Nervous System Flashcards
The prostate is innervated by what spinal cord level(s)? (sympathetics)
T12-L2
________ summation is when one neuron receives multiple impulses from a single neuron, and the build up of these action potentials allows for the threshold to be reached.
Temporal
The bladder is innervated by what spinal cord level(s)? (sympathetics)
T11-L2
In a sympathetic response, salivary α amylase ________.
Increases
The ________ tract is responsible for rapid delivery of noxious impulse, sharp, well localized, warn of progressive injury.
Neospinothalamic
The upper extremities are innervated by what spinal cord level(s)? (sympathetics)
T2-T6
The lower extremities are innervated by what spinal cord level(s)? (sympathetics)
T11-L2
Vasoconstriction, iris dilation, intestinal sphincter contraction, pilomotor contraction, and bladder sphincter contraction all occur when ________ receptors are triggered.
Alpha
________ occurs when both alpha and beta receptors are triggered.
Intestinal relaxation
Nociceptors are free nerve endings that are not ________.
Encapsulated
The kidneys are innervated by what spinal cord level(s)? (sympathetics)
T10-T11
The appendix is innervated by what spinal cord level(s)? (sympathetics)
T12
The adrenal medulla is innervated by what spinal cord level(s)? (sympathetics)
T10
________ sensory neurons are large and myelinated and are responsible for sharp and localized pain.
Aδ-fast
The lower ureters are innervated by what spinal cord level(s)? (sympathetics)
T12-L1
What are two examples where the parasympathetic nervous system does NOT perform an opposite function of the sympathetic nervous system?
1)
Sympathetic: constricts most blood vessels
Parasympathetic: little effect on blood vessels
2)
Sympathetic: increases basal metabolic rate
Parasympathetic: no effect on basal metabolic rate
The ________ tract is responsible for achey, poorly localized, limbic interaction = long term motivational and emotional dimensions of pain.
Paleospinothalamic
The upper ureters are innervated by what spinal cord level(s)? (sympathetics)
T10-T11
Vasodilation, cardioacceleration, uterine relaxation, bronchodilation, bladder wall relaxation, and glycogenolysis all occur when ________ receptors are triggered.
Beta
________ summation is when one neuron receives input from multiple neurons in order for the threshold to be reached.
Spatial
________ sensory neurons are small and unmyelinated and responsible for dull and achy pain.
C-slow
Visceral pain is mainly transmitted by ________.
C fibers
The uterus and cervix are innervated by what spinal cord level(s)? (sympathetics)
T10-L2
