AXES AND PLANES

Question 1

• lines that movements occur around which movements occur.

Answer 1

Axes

Question 2

• imaginary surfaces that divide the body for reference and analysis.

Answer 2

Planes

Question 3

• a hypothetical line extending from the anterior to the posterior end of the body.

Answer 3

Longitudinal axis

Question 4

• a hypothetical line, at right angles to both longitudinal axes from the dorsal to the ventral surface.

Answer 4

Transverse axis

Question 5

• a vertical longitudinal plane passing from head to tail through the centre of the body from the dorsal to the ventral surfaces.

Answer 5

Median or midsagittal plane

Question 6

• the plane which divides the structure into right and left halves. When the plane does not coincide with the median plane, it is called parasagittal plane.

Answer 6

Sagittal plane

Question 7

• any horizontal section through the body; that is, all planes at right angles to the median plane and parallel to the dorsal and ventral surfaces.

Answer 7

Horizontal or frontal plane

Question 8

• any section cut vertically across the body at right angles to the sagittal and horizontal planes; relating to a plane separating the anterior and posterior ends.

Answer 8

Transverse or cross plane
