Exam Review 3 Flashcards
Two functional divisions of the autonomic nervous system include
Sympathetic and Parasympathetic
Name a neurogila found in the central nervous system
Astrocyte
Mircogilia
ependymal
Oiliogodendrocytes
What neurogila are responsible for producing myelin sheaths
Oligodendrocytes
Schwann Cells
Clusters of neuron bodies found in the CNS are referred to as
Nuclei
The perphel buldge of schwann cell cytoplasm as it secretes myelin sheaths
Neurilemma
Bundles of processed in the PNS are called
Nerves
The potential difference across membrane of a resting cell is reffered to as
Resting membrane potential
Incoming short distance signals are known as
Graded potentials
Continuous conduction is faster than salatory conduction
false
Action potentials are an all or none phenomenon meaning the depolarization of the membrane must reach a certain _____ in order to generate an action potential
Threshold Stimulus
Information leaving the CNS is known as
Stomatic and Visceral efferent
The membrane maintains its resting state by
the Na-K pump
A synapse that cause depolarization of the post synaptic membrane is known as
ESPS
Which of the following are vital for regeneration of damaged peripheral fibers
Astrocytes
These Neurons are responsible for shuttling information through the CNS
Interneurons
The third ventricle is located near the
Diencephalon
The area of the brain that controls visual motor information is the
Frontal Eye view
The gustatory cortex is located in the
Insula lobe
Nerves that only carry information to the CNS are classified as
afferent
What is the structure that pyramidal motor tracts use to travel from the cerebrum to the brain stem
Cerebral Peduncles
Transversely orientated folds in the cerebrum are called
Folia
Extensions of the pia mater that anchor the spinal cord to the dura mater are
Denticulate Ligaments
The area of the spinal cord that recieves stomatic information
Dorsal Grey horn
Ascending pathway contain ___ neurons and deliever ____ information
three
sensory
A skin prick and a cold compress are all classified as what information
Stomatic afferent
Cells that migrate towards the CNS neurons that have been damaged are called
Mircogilla
Clusters of cell bodies found within the PNS are
Ganglia
Action potentials that travel among the axon toward the cell body of the neuron have
distal direction
_____ fibers are the slowest nerve fibers and have the smallest diameter
Group C
The resting membrane potential of a neuron is -70mV this is because there are more positive or neg ions on the inside?
More positive on the outside then on the inside
In the resting state the neuron cell membrane is highly more permeable to which ion?
K+
An increase in cell membrane potential is known as
Hyperpolarization
The time from the opening of the Na+ channels untill the resting of these channels
Absolute refractory period
