Planes of Section: one of three different plans of section used when the nervous system is imaged “radiologically.” (Blumenfeld, 17)Ĭoronal: pertaining to a plane containing a line parallel to the long axis of the subject's body and in addition presenting anterior and posterior views on each side of it. (Fisch, 274) For example, undersurface of the “frontal lobe.” Undersurfaces: surfaces of the brain (especially of the “cerebrum”) seen from below. (Kolb, 39) Surfaces of the brain (especially of the “cerebrum”) seen from a “sagittal” perspective (Fisch, 273) Noun - ‘median.’ Also referred to as ‘medial aspect.’
(OxfordMed) Structures found toward the brain's midline. Relating to or denoting the parts of the body that are closest to the median plane of the body. Medial: relating to or situated in the central region of an organ, tissue, or the body. In the “sagittal plane." (OxfordMed) Surfaces of the brain (especially of the "cerebrum”) seen from above and from the side. Relating to the region or parts of the body that are furthest from the "medial" plane. (Kolb, 39) Situated at or relating to the side of an organ or organism. (Kolb, 39) Editor’s note - from the Latin word ‘venter’ for ‘beak.’ Indicating ‘toward the earth.’īrain Surfaces: editor’s note: views of the brain from the top and bottom and from a sagittal plane of section. (NCIt) Structures located toward the bottom of the human brain or one of its parts. Ventral: pertaining to the underside or lower surface of the body opposite of dorsal. (NCIt) Editor’s note - from the Latin word for ‘beak.’ (Patestas, 4) Toward the muzzle in the head. (Blumenfeld, 16) Toward the nose, proceeding toward a higher position the opposite of caudal. (Kolb, 39) Editor’s note - from the Latin word for ‘back’ as in the location of a shark’s fin. (NCIt) Editor’s note - from the Latin word for ‘tail.’ĭorsal: pertaining to the back or upper surface of the body opposite of “ventral.” (NCIt) Structures found on the top of the human brain or on the top of some other structure within the brain.
(Patestas, 4) Constituting or relating to a tail situated near the tail. (This is because, in humans) the nervous system makes a bend of nearly 90 degrees somewhere between the “forebrain” and the “spinal cord.” (Blumenfeld, 16)Ĭaudal: toward the tail (proceeding to a lower position the opposite of rostral).
Below the midbrain there is a rotation (of each axis) of 90 degrees (clockwise). (NCIt)Īxes - Rostral to Caudal: dorsal, ventral, rostral, and caudal (descriptions) vary according to a structure’s position in relation to the “midbrain.” Above the midbrain the orientation used is similar to that used with animals whose nervous system is linear in orientation. (Kolb, 39) Pertaining to a point above a given reference point. Superior: vertical axis (like the ‘y-axis’). At or near the hind end in ‘quadrupeds’ or toward the spine in “primates.” (NCIt) (Kolb, 39) In human anatomy, has to do with the back of a structure, or a structure found toward the back of the body. Those (structures) located toward the back of the brain. Posterior: horizontal (like the ‘x-axis’). Occasionally, the terms superior and inferior are used to refer to structures that are located "dorsally" or "ventrally." (Kolb, 39) Pertaining to a point below a given reference point. Inferior: vertical axis (like the ‘y-axis’).
(NCIt) Structures located near the front of the brain. (Oxford) In “human anatomy,” has to do with the front of a structure, or a structure found toward the front of the body. Situated near the front of the body, or nearer to the head, forepart, etc. (Kolb, 39)Īnterior: horizontal axis (like the ‘x-axis’). (Fisch, 4) These terms do not label structures according to their importance, just their location. (NCIt) Plural - ‘axes.’Īxes - Anterior to Posterior: superior, inferior, anterior, and posterior (descriptions) are consistent throughout the nervous system that is, top is always superior, (bottom is always inferior) etc. Axis: a straight line through a body or figure that satisfies certain conditions.
