Exercise 1: The Language of Anatomy

Vocabulary flashcards covering standard anatomical position, planes, axes, sections, directional terms, body cavities, and anatomical regional terms.

Human Standard Anatomical Position

Refers to the position where the person is standing upright, feet slightly apart at shoulder width and parallel, toes directed forward, arms hanging at the side with palms facing up, and thumbs pointing away from the body.

Plane

A flat surface along which the body can be divided to show internal structures at different views, forming a three-dimensional perspective.

Axis

An imaginary line at right angles to the plane, about which the body can rotate.

Section

A two-dimensional surface of a three-dimensional structure that runs parallel to a plane.

Frontal / Coronal Plane

A plane that divides the body or organ into the back (posterior) and anterior (front).

Sagittal Plane

A plane that divides the body or organ into left and right sides.

Median / Midsagittal Plane

A plane that runs down the middle of the body, dividing it into equal left and right sides.

Parasagittal Section

Cuts parallel to the sagittal plane.

Transverse Plane

A plane that divides the body or organ into upper and lower portions; also known as a cross-section.

Anteroposterior Axis

An imaginary line that runs from head to sacral.

Dorsoventral Axis

An imaginary line that runs from the upper side (backside) to the lower side.

Transverse / Medio-lateral Axis

An imaginary line that runs from side to side.

Directional Term

Allows a precise description of the location of a specific body part in reference to another body part.

Anterior (Ventral)

Describes the front surface or toward the front of the body.

Posterior (Dorsal)

Describes the back surface or directed towards the back.

Superior (Cranial or Cephalic)

Describes a position above or higher than another part of the body.

Inferior (Caudal)

Describes a position below or lower than another part of the body.

Medial

Describes a position towards the midline of the body.

Lateral

Describes a position away from the midline of the body.

Intermediate

A position between a more medial and more lateral structure.

Proximal

A position close to the origin of the parts or near its point of attachment.

Distal

Describes a position that is away from the point of attachment.

Superficial

Describes a position closer to the surface of the body.

Deep

Describes a position farther from the surface of the body.

Body Cavity

Compartments that separate different structures in the body.

Cranial Cavity

A dorsal cavity component that houses and protects the brain.

Spinal Cavity

A dorsal cavity component extending from the cranial cavity that protects the spinal cord.

Thoracic Cavity

A ventral cavity division inside the rib cage containing the heart, lungs, and mediastinum.

Mediastinum

Structure within the thoracic cavity that separates the left and right lung.

Diaphragm

Structure that separates the thoracic and abdominopelvic cavity.

Abdominopelvic Cavity

A ventral cavity division containing the majority of the internal organs, composed of the abdominal cavity and pelvic cavity.

Abdominopelvic Quadrants

The four abdominal cavity divisions: Right upper quadrant (RUQ), Left upper quadrant (LUQ), Right lower quadrant (RLQ), and Left lower quadrant (LLQ).

Abdominopelvic Regions

The nine abdominal cavity regions: Right Hypochondriac, Epigastric, Left Hypochondriac, Right Lumbar, Umbilical, Left Lumbar, Right Iliac/Inguinal, Hypogastric, and Left Iliac/Inguinal.

Axilla (axillary)

Regional anatomical term referring to the armpit.

Brachium (brachial)

Regional anatomical term referring to the arm.

Antecubitis (antecubital)

Regional anatomical term referring to the front of the elbow.

Antebrachium (antebrachial)

Regional anatomical term referring to the forearm.

Carpus (carpal)

Regional anatomical term referring to the wrist.

Olecranon (olecanal)

Regional anatomical term referring to the back of the elbow.

Popliteus (popliteal)

Regional anatomical term referring to the back of the knee.

Sura (sural)

Regional anatomical term referring to the calf.

Planta (plantar)

Regional anatomical term referring to the sole of the foot.
