kinesthetic sense Flashcards
what are your kinesthetic sense
vestibular system and proprioceptive system
what is your vestibular system
tells us where our body is in space, canal in inner ear
what is your proprioceptive system
tells us where our body parts are relative to our body
what system does your vestibular sense integrate with
your visual sense
what are the parts of proprioception
-muscle spindle
-tendon receptors
-joint capsule receptor
what the muscle spindle
sense stretch in muscle and very sensitive to rate of stretch
what is your stretch reflex
stretched muscle causes reflexive contraction of muscle being stretched
what is tendon receptors
senses muscle tension
what is inverse myotatic reflex
tension on tendon causes reflexive relaxation of muscle being contracted
what is joint capsule receptors
sense compression in joint capsule
how can it be neurally enhanced
-increasing stimulation frequency
-recruiting more motor units
-reducing inhibitory firing
-synchronizing the firing of motor units
how is muscle force accomplished
by increasing size and amount o contractile proteins
muscle contraction needs neural drive volitional contraction from?
efferent impulses
sensory components of movement from receptor to CNS
afferent impulses
what are the sensory component of movement
starts in receptor via specific spinal tract cross over in medulla to sensory cortex
