Exam 4: The Peripheral Nervous System: Sensory, Autonomic, Somatic

How are high- and low-frequency sounds discriminated

What is the order in which a vibrational stimulus normally passes through the middle ear ossicles

What kind of receptor responds to acetylcholine released by all autonomic preganglionic fibres

Dual innervation of organs by both branches of the autonomic nervous system allows a fine degree of control over these organs.

Match the types of autonomic receptors, labelled a. through e., with their characteristic(s). (More than one answer may apply.) -response to activation of this type of adrenergic receptor usually excitatory

Which activity occurs in the presence of light within the phototransduction pathway

What are the various roles of secondary messenger systems in sensory pathways

Transmission of sound through the middle ear results in ______________________

Alpha and beta are two kinds of ____________________ receptors.

What are the three types of cones

Match the eye disorders, labelled a. through i., with their descriptions. (Options may be used more than once or not at all.) -lack of a cone type

What nerve fibres constitute the fast pain pathway

Which of these structures relay(s) incoming visual information to the appropriate cortical tissue

The semicircular canals are activated as the head starts to rotate, but cease responding if the head movement continues at the same rate in the same direction.

All postganglionic neurons bear __________________.

What are the various ways in which toxins can interfere with normal neuron function

The autonomic nervous system is part of the somatic nervous system.

Glucose interacts with ____________________ receptor binding sites on the surface of the tongue.

Match the eye disorders, labelled a. through i., with their descriptions. (Options may be used more than once or not at all.) -corrected by cylindrical lens

The salivary glands and the eye are sympathetically innervated by cranial nerves.
