B3-Structure of the Nervous System Flashcards
Anterior
With respect to the central nervous system, located near or toward the head
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
Posterior
With respect to the central nervous system, located near of toward the tail
Rostral
“Toward the beak”; with respect to the central nervous system,in a direction along the neuraxis toward the front of the face
Caudal
“Toward the tail”; with respect to the central nervous system and direction along neuraxis away from the front of the face
Dorsal
“Toward the back”; with respect to the central nervous system and a direction perpendicular to the neuraxis toward the top of the head or the back
Ventral
“Toward the belly”; with respect to the central nervous system in a direction perpendicular to the neuraxis toward the bottom of the skull or the front surface of the body
Lateral
For the side of the body, away from the middle
Medial
Toward 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 slice taken at right angles to the neuraxis
Frontal section
Sliced through the brain parallel to the forehead
Horizontal section
A slice through the brain parallel to the ground
Sagittal section
Slice it a brain parallel to the neuraxis and perpendicular to the ground
