CH 11 Flashcards
These cells conduct impulses within the nervous system
neurons
master control and communication system of body
Nervous system
What are the three parts of the nervous system?
Sensory Input
Integration
Motor output
Nervous system that deals with the brain and spinal cord
Central Nervous System (CNS)
Nervous system associated with Cranial & Spinal Nerves that go from central nervous system to the periphery of the body
Peripheral Nervous System (PNS)
What are the two divisions of the Peripheral Nervous System (PNS) ?
Sensory (Afferent)
and
Motor (Efferent)
The motor division of the Peripheral nervous system is associated with what two nervous systems?
Autonomic Nervous System (ANS)
and
Somatic Nervous System
The autonomic nervous system has what two divisions?
sympathetic and parasympatheic divison
What central nervous system fibers run to the CNS?
Visceral and somatic senosry fibers
What central nervous system fibers run from the CNS?
Somatic nervous system motor fibers
Sympathetic and parasympathetic motor fibers
voluntary movment of muscles is a part of what nervous system?
Somatic Nervous System
Nervous system associated with involuntary control: such as heart and smooth muscles
Autonomic Nervous System
This part of the Autonomic Nervous System is stimulated during emergency situations.
sympathetic division
This part of the Autonomic Nervous System functions durning times of rest.
parasympathetic division
These aid neurons and do not carry nerve impulses
neuroglia
Star shaped neuroglia that stabilizes blood vesssels. Also, they respond to brain injury by filling in spaces.
astrocytes
What are the two neurogili of the CNS
astrocytes
and
microglia
These neuroglia are protective small white blood cells that phagocytize
microglia
ciliated cells found in the CNS that line ventricular (fluid) cavities of brain and spinal cord
ependymal cells
