Question
Chapter 10.5, Problem 21CC
Summary Introduction
To determine: The type of ion and its movement direction to facilitate depolarization when the ion channels in the stereocilia open up.
Introduction: Stereocilia are the organelles, present in the inner ear that respond to the mechanical stimuli, for example, fluid motion, hearing, and balance. They share the common features with intestinal microvilli and are 10-50 micrometers in length.

If light strikes only one receptor, what is the net effect (excitatory or inhibitory) on the nearest bipolar cell that is directly connected to that receptor? What is the effect on bipolar cells to the sides? What causes that effect?
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?
Sense of smell, also known as olfaction, is the ability to perceive and interpret odours. When a chemical molecule interacts with an odour-receptor protein located on the sensory neuron in the nose, an action potential is triggered and sent along the axon.

- Applying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.arrow_forwardCertain cells in the retina respond differently to the direction in which objects move.

- Two branching dendritic arbors are stimulated at the same exact time at locations A & B which are both 10 um away from the axon hillock. Upon stimulation, location A depolarizes 20 mV and location B depolarizes 15 mV. The time constant is the same in both dendrites. The length constant in both dendrites is 10 um.
