Neuraxis
An imaginary line drawn through the center of the length of the central nervous system, from the bottom of the spinal cord to the front of the forebrain
-
Anterior
With respect to the central nervous system, located near or towards the head
-
Posterior
With respect to the central nervous system, located near or towards the tail
-
Rostral
"Towards the beak"; in a direction along the neuraxis away from the front of the face
-
Caudal
"Towards the tail"; in a direction along the neuraxis away from the front of the face
-
Dorsal
"Towards the back"; in a direction perpendicular to the neuraxis towards the top of the head or the back
-
Ventral
"Towards the belly"; in a direction perpendicular to the neuraxis towards the bottom of the skull or the front surface of the body
-
Lateral
Towards the side of the body, away from the middle
-
Medial
Towards the middle of the body, away from the side
-
Ipsilateral
Located on the same side of the body
-
Contralateral
Located on the opposite side of the body
-
Cross Section
With respect to the central nervous system, a slice taken at right angles to the neuraxis
-
Frontal Section
A slice through the brain parallel to the ground
-
Horizontal Section
A slice through the brain parallel to the ground
-
Sagittal Section
A slice through the brain parallel to the neuraxis and perpendicluar to the ground
-
Midsagittal Plane
The plane through the neuraxis perpendicular to the ground; divides the brain into two symmetrical halves
