What does plane mean in anatomy?
A flat surface formed by making a cut, imaginary or real, through the body or a part of it. Planes are used as points of reference by which positions of parts of the body are indicated. In the human subject, all planes are based on the body being in an upright anatomical position.
What is plane in anatomy and physiology?
A plane in anatomy & physiology is defined as an imaginary flat surface that passes through the body parts.
What are the 4 planes in anatomy?
The anatomical planes are four imaginary flat surfaces or planes that pass through the body in the anatomical position. They are the median plane, sagittal planes, coronal (frontal) planes and horizontal (transverse) planes (figure 2). Anatomical descriptions are also based on these planes.
What are the planes in biology?
An anatomical plane refers to a hypothetical plane used in describing the location of bodily structures or movement directions. The three planes that are commonly used in human and animal anatomy are sagittal plane, coronal plane, and transverse plane.
What is axis and plane?
A plane is an imaginary flat surface running through the body. An axis is an imaginary line at right angles to the plane, about which the body rotates or spins.
What is the ventral plane?
Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).
What are the planes of the human body?
Anatomical planes in a human:
- median or sagittal plane.
- a parasagittal plane.
- frontal or coronal plane.
- transverse or axial plane.
What are the three planes of the body?
The three planes of motion are the sagittal, frontal and transverse planes.
- Sagittal Plane: Cuts the body into left and right halves. Forward and backward movements.
- Frontal Plane: Cuts the body into front and back halves. Side-to-side movements.
- Transverse Plane: Cuts the body into top and bottom halves.
What is a transverse plane in anatomy?
Axial Plane (Transverse Plane) – A horizontal plane; divides the body or any of its parts into upper and lower parts. Median plane – Sagittal plane through the midline of the body; divides the body or any of its parts into right and left halves.
What is frontal plane in anatomy?
Coronal Plane (Frontal Plane) – A vertical plane running from side to side; divides the body or any of its parts into anterior and posterior portions. Sagittal Plane (Lateral Plane) – A vertical plane running from front to back; divides the body or any of its parts into right and left sides.
What are the three major anatomical planes?
In human and animal anatomy , three principal planes are used: The sagittal plane or median plane (longitudinal, anteroposterior ) is a plane parallel to the sagittal suture. The coronal plane or frontal plane (vertical) divides the body into dorsal and ventral (back and front, or posterior and anterior) portions.
What are the different anatomical planes?
Anatomical Planes in a Human: There are three basic planes in zoological anatomy: sagittal, coronal, and transverse. A human in the anatomical position, can be described using a coordinate system with the Z-axis going from front to back, the X-axis going from left to right, and the Y-axis going from up to down.
What are the anatomical planes of the human body?
An anatomical plane is a hypothetical plane used to transect the human body, in order to describe the location of structures or the direction of movements. In human and animal anatomy, three principal planes are used: The sagittal plane or median plane (longitudinal, anteroposterior ) is a plane parallel to the sagittal suture.
What are the planes of the body?
Axial Plane ( Transverse Plane) – A horizontal plane; divides the body or any of its parts into upper and lower parts. Median plane – Sagittal plane through the midline of the body; divides the body or any of its parts into right and left halves. The cavities, or spaces, of the body contain the internal organs, or viscera.
