acquired reflexes
|
Rapid and automatic, but they are learned rather than reestablished. Enhanced by repetition
|
|
arachnoid mater
|
the middle menix that encloses cerebrospinal fluid and protects the central nervous system
|
|
convergent neural pool
|
Several neurons synapse on a single postsynaptic neuron
|
|
cranial reflexes
|
Important interconnections and processing events occur in nuclei of the brain
|
|
crossed extensor reflex
|
involves a contralateral reflex arc because an additional motor response occurs on the side opposite the stimulus
|
|
dermatone
|
a sensory region monitored by the dorsal rami of a single spinal segment
|
|
divergence
|
In neural tissue, the spread of information from one neuron to many neurons; an organizational pattern common along sensory pathways of the central nervous system
|
|
dura mater
|
The outermost component of the cranial and spinal meninges
|
|
endoneurium
|
a delicate network of connective tissue fibers that surrounds individual nerve fibers
|
|
epineurium
|
A dense layer of collagen fibers that surrounds a peripheral nerve
|
|
innate reflexes
|
Result from connections that form between neurons during development and are genetically or developmentally programmed
|
|
meninges
|
Three membranes that surround the surfaces of the central nervous system; the dura mater, the pia mater, and arachnoid
|
|
monosynaptic reflexes
|
A reflex in which the sensory afferent neuron synapses directly on the motor efferent neurons
|
|
muscle spindle
|
Sensory receptors involved in the stretch reflex
|
|
parallel processing
|
Occurs when several neurons or neuronal pools process the same information simultaneously
|
|
perineurium
|
A connective tissue partition that separates adjacent bundles of nerve fibers in a peripheral nerve
|
|
pia mater
|
the innermost layer of the meninges bound to the underlying neural tissue
|
|
polysynaptic reflexes
|
A reflex in which interneurons are interposed between the sensory fiber and the motor neuron(s)
|
|
reciprocal inhibition
|
Coordinates muscular contractions and reduces resistance to movement
|
|
reverberation
|
A positive feedback along a chain of neurons such that they remain active one stimulated
|
|
serial processing
|
Information is relayed in a stepwise fashion, from one neuron to another or from one neural to the next
|
|
somatic reflexes
|
Provide a mechanism for the involuntary control of the skeletal muscles. Immediate response that can be later supplemented by voluntary motor commands
|
|
spinal reflexes
|
The important interconnections and processing events occur in nuclei of the spinal cord
|
|
visceral reflexes
|
autonomic reflexes control or adjust the activities of smooth muscle, cardiac muscle, and adipose tissue
|
|
withdrawal reflexes
|
Move affected parts of the body away from a stimulus
