Central Nervous System
What do the spinal cord's dorsal/ventral/lateral horns direct?
What type of signal do the spinal nerve's ventral/dorsal roots carry?
What is the X structure of the spinal cord/what structure of the spinal cord is X?
- Conus medullaris
- Filum terminal
- Cervical enlargement
- Lumbosacral enlargement
How are the meninges arranged around the spinal cord?
Peripheral Nervous System
What direction would afferent/efferent neurons of the autonomic nervous system bring signals?
Which of the following functions would be triggered by the sympathetic/parasympathetic response?
What is dual innervation?
What is the preganglionic/postganglionic neuron?'
Where is the soma of the preganglionic/postganglionic neuron located?
How are the sympathetic/parasympathetic divisions different in terms of:
- Length of preganglionic neurons
- Length of postganglionic neurons
- Capacity for mass activation
- Types of ganglia
- Locations of ganglia
- Neurotransmitter used at the ganglionic synapse
- Neurotransmitter used at the effector
What are the three types of sympathetic pathways?
Where does the synapse occur in X sympathetic pathway?
What type of receptor is found at the ganglion/effector for the sympathetic/parasympathetic/somatic division?
Which of the following is/isn't one of the types of adrenergic receptors?
Is X adrenergic receptor excitatory or inhibitory?/Which of the following is an excitatory/inhibitory adrenergic receptor?
Does X adrenergic receptor have a higher/lower/equal affinity for epinephrine vs norepinephrine?
How do synapses occur at the autonomic neuroeffector junction?
How does the somatic division differ from the autonomic in terms of
- Where in the spinal cord do somatic motor signals originate
- Neurotransmitter is used for somatic motor signals
- Receptor used at neuroeffector junctions for the somatic division
- Ganglia use
- Number of neurons used in a pathway
