Anatomy Day 1: Terms, Planes, Quadrants & Osmosis

The skin is __ to the muscles.

Superficial (closer to surface of body)

Which plane divides the body into superior and inferior parts?

Transverse

Which plane divides the body into anterior and posterior parts?

Frontal / coronal

The elbow is __ to the wrist.

proximal: the shoulder is closer to the elbow (the attachment point) whereas the wrist is further

Appendix is typically in which quadrant?

Right lower quadrant (RLQ)

Name the center region of the nine-region map.

Umbilical

Water leaves a cell sitting in a __ solution.

Hypertonic

A cell swells and may burst in a __ solution.

Hypotonic

Superior

Toward the head / above

Inferior

Toward the feet / below

Medial

Toward the midline

Lateral

Away from the midline

Proximal (limbs only)

Closer to the trunk

Distal (limbs only)

Farther from the trunk

Superficial

Toward the body surface

Deep

Away from the surface

Sagittal plane

Cuts the body into left vs. right sections

Frontal (coronal) plane

Cuts the body into anterior vs. posterior sections

Transverse (horizontal) plane

Cuts the body into superior vs. inferior sections

Right Upper Quadrant (RUQ)

Contains liver, gallbladder, and part of colon

Left Upper Quadrant (LUQ)

Contains stomach, spleen, and tail of pancreas

Right Lower Quadrant (RLQ)

Contains appendix, cecum, and right ovary

Left Lower Quadrant (LLQ)

Contains sigmoid colon and left ovary

Hypertonic solution

More solute outside; water moves out, cell shrinks/crenates

Hypotonic solution

Less solute outside; water moves in, cell swells/lyses

Isotonic solution

Same solute; no net water movement, normal shape
