Anatomical Terms Quiz

Study Notes

Directional Terms

Superficial vs Deep: Refers to the relative position of structures; superficial means closer to the surface, while deep indicates further away from the surface.
Superior vs Inferior: In anatomical terms, superior describes a structure that is above another, and inferior refers to one that is below.
Ventral vs Dorsal: Ventral is synonymous with anterior (front) and dorsal with posterior (back).
Ipsilateral vs Contralateral: Ipsilateral refers to structures on the same side of the body, while contralateral pertains to structures on opposite sides.
Lateral vs Medial: Lateral denotes a position away from the midline of the body, and medial refers to a position toward the midline.
Distal vs Proximal: Distal describes structures further from the trunk of the body, whereas proximal indicates closeness to the trunk or point of attachment.
Intermediate: Accompanies the relative position between medial and lateral structures.

Anatomical Regions

Cephalic: Includes cranial (skull), facial (face), occipital (back of the head), frontal (forehead), orbital (eye sockets), otic (ears), nasal (nose), buccal (cheeks), oral (mouth), and mental (chin).
Cervical: Refers to the neck region.
Axillary: Pertains to the armpit area.
Acromial: Relates to the shoulder region.
Scapular: Indicates the area of the shoulder blade.
Thoracic: Encompasses the chest area, including the sternal region.
Abdominal: Refers to the belly area.
Coxal: Relates to the hip region.
Lumbar: Pertains to the lower back.
Inguinal: Indicates the groin area.
Pubic: Refers to the genital region.
Gluteal: Relates to the buttock area.
Sacral: Refers to the area between the hips.
Brachial: Related to the arm, with subdivisions: antecubital (front of the elbow), antebrachial (forearm), and olecranal (back of the elbow).
Manual: Pertains to the hand, including carpal (wrist), palmar (palm), and pollex (thumb).
Femoral: Refers to the thigh.
Patellar: Pertains to the knee.
Popliteal: Refers to the area behind the knee.
Crural: Relates to the leg.
Pedal: Refers to the foot, including tarsal (ankle), plantar (bottom of the foot), and hallux (big toe).

Sectional Planes

Sagittal: Divides the body into left and right portions.
Midsagittal or Median: Cuts the body into equal left and right halves; compared with parasagittal which divides into unequal parts.
Frontal or Coronal: Divides the body into anterior (front) and posterior (back) sections.
Transverse or Horizontal/Cross: Cuts the body into superior (upper) and inferior (lower) parts.
Oblique: Diagonal cuts through the body.

Body Cavities

Dorsal Cavity: Comprised of cranial (houses the brain) and vertebral (houses the spinal cord) cavities.
Ventral Cavity: Contains two main subdivisions: abdominopelvic (further divided into abdominal and pelvic cavities) and thoracic (includes pleural and mediastinum, which contains the pericardial cavity).

Abdominopelvic Quadrants

Right Upper Quadrant (RUQ): Contains parts of the liver and gallbladder.
Left Upper Quadrant (LUQ): Houses the stomach and spleen.
Right Lower Quadrant (RLQ): Contains the appendix and parts of the intestines.
Left Lower Quadrant (LLQ): Includes parts of the intestines and reproductive organs.

Abdominopelvic Regions

Right and Left Hypochondriac: Located below the ribs on either side.
Epigastric: Found above the stomach.
Right and Left Lumbar: Located in the lower back area.
Umbilical: Central region around the navel.
Right and Left Iliac: Also known as inguinal regions, found in the lower sides.
Hypogastric: Located below the umbilical region.

Important Metric Units and Conversions

Metric Units: Used for measuring length, area, volume, mass, and temperature.
Foundational Units:
- Meters (m) for length; approximately equal to three feet or one yard.
- Meters squared (m²) for area; relates to two dimensions.
- Liters (l or L) for volume; alternatively, cubic meters (m³) and cubic centimeters (cc).
- Grams (g) for mass; roughly equal to the weight of a paperclip.
- Celsius (C) for temperature; freezing point of water is 0°C, boiling point is 100°C.
Metric Prefixes:
- Milli (m): One-thousandth of a basic unit.
- Centi (c): One-hundredth of a basic unit.
- Kilo (k): One hundred of a basic unit.
Example Conversion: 1 mm equals one-thousandth of a meter.
