Transcript of Vestibular & Kinesthetic Sense

Vestibular Sense Organs
Proprioception
awareness of body position
Kinesthetic Sense Organs
Kinesthetic Sense
The system for sensing the position and movement of individual body parts
Also helps detect weight and is responsible for our body awareness
our sense of having our own bodies, including our sense of having and locating our body parts.
develops as we grow older

Vestibular & Kinesthetic Sense

eyes
,
muscles

joints
,
inner ear
help us maintain
balance
Eyes
sensory info from cones sent to the brain to help one identify how they are oriented around an object
cones help us see color and fine detail
rods help us see in low light conditions
Muscles & Joints
help us remain stable
they signal body position and mvt
Inner Ear
Three semicircular canals in inner ear
Send messages to brain about speed and direction of body rotation
vestibular sacs: detect gravitation and mvt sensations
mill. of tiny crystal bend hair cells when moved, impulses of sense of position are sent to brain
fluid in the semicircular canals pushes on the hair cells that transduces the mechanical movement into electric signals (transduction)

Vestibular Sense
ability to maintain balance & good posture
which way our head is tilting
whether we are moving or not
can get motion sickness from excessive vestibular sense stimulation
Gather info from receptions that respond to stretching muscles, joints, skin, and tendons.
travel to brain via spinal cord
cortical regions + cerebellum receive and send info to vestibular system which prompts proprioception
Child Development
Gross
motor skill: walking, crawling, etc.
Fine
motor skill: holding objects
Visual spatial
motor skill: follow moving objects
Vestibular sense can help with child development
Vestibular
Activity Time
Muscles, joints, and tendons are involved in your kinesthetic senses
The sensory neurons bring the sensory info up to the brain, allowing transduction to occur
