The neurons

The middle ear

The accessory structures

The peripheral sensory components

The receptor cells that are bare nerve endings

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

Slowly adapting receptors

Type II and III sensory systems

Type II sensory systems

Type I sensory systems

Rapidly adapting receptors

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.

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

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

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

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
