PLANES & AXES- BASIC BIOMECHANICS

PLANES & AXES 

# Human movement takes motion in a plane and about an axis

# To explain movement, the body can be viewed as having a series of imaginary slices/glass panes running  through it.

# The anatomical position is the point of reference for all movements:

* The human body standing erect

* Face facing forward

* Arms by the sides

* Palms facing forward

* Legs straight

* Feet flat on the floor and turn out very slightly.

PLANES

The anatomical position is further standardized by dividing the body into three anatomical planes

A plane is an imaginary flat surface passing through the body which divides the structure.

The surface at which the movement takes place is called plane.

1. SAGITTAL PLANE

2. FRONTAL PLANE

3. TRANSVERSE PLANE

AXES

The human body is also divided into anatomical axes.

* Axis of rotation is an imaginary line (point of rotation) that passes through a joint or the body to describe the movement

All movements rotate around one of the axes.

The point at which movement takes place is called axis.

1. Horizontal/ Frontal Axis

2. Sagittal Axis

3. Longitudinal/ Vertical Axis
