Clinically Oriented Anatomy (Moore)
-somatic nervous system
-autonomic nervous system correct answers functionally, the nervous system is divided
into:
-provides sensory and motor innervation to all parts of the body, except the viscera in
the body cavities, smooth muscle and glands
-voluntary control correct answers Somatic nervous system
-visceral nervous system
-responsible for control of the bodily functions not consciously directed
-ex: breathing, heartbeat, digestive processes correct answers autonomic nervous
system
-sympathetic
-parasympathetic correct answers the ANS can be subdivided into two divisions:
"fight or flight" correct answers sympathetic nervous system
"feed or breed"
"resting & digesting" correct answers parasympathetic nervous system
structural and functional units of the nervous system specialized in rapid communication
correct answers neurons
-cell body
-dendrite (extensions)
-axon (carry impulses to and away from the cell body) correct answers neuron is
composed of:
-around some axons
-increase the velocity of impulse conduction correct answers myelin sheath
-mulitpolar motor neuron
-pseudounipolar sensory neuron correct answers two types of neurons:
-have two or more dendrites and single axon that may have one or more branches
-most common type
-all of the motor neurons that control skeletal muscle and those comprising the ANS
correct answers multipolar motor neurons
-short, single process extending from the cell body
, -all sensory neurons of the PNS are these, with cell bodies located in sensory ganglia
correct answers pseudounipolar sensory neuron
non-neural, non-excitable cells that form a major component of nervous tissue,
supporting, insulating, and nourishing the neurons
-more abundant than neurons correct answers neuroglia (glial cells or glia)
-communication between two neurons
-usually use a chemical neurotransmitter correct answers synapse
a collection of nerve cell bodies in the CNS correct answers nucleus (CNS)
-nerve cell bodies lie within and constitute this
-more superficial (brain)
-horns
-anterior vs. posterior correct answers gray matter
-the interconnecting fiber tract systems form this
-deep (brain)
-axons correct answers white matter
group of cells in the PNS correct answers ganglia
perikaryon correct answers cell body also called?
-along with the CSF, these membranous layers surround and protect the CNS correct
answers meninges
-pia mater (innermost, thin)
-arachnoid mater (middle)
-dura mater (deep, tough) correct answers the three meninges that surround the CNS:
-glial cell
-"supporting cell" of the PNS
-form the myelin sheath around axons with internodal regions in the PNS correct
answers Schwann cell
-glial cell
-"supporting cell" of the CNS
-forms myelin sheaths around axons in the CNS correct answers oligodendrocytes
consists of the cell membranes of Schwann cells that immediately surround the axon,
separating it from other axons correct answers neurolemma
endoneurium
-delicate
