RGCs conduct information at different rates unlike other sensory afferent neurons.

RGCs have receptive fields (RFs) with a centre-surround organization.

Some RGCs cross over in the brain unlike other primary sensory afferent neurons which cross over in the spinal cord.

RGCs are either rapidly or slowly adapting neurons.

Translation, the process of moving stimuli efficiently to the receptor surface is a role carried out by

The neurons

The middle ear

The accessory structures

The peripheral sensory components

The receptor cells that are bare nerve endings

Transduction is a process that always involves

The production of a change in the resting membrane potential of the receptive structure

The production of a resting mebrane potential in the receptive structure

The production of action potentials in the receptive structure

Amplification of the signal in the receptive structure

G proteins

Sinusoidal or dynamic stimuli can be signalled best by

Slowly adapting receptors

Type II and III sensory systems

Type II sensory systems

Type I sensory systems

Rapidly adapting receptors

The two types of ion channels found in sensory receptors are:

Chemically-gated and voltage-gated channels.

Voltage-gated and light-gated channels.

Light-gated and sound-gated channels.

Voltage-gated and mechanically-gated channels.

Mechanically-gated and chemically-gated channels.

Receptor or Generator potentials and Action Potentials are similar in that:

they are both all-or-none responses.

their duration varies between 1 and 2 milliseconds.

their amplitudes adapt as the stimulus is maintained.

they are produced by conductance changes due to the opening or closing of channels.

their size is graded to the strength of the stimulus.

Transmission in peripheral sensory systems is the process

Of converting the stimulus energy to produce a receptor potential

Of amplifying the stimulus energy efficiently to activate receptors

Of moving the stimulus energy efficiently from the external environment to the receptor surafce

Of relaying of sensory information via APs in neurons

Of blocking off background signals during maintained stimuli

Receptors are electrically polarized cells because

Accessory structures allow the stimulus energy to fall efficiently on receptors

Ion channels are always open

G proteins allow the movement of ions at rest

There is selective permeability for transmembrane flow of ions

They have stretch-activated or G protein gated ion channels

Receptor potentials in receptor cells and EPSPs in neurons are similar in that

They both spread electrotonically to trigger an AP close to the site where they occur

They both act over very fast time scales because of the ion channels involved

They both are all-or-none responses

They both are decreases in the RMP of the respective structures

They both are longer lasting events that can sum

In receptors, the appropriate stimulus results in a change in the resting membrane potential because of changes in ionic movement through

voltage-gated or mechanically-gated channels

activated molecules or gated molecules

gated or passive channels

the receptor channels or generator channels

mechanically-gated or chemically-gated channels
