Study Notes
Understanding the Anatomical Terms and Planes of the Brain
- The brain can be studied in slices along different planes, including the axial, coronal, and sagittal planes.
- In an axial slice, you can see the left and right sides of the brain, but not the dorsal and ventral sides or the anterior and posterior sides.
- The spinal cord can be sliced along the transverse or coronal plane, which is the cross section.
- The cross section of the spinal cord is also known as the transverse plane.
- The midline of the body is the line that runs down the middle, and something close to the midline is referred to as medial.
- Lateral refers to something away from the midline and towards the sides.
- Motor functions in the nervous system often cross sides, which is referred to as contralateral.
- If something is on the same side, it is referred to as ipsilateral or same lateral.
- The brain can be divided into superior, middle, and inferior sections in the axial and coronal planes.
- The brain is usually studied in slices because it is a three-dimensional object that is difficult to visualize in three dimensions.
- The names of the slices can vary, with the transverse plane also being called the coronal plane.
- In an axial or horizontal slice, you can see the top of the ears, but not the dorsal to ventral or anterior to posterior sides of the brain.
