The Vestibular System (Balance)
- 2 Components:
- 3 Semicircular Canals
- Posterior
- Anterior
- Lateral (or "horizontal"
- 2 Otolith Organs
- Utricle
- Saccule
- Similarities: filled with fluid & hair cells
Anmerkungen:
- - Each are filled with fluid and a small patch of sensory hair cells
- Movements result in fluid flow which displaces hair cells and leads to sensory responses
- Principle Planes & Axes
- 3 linear Axes: X, Y, Z
- Z Axes: along the spine and out the top of the head
- Y Axes: Through our ears out the other side
- X Axes: From back of the head, through our noes in front of us
- Rotate around these axes (but stay within the plane of the other two)
- Frontal (Roll)
- Like a cartwheel around the X axes
- Median (Pitch)
- Like nodding your head or forwards roll around the Y axes
- Transverse (Yaw)
- Z Axes - Pirowet spinning around on the spot
- Any movements we make are combinations of these 6 ways of moving
Anmerkungen:
- Along the:
X, Y & Z Axes
Frontal (roll), Medium (pitch), Transverse (yaw) planes
