reflexes, UMN,LMN Flashcards
1
Q
define rigidity
A
hypertonic state characterized by constant resistance
high tone
extremely hard to stretch
2
Q
hypotonia =
A
state of low muscle tone
3
Q
hypertonia =
A
abnormal increase in muscle tension
4
Q
dystonia =
A
abnormal muscle tone resulting in muscle spasm (hypertonia)
5
Q
5 components of reflexes
A
receptor afferent integrating efferent effector
6
Q
monosynaptic reflex=
A
transmission of info from a sensory neuron to the motor neuron across a single synapse
7
Q
polysynaptic reflex =
A
multiple roots and muscles receptor afferent interneuron efferent effector inhibitory neuron
8
Q
tone=
A
resistance of muscle to stretch
9
Q
spasticity=
A
increase in muscle tone with increased resistance to stretch
10
Q
rigidity
A
hypertonic state , constant resistance in ROM, high amount of TONE
11
Q
hypertonia
A
increased tone
12
Q
hypotonia
A
decreased or absent muscle tone
13
Q
dystonia
A
abnormal tone
