Question | Answer |
Mechanoreceptors | respond to touch, pressure, vibration, stretch and itch |
thermorecptors | sensitive to changes in temperature |
photoreceptors | respond to light energy |
chemoreceptors | respond to chemicals |
nociceptors | sinsitive to pain-causing stimuli |
unencapsulated simple receptors | free nerve endings, merkel discs, hair follicle receptors |
free nerve endings | Pain receptor, extroceptors, introceptors. Nociceptors, thermoreceptors. |
merkel discs | Pressure receptor extroceptors, mechanoreceptors slowly adapting |
hari follicsls | Light pressure or hair movement, extroceptors, mechanoreceptors rapidly adapting |
encapsulated receptors | meissner's corpuscles, pacinian corpusles |
meissner's corpuscles | Light touch, extroceptors, mechanoreceptors (light pressure, discriminative touch, vibration) rapidly adapting |
pacinian corpuscles | Deep Pressure, extroceptors, introceptors, Mechanoreceptors (deep pressure, stretch, vibration of high frequency) rapidly adapting. |
ruffini's corpuscles | Skin Stretching receptor, extroceptors, mechanoreceptors, slowly or non adapting |
muscles spindles | Changes in length of Muscle, proprioceptors, mechanoreceptors |
Golgi tendon organs | stretching |
Patellar Reflex | Knee reflex, stretch reflex, contains interneurons and antagonistic muscles inhibition |
Achilles reflex | ankle reflex, stretch reflex |
Hearing acuity test | how far we were able to hear the clock...the threshold of audibility was indefinite |
hearing localization test | localizing sound was easy from the front and the sides but was difficult or impossible from the back. |
weber test | a test to see if there is hearing loss in one ear. if the tuning fork is able to strike and be heard equally then there is not unequal hearing loss |
rinne test | a test to compare bone conduction vs. air conduction of sound. The Air conduction of sound should be better sound |
Cervical plexes | Phrenic nerve, c3-c5, diaphragm |
axillary nerve | c5, c6, deltoid and some skin, brachial plexus |
musculocutaneous nerve | brachial plexus, c5-c7, muscles (arm) |
median nerve | brachial plexus, c,8 and t1 and c5-c7, muscles and flexor group of anterior forearm, skin of lateral 2/3rs of hand |
ulnar nerve | brachial plexus, c8-t1, muscular branches, flexor muscles in anterior forearm, hand muscles |
radial nerve | brachial plexus, c5-c8 and t1, posterior muscles of arm, triceps brachioradialis |
Femoral nerve | Lumbar plexus, L2-L4, skin of anterior and medial thigh, meadial leg and foot, hip and knee joints. Motor to quads. |
obturator nerve | lumbar plexus, L2-l4, motor to adductor magnus, longus and brevis muscles, sensory for medial thigh |
Sciatic nerve | Sacral plexus, l4, l5, s1-s3, back of the leg |
Tibial nerve | sacral plexus, l4-s3, skin of posterior surface of leg and sole of foot. motor branches back of the thigh |
common fibular nerve | sacral plexus, l4-s2, skin of the anterior surface of leg and dorsum of foot |
pudendal nerve | sacral plexus s2-s4, genitalia |
