Cranial Nerves
Cranial Nerve I
Responsible for fight or flight.
What is sympathetic nervous system?
The resting potential of a neuron (mV).
What is -70mV?
The four lobes of the brain.
What are frontal, parietal, temporal, and occipital lobes?
Progressive loss of brain function with major impacts on memory, thinking, and behavior.
What is Alzheimer's Disease?
Cranial Nerve X
What is Vagus Nerve?
The autonomic nervous system is broken down into these two systems.
What are sympathetic and parasympathetic nervous system?
What are Nodes of Ranvier?
Number of Vertebrae and Number of Spinal Nerves. (2 different numbers)
What are 33 vertebrae and 31 spinal nerves?
Loss of neurons in the parts of the brain that correlate to memory formation as well as conscious perception.
Cranial Nerve VII
What is Facial Nerve?
Nerves that transmit impulses from sensory receptors to the CNS
What are Afferent (sensory) nerves?
Stage in which influx of Na+ ions raises potential to +40mV
What is Depolarization?
Classification (type) of all the neurons in the dorsal root ganglion.
What is pseudounipolar?
Autoimmune condition in which the body's immune system targets and eliminates. the myelin sheath of axons.
Cranial Nerve IX
What is Glossopharyngeal nerve?
Part of the neuron responsible for conducting neural impulses
What is an axon?
Opening of these channels results in repolarization stage.
What are Voltage gated K+ channels?
Encasing of groups of fascicles as well as blood vessels.
What is Epineurium?
Collection of blood that lies below the dura mater, no definitive shape. Result from damage to venous structures in the brain.
What is Subdural Hematoma?
Cranial Nerve VIII
What is Vestibucochlear nerve?
Responsible for the myelination of neurons in the Peripheral Nervous System.
What are Schwann Cells?
Stage that results in potential of -80 mV to -90 mV.
What is Hyperpolarization?
Extends from T1 to L3 and contains the cell bodies of sympathetic nerve fibers.
What is Lateral Horn?
Result of spinal cord injury at C3-C4 level.
What is Quadriplegia?
