Anatomical Directions and Opposites
- Name the directions and their opposites as used in Anatomy practice:
- Superior (cranial) — toward the head; Inferior (caudal) — away from the head. These terms deal with the Axial Region (trunk).
- Deep — internal; Superficial — external.
- Medial — toward the midline; Lateral — away from the midline.
- Proximal — closer to the point of attachment (e.g., shoulder or trunk) on limbs; Distal — farther from the point of attachment. These terms deal only with the Appendicular Region (Limbs).
- Anterior (Ventral) — toward the front; Posterior (Dorsal) — toward the back.
- Directional examples from the transcript:
- From the wrist to the elbow: Proximal.
- From the nose to the ear: Lateral.
- From the umbilicus (navel) to the chin: Superior.
- From the hip to the ankle: Distal.
Planes of the Body
- Transverse (Horizontal) Plane: Divides the body into superior and inferior portions.
- Frontal (Coronal) Plane: Divides the body into anterior and posterior portions.
- Sagittal Plane: Divides the body into right and left portions.
- Parasagittal Plane: Divides the body into unequal right and left portions.
- Midsagittal Plane: Divides the body into equal right and left halves.
- Oblique Plane: Any plane that passes through the body at an angle.
Planes – Quick References from the Transcript
- Page 27: Transverse Plane — divides into superior/inferior.
- Page 31: Frontal (Coronal) Plane — divides into anterior/posterior.
- Page 33: Sagittal or Parasagittal Plane — sagittal divides into right/left; parasagittal divides into unequal right/left portions; midsagittal divides into equal halves.
- Page 29/30/33: Oblique Plane and other plane references.
Body Cavities and Dorsal/Ventral Aspects
- Dorsal Aspect (Posterior body cavity) contains two parts:
- Cranial Cavity (contains the brain)
- Vertebral Canal (contains the spinal cord)
- Ventral (anterior) Body Cavity contains the major front-facing cavities:
- Thoracic Cavity (above the diaphragm)
- Abdominal Cavity (below the diaphragm; houses many digestive organs)
- Pelvic Cavity (reproductive and some urinary organs)
- Additional notes from the transcript:
- The Cranial Cavity and Vertebral Canal are the two parts of the dorsal aspect.
- Thoracic Cavity includes organs such as lungs and heart; other structures listed as acceptable include trachea, bronchi, esophagus, thymus, blood vessels, nerves and lymph nodes/vessels.
Body Regions and Quadrants
- Axial Region vs Appendicular Region:
- Axial Region includes head, neck, trunk.
- Appendicular Region includes the limbs (limb girdles are part of the appendicular region).
- Color-coded regional terms from the transcript (example notes):
- Blue region: Appendicular Region (Is the blue region axial or appendicular? APPENDICULAR).
- Tan region: Axial Region (Is this region axial? Yes).
- Regional terms (examples mentioned in the transcript): Cervical, Femoral, Brachial, Gluteal, Deltoid, Frontal, Orbital, Nasal, Mental, Sternal, Mammary, Axillary, Antebrachial, Coxal, Palmar, Digital, Patellar, Crural, Dorsum of the hand/foot, Plantar surface, Calcaneal, Sural, Occipital, Olecranal, Popliteal, Pes, Tarsal, Pubic, Inguinal, Crural, Perineal, Manus (hand), etc.
- Specific regions and their typical locations:
- Cervical — neck
- Femoral — thigh
- Brachial — arm
- Gluteal — buttock
- Deltoid — shoulder
- Dorsum of the hand — back of the hand
- Dorsum of the foot — top of the foot
- Palmar — palm
- Plantar — sole
- Anterior view vs Posterior view: The transcript provides lists labeled as (a) Anterior view and (b) Posterior view with many terms as examples.
Abdominal Quadrants and Regions
- Abdominal Quadrants (four):
- Upper Right (URQ)
- Upper Left (ULQ)
- Lower Right (LRQ)
- Lower Left (LLQ)
- Abdominal Regions (nine-region model):
- Right Hypochondriac, Epigastric, Left Hypochondriac
- Right Lumbar, Umbilical, Left Lumbar
- Right Iliac (Inguinal), Hypogastric (Pelvic), Left Iliac (Inguinal)
Abdominal Regions – Sample Terms from the Transcript

- Rt. Lumbar, Lt. Lumbar, Umbilical
- Rt. Iliac (Inguinal), Lt. Iliac (Inguinal), Hypogastric (Pelvic)
Anatomical Position
- Supine Position: lying on the back; the term contains the word “up” (supine).
- Prone Position: lying on the abdomen; belly down and back up.
- Anatomical Position (universal reference position):
- Patient standing erect
- Feet flat on the floor
- Arms at the sides
- Palms and eyes facing the observer
Major Body Cavities and Organs – Quick References
- Thoracic Cavity (part of Ventral cavity):
- Major organs: Lungs, Heart (and other structures like trachea, bronchi, esophagus, thymus, blood vessels, nerves, lymph nodes/vessels).
- Abdominal Cavity (part of Ventral cavity):
- Contains major digestive organs (specific organs not exhaustively listed in the transcript).
- Pelvic Cavity (part of Ventral cavity):
- Contains reproductive and some urinary organs (not exhaustively listed).
- Dorsal Aspect includes Cranial Cavity (brain) and Vertebral Canal (spinal cord).
Body Systems (as named in the transcript)
- Respiratory System:
- Nose, Nasal cavity, Pharynx, Larynx, Trachea, Lungs, Diaphragm
- Endocrine System:
- Parathyroid glands (posterior surface of thyroid)
- Ovaries (female)
- Hormones as chemical messengers; endocrine glands and tissues
- Skeletal System:
- Bones, Cartilage, Ligaments, Tendons (T appears in the transcript as a fragment; typically would include tendons as connective tissue; the transcript lists Bones, Cartilage, Ligaments with a stray “T”).
- Nervous System:
- Brain, Spinal cord, Cranial nerves, Peripheral nerves
Practice Highlights and Examples
- Directional practice questions from the transcript (examples):
- From wrist to elbow: Proximal
- From nose to ear: Lateral
- From umbilicus to chin: Superior
- From hip to ankle: Distal
- Planes practice:
- Which plane divides the body into superior and inferior portions? Transverse

- Which plane divides into right and left? Sagittal; Midsagittal equals equal halves; Parasagittal equals unequal halves
- Dorsal vs Ventral structure identification:

Notes on Specific Transcript Details and Annotations
- The transcript provides multiple pages enumerating terms; some entries are repeats or variants (e.g., several lists of regional terms with anterior and posterior views).
- Some items in the transcript appear to be color-coded (blue vs tan regions) to indicate axial vs appendicular classifications; the example notes indicate blue regions correspond to Appendicular and tan regions to Axial in that exercise context, though one item lists Gluteal as AXIAL which differs from standard anatomy conventions.
- The transcript includes explicit practice prompts and answers for directional terms, planes, and body positions, which are included here as direct-reference notes and examples to help memorize the material.
