Question Answer
Monitoring changes and gathering information (Afferent Division)Sensory input (PNS)
Processing and interpreting dataIntegration (CNS)
Effects a response via muscles, glands, etc (Efferent division)Motor output (PNS)
The nervous system has how many overlapping functionsThree
The two parts of the central nervous system are the Brain and Spinal cord
What nerves are PNS nerves that carry information to and from the brain?Cranial
Nerves that carry information to the CNS areAfferent
Nerves that carry information to the CNS areEfferent
PNS stands for Peripheral Nervous System
CNS stands forCentral Nervous System
Voluntary nervous system, carries messages to skeletal musclesSomatic Nervous System
Carries messages to smooth muscle and cardiac muscle, glands, adipose tissueAutonomic Nervous System
Neuron: Part with NucleusCell Body
Neuron: Transmits impulses towards cell body; branched receiving endsDendrites
Neuron: Transmits impulses away from cell bodyAxon
Is the whitish fatty material that insulates axons, poreventing the neuron from short-circuitingMyelin
Are collections of cell bodies in the PNSGanglia
Several dendrites and one axon; lots in the CNSMultipolar
Single, short process that divides immediatelyUnipolar
One dendrite and one axon; found in special sense organsBipolar
Meissner's and Pacinian corpuscles are examples ofGeneral sensory receptors
Connect afferent and efferent neuronsInterneurons
Are support cells for neurons in the CNSNeuroglia
Produce myelin sheaths in the CNSOligodendrocytes
Are specialized to receive and transmit impulsesNeuron
Ciliated; produce and circulate cerebrospinal fluidEpendymal cells
Produce myelin sheaths in the PNSSchwann Cells
Form blood-brain barrier; brace neuronsAstrocytes
Phagocytes in the CNS; clear debrisMicroglia
Integration center for a reflex arc is located in the CNS
Nerves and muscles are able to receive and respond to stimuli, therefore, they are Irritable
touch, pressure, pain, hot/cold, stretch position from all over bodySomatic Sensory Receptors
unconscious monitoring of internal organsVisceral Sensory Receptors
Smell, taste, vision, hearing, balanceSpecial Sensory Receptors
Reflex Arc (in order) receptor, sensory neuron, information processing, motor neuron, effector
Involuntary (Sympathetic - fight or flight, Parasympathetic - rest and digest)Autonomic Nervous System
Motor division of PNSSomatic Nervous System and Autonomic Nervous System
Junction of nerve signalsSynapse
