Nerves
Chapter 11
Proprioception
ability to feel body's position in space
Golgi tendon organs
- tendon reflex
monitors force and muscle tension
~ most effective stimulation is by
electrical muscle stimulation
Ruffini's end organs
detect slow changes in joint position
Muscle spindle cells
- stretch reflex
monitor stretch and rate of change of muscle
Pacinian corpuscles
detect quick changes in joint pressure
Reflexes
Righting reflex
Head remaining steady
Crossed extensor reflex
Opposite side of body; stepping on a tack
Flexor withdrawal reflex
Automatic; hot stove
Reciprocal Inhibition
when one muscle contracts
its antagonist relaxes
Stretching
Variables
Duration
need at least 10 seconds
Speed
Force
Types
Post-isometric relaxation
Reciprocal Inhibition
CRAC combined
RI + PIR
Patterns
Movement pattern
creating in CNS
Law of facilitation
creating deeper neural pathways
Resting tone
state of muscle at rest
