SURFACE ANATOMY



Head and Neck


nasion (junction frontal and nasal bones)
glabella
superciliary arch (above supraorbital margin)
temporal line (curves up and back)
parietal eminence (above posterior temporal line)
greatest transverse diameter (betw parietal eminences)
median nuchal furrow (below ext occipital protuberence, overlying ligamentum nuchae)
inion (tip ext occipital protuberence)
maximum occipital point (greatest convex curvature above ext occasionally protuberence)
lambda (above max occasionally point)
superior nuchal line (lat from ext occasionally prot)
anterior triangle (betw midline, SCM, mandible))
posterior triangle (betw SCM, trapezius, clavicle)

Abdomen


xiphisternal plane (horizontal)
transpyloric plane (halfway between suprasternal notch and symphysis pubis)
subcostal plane (10th costal cartilages)
supracristal plane (highest iliac crest)
mid-clavicular/lateral/mammary lines (>mid between ASIS and symphysis pubis)
abdominal regions (xiphoid and symphysis pubis in 1/3s, mid-clavicular lines) = epigastrium, R&L hypochondrium/ subcostal, umbilical/periumbilical, R&L lumbar, hypogastrium/suprapubic, R&L iliac region/fossa

Back


median furrow (external occipital protuberance > natal cleft)
sacral dimple (PSIS)

Limbs


infraclavicular fossa = deltopectoral triangle (betw pectoralis major and deltoid; cephalic v)
anatomical snuffbox = radial fossa (extensor pollicus longus, extensor pollicus brevis/abductor pollicus longus, styloid process radius, trapezium/scaphoid; radial a, cephalic v, dorsal cutaneous br of radial n)
proximal transverse wrist skin crease (ant line of the wrist joint)
distal trans wrist skin crease (proximal carpal bones)
lateral longitudinal arch of the foot
medial longitudinal arch = instep
