Midsagittal: along the midline; left and right sections are equal. Planes and sections: sagittal (medial): vertically divides body into left and right sections, transverse (horizontal; cross): horizontally divides the body into superior and inferior sections, frontal (coronal): vertically divides the body into anterior and posterior sections. Medulla (medullary): inside region: axial: main axis (head, abdomen, chest) Appendicular: appendages (arms, legs: afferent: towards the point of reference. Efferent: away from the point of reference (e for exit: ipsilateral: on the same side of the body as the point of reference; pertaining to or. Contralateral: on the opposite side of the body as the point of reference; pertaining to or situated on or affecting the opposite side of the body. Vasoconstriction: tightening = less blood flow = worse perfusion. Serous cavity: visceral: inner membrane; adheres to surface of organ/structure, parietal: outer membrane. Both relate to double layered serous membranes (serosa) found lining the walls or organs of the ventral (anterior) cavity.
