GENERAL HISTOLOGY

Detailed explanation-1: -Paired structures having right and left members (e.g., the kidneys) are bilateral, whereas those occurring on one side only (e.g., the spleen) are unilateral.

Detailed explanation-2: -Bilateral. Refering to paired structures, one on each side. Ipsilateral. Refering to structures on the same side of the imaginary midline.

Detailed explanation-3: -Ipsilateral refers to structures on the same side of the body or brain (left or right), whereas contralateral refers to structures on opposite sides of the body.

Detailed explanation-4: -Dorsal Cavity. The dorsal cavity is at the posterior, or back, of the body, including both the head and the back of the trunk. The dorsal cavity is subdivided into the cranial and spinal cavities. The cranial cavity fills most of the upper part of the skull and contains the brain.

Detailed explanation-5: -To visualize both lungs, the heart, the spinal cord, and the ribs, a cut must be made through the transverse (horizontal) plane. This plane divides the body into superior and inferior portions.
