Study Notes

Directional Terms

Transverse/HORIZONTAL plane divides the body into superior (upper) and inferior (lower) parts.
Superior/Cephalic/Cranial: Towards the head; e.g., heart is superior to liver.
Inferior/Caudal: Away from the head; e.g., stomach is inferior to lungs.
Anterior/Ventral: Nearer to the front; e.g., sternum is anterior to heart.
Posterior/Dorsal: Nearer to the back; e.g., esophagus is posterior to trachea.
Medial: Near to the midline; e.g., ulna is medial to radius.
Lateral: Away from the midline; e.g., lungs are lateral to heart.
Intermediate: Between two structures; e.g., transverse colon is intermediate to ascending and descending colon.
Ipsilateral: Same side of the body; e.g., facial nerve affects the same side in Bell's palsy.
Contralateral: Opposite side of the body; e.g., stroke affecting one side can cause effects on the opposite side.
Proximal: Near the origin of a structure; e.g., elbow is proximal to wrist.
Distal: Far from the origin; e.g., fingers are distal to the wrist.
Superficial/External: Towards or on the surface; e.g., ribs are superficial to lungs.
Deep/Internal: Away from the surface; e.g., ribs are deep to the skin.

Skeletal System: Supports body structure; contains 206 bones and produces blood cells.
Nervous System: Communication network; comprises central (brain, spinal cord) and peripheral systems.
Immune System: Defends against infections; includes lymph nodes, bone marrow, and spleen.
Urinary System: Filters blood and removes waste; includes kidneys, bladder, and urethra.
