Procedure: extension of the elbow tests: radial nerve
cutaneous reflex, the plantar reflex and Babinski's sign
Procedure: planter flexion and toe flexion
If you are unable to elicit a response from your patient you can have them try several things. What are they
1) Have them grip their hands together and try to pull apart 2) Have them count backwards from 100 by 7's out loud 3) Have them clench their teeth together really hard 4) Have them say the alphabet backwards out loud
4 cutaneous sensations
warmth, cold, touch, pain (also pressure, itch and tickle)
sensation: sustained pressure location: deep in dermis, hypodermis
sensation: changes in texture, slow vibrations location: papillary dermis
sensation: deep pressure, fast vibrations location: deep in dermis
where is touch receptor density dense?
hands, lips, and face
How is the density of touch receptors tested?
By using the test-point threshold test. A calipers w/2 points is applied w/equal pressure to the skin. Subject is asked if 2 distinct points can be felt. The caliper points are moved closer together and the subject retested until only 1 point can be felt
ability of our sensory receptors to respond strongly to acute changes and then stop responding when these stimuli become constant
