Seat of intelligence, abstract reasoning is in the Frontal lobe
Ciliated CNS neurologia that play an active role in moving the cerebrospinal fluid are called ependymal cells
The sheath of Schwann is also called the neurolemma
An excitatory neurotransmitter secredted by motor neurons innervating skeletal muscle is acetylcholine
The period after an initial stimulus when a neuron is not sensitive to another stimujlus is the refractory period
The part of a meuron that conducts impulses away from its cell body is called axon
the role of acetylcholinesterase is to destroy ACh a bried perion after its release by the axonal endings
collections of nerve cell bodies outside the central nervous sysytem are called ganglia
a neuron that has as its primary function the job of connecting other neurons is association neuron (inter neuron)
Which of these ions is actively transported through the cell membrane to establish a restion potential Na
an action potential is essential for impulse propagation
Meuroglia that control the chemical environment around neurons by buffering potassium and recapturing meurotransmitters are astrocytes
An inhibitory postsynaptic potential (IPSP) is associated with hyperpolarization
The brain stem consists of the midbrain medulla and pons

White matter (myelinated fibers) is found in what locations copus callosum, corticospinal tracts, outer surface of the spinal cord
Loss of ability to perform skilled motor activities such as piana playing with no paralysis or weakness is specific muscles might suggest damage to the premotor cortex
