Lec slide 6

Question 1

Interoceptors

Answer 1

transduce (to convert smtg into another form) info from within body.

• transfer to electrical, hormonal, or other non-neural signals

Question 2

Exteroceptors

Answer 2

transduce info from environment

Question 3

Proprioceptors. What do and what are they called.

Answer 3

info about configuration of body segments (where you are in space e.g. joint angles)

• Muscle spindles
• GTO’s

Question 4

do receptors respond to chemical or mechanical stimuli?

Answer 4

one, the other, or both

Question 5

spatial summation vs temporal summation.

Answer 5

Spatial - multiple presynaptic neurons have EPSP’s, or IPSP’s that converge at the same neuron causing action potential.

Temporal - one presynaptic neuron firing signals to a postsynaptic neuron and the rate matters.

Question 6

does the same synaptic input to a smaller motor neuron create a larger or smaller graded potential

Answer 6

larger, smaller are more easily influenced/have lower threshold
