Dissection Terminology & Safety

Tools Dissecting pan Scalpel (blade) Pins Forceps Probe Teasing needle Scissors

Scalpel- used to make incisions Pins- used to hold an area open or pinned back Scissors- used to cut through tissue.

Pan- holds specimen Forceps- to grasp at structures Probe-to search for structures Teasing Needle- for gently scraping tissue.

Terms

DORSAL- “back” VENTRAL- “belly”

SUPERIOR- “above” INFERIOR- “below”

ANTERIOR- “front” POSTERIOR- “rear” sometimes called caudal.

-relative location: PROXIMAL-”near” DISTAL-”far”

SUPERFICIAL- “near surface” DEEP- “below the surface”

Planes of Symmetry TRANSVERSE- bisects top & bottom halves. SAGITTAL- bisects left & right sides. LATERAL- “side” MEDIAN- “middle”

PELVIC- “hip region” PECTORAL- “chest region”

Safety Why should you be careful with scalpels, scissors & pins? Why should you wear gloves & goggles? Why should long hair be tied back? Why should you avoid wearing open-toe shoes? Why is there no food or drink allowed in a lab? Why is focus & appropriate behavior important in a dissection laboratory?
