3.2 Flashcards
Caudal
“Toward the tail”; with respect to
the central nervous system, in a direction
along the neuraxis away from the front of
the face
Dorsal
“Toward the back”; with respect
to the central nervous system, in 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
Toward 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
Cerebral cortex
The outermost layer of grey matter of the cerebral hemispheres
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 forehead
Horizontal section
A slice through the brain parallel to the ground
Sagittal section
A slice
through the brain parallel to the neuraxis
and perpendicular to the ground
Midsagittal plane
The plane through the
neuraxis perpendicular to the ground; divides the brain into two symmetrical halves.
Meninges
The three layers
of tissue that encase the central nervous
system: the dura mater, arachnoid membrane, and pia mater
Dura mater
The outermost of the meninges; tough and flexible
