DIFFERENTIATE BETWEEN INTEROCEPTORS AND EXTEROCEPTORS RELATIVE TO LOCATION AND STIMULUS SOURCE

INTEROCEPTOR:RESPONDS TO STIMULI ARISING FROM WITHIN THE BODY.
EXTEROCEPTOR: RESPONDS TO STIMULI OUTSIDE IN THE EXTERNAL ENVIRONMENT, THESE ARE FOUND CLOSEST TO THE BODY SURFACE

BACKING INTO A SUN-HEATED IRON RAILING

EXTEROCEPTOR; PAIN RECEPTOR

SOMEONE STEPS ON YOUR FOOT

EXTEROCEPTOR; PAIN RECEPTOR

READING A BOOK

EXTEROCEPTOR; PHOTORECEPTORS

LEANING ON YOUR ELBOWS

EXTEROCEPTOR AND INTEROCEPTOR; PACINIAN CORPUSCLES AND PROPRIOCEPTOR

DOING SIT-UPS

INTEROCEPTOR; PROPRIOCEPTORS

THE "TOO FULL" SENSATION

INTEROCEPTORS; VISCERAL (STRETCH) RECEPTORS

SEASICKNESS

EXTEROCEPTOR; EQUILIBRIUM APPARATUS OF THE INNER EAR

EXPLAIN HOW THE SENSORY RECEPTORS ACT AS TRANSDUCERS

THE CHANGE ENVIRONMENTAL STIMULI INTO AFFERENT NERVE IMPULSES.

DEFINE STIMULUS

A STIMULUS IS ANYTHING THAT CAN TRIGGER A RESPONSE (ACTION POTENTIAL)

WHAT WAS DEMONSTRATED BY THE TWO-POINT DISCRIMINATION TEST?

THE DEMONSTRATION IS TESTING TOUCH RECEPTORS, AND HOW THEY ARE DISTRIBUTED IN DIFFERENT AREAS OF THE BODY.

HOW WELL DID YOUR RESULTS CORRESPOND TO YOUR PREDICTIONS?

MY PREDICTIONS WERE WAY OFF; THE SPACE (DISTANCE) BETWEEN THE TOUCH RECEPTORS WERE GREATER THAN EXPECTED.

WHAT IS THE RELATIONSHIP BETWEEN THE ACCURACY OF THE SUBJECT'S TACTILE LOCALIZATION AND THE RESULTS OF THE TWO-POINT DISCRIMINATION TEST?

THE DISTANCE OF BOTH WERE NOT CLOSELY SIMILAR

Ok, so you’re using my notecards which is great. I am glad I could help you out cause I wish I had someone to help me out when I took this course. I know Anatomy is super hard.

I only ask that if you find these notecards helpful, you join Easy Notecards and create at least one notecard set to help others out. It can be for any subject or class. Thanks and don’t forget to rate my helpfulness!

DEFINE PUNCTATE DISTRIBUTION

THE CLUSTERING AT CERTAIN POINTS OF SENSORY RECEPTORS, THEY ARE NOT DISTRIBUTED UNIFORMLY

WHICH CUTANEOUS RECEPTORS ARE THE MOST NUMEROUS?

PAIN RECEPTORS

WHICH TWO BODY AREAS TESTED WERE MOST SENSATIVE TO TOUCH?

LIPS, FINGERTIPS

WHICH TWO BODY AREAS TESTED WERE LEAST SENSATIVE TO TOUCH?

VENTRAL FOREARM, BACK OF NECK

WHICH APPEAR TO BE MORE NUMEROUS - RECEPTORS THAT RESPOND TO COLD OR TO HEAT?

COLD

WHERE WOULD REFERRED PAIN APPEAR IF THE FOLLOWING ORGANS WERE RECEIVING PAINFUL STIMULI - GALLBLADDER, KIDNEYS, AND APPENDIX?

GALLBLADDER: RIGHT INFERIOR THORAX
KIDNEYS: LUMBAR
APPENDIX: RIGHT LOWER QUADRANT

WHERE WAS REFERRED PAIN FELT WHEN THE ELBOW WAS IMMERSED IN ICE WATER DURING THE LABORATORY EXPERIMENT?

UPPER ARM (MEDIAL)

WHAT REGION OF THE CEREBRUM INTERPRETS THE KIND AND INTENSITY OF STIMULI THAT CAUSE CUTANEOUS SENSATIONS?

SOMATOSENSORY AREA

DEFINE ADAPTATION OF SENSORY RECEPTORS

WHEN THE RECEPTOR DISCHARGE SLOWS AND CONSCIOUS AWARENESS OF THE STIMULUS DECLINES OR IS LOST UNTIL SOME TYPE OF STIMULUS CHANGE OCCURS

WHY IS IT ADVANTAGEOUS TO HAVE PAIN RECEPTORS THAT ARE SENSITIVE TO ALL VIGOROUS STIMULI, WHETHER HEAT, COLD, OR PRESSURE?

TO WARN YOU QUICKLY OF HARM OR DANGERS THAT ARE HAPPENING TO YOUR BODY.

WHY IS THE NONADAPTABILITY OF PAIN RECEPTORS IMPORTANT?

IF WE COULD ADAPT TO PAIN EASILY WE WOULD NOT RECOGNIZE CONTINUED CONDITIONS THAT COULD EFFECT US. AND PAIN IS ALSO THE ONLY SENSATION THAT IS CONSIDERED A SYMPTOM SO IT IS HELPFUL.

IMAGINE YOURSELF WITHOUT ANY CUTANEOUS SENSE ORGANS. WHY MIGHT THIS BE VERY DANGEROUS?

BECAUSE YOU WILL NOT KNOW IF YOU ARE IN DANGER. IF YOU CUT YOURSELF BAD YOU COULD GET AN INFECTION, OR YOU COULD DIE WITHOUT EVEN BEING ABLE TO DETECT IT, PROTECT YOURSELF, OR GET MEDICAL CARE IN TIME.

DEFINE REFERRED PAIN

THE PHENOMENON OF PAIN PERCEIVED AT A SITE ADJACENT TO OR AT A DISTANCE FROM THE SITE OF AN INJURED ORGAN.

WHAT IS THE PROBABLE EXPLANATION FOR REFERRED PAIN?

"REFERRED PAIN HAPPENS WHEN NERVE FIBERS FROM REGIONS OF HIGH SENSORY INPUT AND NERVE FIBERS FROM REGIONS OF NORMALLY LOW SENSORY INPUT HAPPEN TO CONVERGE ON THE SAME LEVELS OF THE SPINAL CORD."
