one axon and one dendrite
5 Multiple choice questions
- The cumulation of action potential of all neurons in a nerve
- one single process leading away from the soma; afferent neurons are unipolar
- How does the membrane maintain the difference in electrical charge established by diffusion of ions?
- What is the relationship between myelination and size and conduction velocity?
- carry signals toward the CNS from the body periphery; sensory neurons
5 True/False questions
Multipolar Neuron → one axon and multiple dendrites; efferent neurons and interneurons are multipolar
Interneuron → surrounds each nerve fiber
deep pressure, cold temperature → The amt of stimulus needed to create an action potential. NA+ rushes into the cell increasing the number of positive ions inside the cell and changing the membrane polarity
Neurofibril → specialized supporting cells in the CNS
Repolarization → K+ moves out of the cell causing the membrane potential to move in a negative direction.
