II. SENSORY PHYSIOLOGY<\/strong><\/p>\n

A. Sensation<\/strong><\/p>\n

1. State of external\/internal awareness<\/p>\n

2. Stimulus<\/p>\n

3. Receptor<\/p>\n

4. Nerve impulse to brain<\/p>\n

B. Characteristics of sensations<\/p>\n

1. Projection – phantom pain<\/p>\n

2. Adaptation<\/p>\n

3. Afterimages<\/p>\n

4. Modality<\/p>\n

Can discern one sensation from another<\/em><\/p>\n

C. Receptors<\/p>\n

1. Dendrites [organs]\n

2. Generator potential<\/p>\n

D. Classification of receptors<\/p>\n

1. Location of stimulus<\/p>\n

a. Exteroceptors<\/p>\n

b. Enteroceptors = visceroceptors<\/p>\n

c. Proprioceptors<\/p>\n

Receptors for muscle sense<\/em><\/p>\n

2. Type of stimulus<\/p>\n

a. Mechanoreceptors<\/p>\n

b. Thermoreceptors<\/p>\n

c. Chemoreceptors<\/p>\n

d. Photoreceptors<\/p>\n

e. Nociceptors<\/p>\n

Pain receptors<\/em><\/p>\n

E. Cutaneous sensations<\/p>\n

1. Receptor fields [area skin whose stimulation results in nerve impulse]\n

a. 2 point discrimination \/ threshold<\/p>\n

Smallest distance that 2 distinct points can be detected<\/em><\/p>\n

b. Lateral inhibition<\/p>\n

Sharpening of the sensation<\/em><\/p>\n

2. Tactile sensations<\/p>\n

a. Meissner’s corpuscles<\/p>\n

Touch corpuscles<\/em><\/p>\n

b. Hair root plexus<\/p>\n

c. Free nerve endings<\/p>\n

3. Pressure sensations<\/p>\n

a. Pacinian = Lamellated corpuscles<\/p>\n

4. Thermal sensations<\/p>\n

a. Free nerve endings<\/p>\n

5. Pain sensation<\/p>\n

a. Free nerve endings<\/p>\n

b. Referred pain<\/p>\n

F. Proprioceptive sensations (kinesthetic sense)<\/p>\n

1. Muscle spindles; intrafusal fibers<\/p>\n

stretch receptors<\/em><\/p>\n

2. Tendon organs =Golgi tendon organs<\/p>\n

contraction receptors<\/em><\/p>\n

3. Misc. joint receptors<\/p>\n
