Terminology in anatomy and kinesiology Flashcards
What is anatomy?
Structure of the body
Focus on structure
E.g., study on the bicep brachii
What is functional anatomy?
Body components necessary to achieve a goal
Focus on function
E.g., analysis of bicep curl
What is kinesiology?
Scientific study of human movement
Anatomical, physiology, psychological, biomechanical
What is biomechanics?
Application of mechanics to biological systems
More specific than kinesiology
Name the 2 types of skeleton
Axial
Appendicular
What makes up the axial skeleton?
Head, neck and trunk
What makes up the appendicular skeleton?
Upper and lower extremities
Hips
Arms and legs
Name the 4 reference systems
Axes
Origin
Relative
Absolute
What is the ‘axes’ reference system?
Imaginary lines that intersect at right angles
What is the ‘origin’ reference system?
Point of intersection of axis
What is the ‘relative’ reference system?
Segment movement described relative to adjacent segment
What is the ‘absolute’ reference system?
Axes intersect in the centre of a joint
Name 2 reference positions
Anatomical
Fundamental
Explain the anatomical position
Standard reference point with palms facing the front
Explain the fundamental position
Arms more relaxed with palms facing inwards
Name the 10 relative positions
- anterior
- posterior
- medial
- lateral
- proximal
- distal
- superior
- inferior
- ipsilateral
- contralateral
Explain anterior
Movement towards the front
Explain posterioir
Movement towards the back
Explain medial
Towards midline of the body
Explain lateral
Away from midline of the body
Explain proximal
Towards point of attachment
Explain distal
Away from point of attachment
Explain superior
Towards the top of the head
Explain inferior
Towards the bottom of the feet
Explain ipsilateral
On the same side
Explain contralateral
On opposite sides
What is a plane?
A flat, two dimensional surface which a movement takes place
What are cardinal planes?
Planes positioned at right angles and intersecting the centre of mass
Explain axis of rotation
Point about which movement occurs
Perpendicular to plane of motion
Name the 3 types of planes
Sagittal
Coronal/frontal
Transverse/horizontal
What is the sagittal plane?
Left and right halves
Mediolateral axis
Flexion and extension
Forward and backward motion
What is the coronal/frontal plane?
