coronal plane

Examples of coronal plane in the following topics:

• Body Planes and Sections

  • There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.
  • The coronal plane (frontal or Y-X plane) divides the body into dorsal and ventral (back and front) portions.
  • The coronal plane, the sagittal plane, and the parasaggital planes are examples of longitudinal planes.
  • For example, during human embryonic development the coronal plane is horizontal, but becomes vertical as the embryo develops into a fetus. 
  • There are three basic planes in zoological anatomy: sagittal, coronal, and transverse.

• Sutures

  • In newborns and infants, the areas of connective tissue between the bones are much wider, especially in those areas on the top and sides of the skull that will become the sagittal, coronal, squamous, and lambdoid sutures.
  • Late in life, the sagittal, coronal, and lambdoid sutures of the skull will begin to ossify and fuse, causing the suture line to gradually disappear.

• Sutures

• Autopsy

  • These examinations are performed under a legal authority (Medical Examiner or Coroner or Procurator Fiscal) and do not require the consent of relatives of the deceased.
  • Within the United Kingdom, clinical autopsies can be carried out only with the consent of the family of the deceased person as opposed to a medico-legal autopsy instructed by a Coroner (England & Wales) or Procurator Fiscal (Scotland) to which the family cannot object.

• Overview of the Male and Female Reproductive Systems

  • One of the most significant features of the human penis isn't so much the glans per se, but rather the coronal ridge it forms underneath.
  • This results in the coronal ridge that runs around the circumference of the shaft.

• Cranial Bones

  • To the front the parietal bones form the coronal suture with the frontal bone, and to the rear the lambdoid suture with the occipital bone.
  • The frontal bone borders two other neurocranial bones, the parietal bones through the coronal sutures and the sphenoid bone through the sphenofrontal suture.

• Types of Synovial Joints

  • (plane joint at clavicle)
  • The types of the synovial joints are based on the shapes and can be classified as plane, hinge, pivot, condyloid, saddle, and ball and socket.
  • The articulating surfaces of the plane joint are usually flat to allow slipping and gliding properties.
  • These joints act as a door hinge does, allowing flexion and extension in just one plane.

• Basal Ganglia

  • Two schematic drawings of coronal sections of human brain labelling the basal ganglia.

• Anatomical Position

  • In humans, the standard anatomical position of the skull is called the Frankfurt plane.
  • In this position, the orbitales (eye sockets), lower margins of the orbits, and the poria (ear canal upper margins) all lie in the same horizontal plane.

• Chambers of the Heart
