what is a sensory receptor and what is an example of one?

In the sensory receptors called “encapsulated nerve endings,” what is the “capsule” made of?

Receptor cells that are neurons with sensory dendrites are faster than receptor cells that are separate from neurons. Why is that, and why might that be important in, for example, the sense of touch versus vision?

Identify five kinds of sensory receptors based on the type of energy they transduce. What is the specific function of each?

The sensory systems are complex and have the amazing ability to respond to different types of environmental stimuli. What is one aspect of the sensory systems we have looked at (gustatory, olfactory, or visual) that you found particularly interesting and would like to know more about?

what is  an example of a sensory neuron being changed by external physical stimulation?

In the process of sensory coding    Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger.   The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination.    Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity.   A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.

Auditory neural signals are sent when HAIR CELLS in our inner ears open ion channels along their plasma membranes to trigger action potentials. What specifically happens to the hair cells that causes ion channels to open?

Sensory receptor cells transduce physical or chemical stimuli: a) by limiting action potentials b) from chemical to electrical energy c) from an action potential into a synaptic potential d) by summing incoming action potentials e) into a change in the membrane potential of the sensory receptor cells

What are the general locations and functions of primary, secondary, and tertiary neurons in sensory pathways?
