What is an axis of the body?

A coronal or frontal plane is perpendicular to the ground and divides the body into dorsal (posterior or back) and ventral (anterior or front) portions. A transverse plane, also known as an axial plane or cross-section, divides the body into cranial (head) and caudal (tail) portions.

In this way, what are the 3 axis of rotation?

An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail.

What are planes and axes?

The frontal plane also lies vertically and divides the body into anterior and posterior parts. An axis is a straight line around which an object rotates. Movement at a joint takes place in a plane about an axis. There are three axes of rotation.

What axis does flexion occur?

An exception is extension of the thumb, which takes place in a frontal plane about a sagittal axis. Flexion occurs when the angle between two adjacent segments in the body decreases as the ventral surfaces of the segments approximate each other and occurs in a sagittal plane about a frontal axis.
