Planos Anatômicos e Eixos de Movimento: Introdução à Anatomia parte 2

Introduction to Anatomical Plans and Movement Axes

Overview of the Lesson

• The lesson introduces anatomical plans and movement axes, presented by Professor Natália Reinecke on her channel "Anatomia e Etc."

Anatomical Plans

• Anatomical plans are imaginary cuts that help describe the human body in three dimensions, essential for studying anatomy and interpreting medical imaging like CT scans.

• The main anatomical plans discussed include:

• Sagittal Plane: Divides the body into right and left halves.

• Frontal (Coronal) Plane: Divides the body into anterior (front) and posterior (back).

• Transverse Plane: Divides the body into superior (upper) and inferior (lower).

Detailed Description of Planes

• The sagittal plane is visualized as a vertical slice through the body, creating equal right and left halves.

• The frontal plane is also vertical but divides the body into front and back sections.

• The transverse plane is horizontal, separating the upper part of the body from the lower part.

Understanding Movement Axes

Concept of Movement Axes

• Movement axes are imaginary lines around which movements occur; they correlate with anatomical planes.

• An analogy is made comparing movement axes to door hinges, illustrating how movements pivot around these points.

Types of Movement Axes

1. Lateral-Lateral Axis:

• Also known as the transverse axis; it runs laterally across the body.

• Movements around this axis include flexion and extension.

2. Anterior-Posterior Axis:

• Runs from front to back; associated with abduction (moving away from midline) and adduction (moving towards midline).

3. Longitudinal Axis:

• Extends vertically from top to bottom; responsible for rotational movements.

Visualization of Movements

• For lateral-lateral axis, imagine a pin entering at a shoulder joint allowing flexion/extension but blocking other movements.

• For anterior-posterior axis, visualize a pin entering front-to-back at a shoulder joint enabling abduction/adduction while restricting flexion/extension.

• For longitudinal axis, think of rotation occurring along this vertical line through various joints.

Understanding Anatomical Plans and Axes

Anatomical Plans

• The anatomical plans are imaginary cuts that traverse the body, while axes are imaginary lines around which body movements occur.

• The median sagittal plane is a vertical plane dividing the body into equal right and left halves. Other sagittal planes run parallel to this median plane.

• There are also vertical cutting planes that separate the body into anterior (front) and posterior (back) sections.

Body Movement Axes

• The lateral-lateral axis runs horizontally across the body, perpendicular to the sagittal plane, allowing for flexion and extension movements.

• The antero-posterior axis extends from front to back through the frontal plane, facilitating abduction and adduction movements.

• The longitudinal axis runs vertically from top to bottom, perpendicular to the transverse plane, enabling rotational movements.
