ch. 12 Sensory Mechanisms chapter questions

Texting while driving involves which types of driving distractions?

• real and imagined

• spatial, temporal, and peripheral

• visual, cognitive, and manual

• oral, auditory, and perceptual

Some sensory receptors stop sending action potentials even though the original stimulus persists. This is known as

• receptor overload

• receptor adapation

• receptor shutdown

• receptor oversight

A stronger stimulus results in which one of the following?

• larger actions potentials

• greater frequency of action potentials

• action potentials that travel more quickly

• activation of more receptors and initiation of more action potentials

• neural fatigue

Which of the following receive(s) a physical or chemical stimulus and ultimately cause(s) nerve impulses to be generated in sensory neurons?

• the brain

• axons

• Schwann cells

• hillocks

• receptors

Which of the following receptors are MOST likely to demonstrate receptor adapation?

• pain receptors

• olfactory receptors in the nose

• photoreceptors in the eye

• stretch receptors in the muscles in tendons

• mechanoreceptors in the cochlea (ear)

Receptor adaptation occurs when

• impulse transmission stops at a synapse

• the brain ignores the incoming action potentials

• the stimulus stops

• the sensory neuron stops sending action potentials

• the action potentials from multiple sensory neurons cancel one another

Somatic receptors distributed throughout the body are linked to sensory neurons that send impulses to which one oof the following regions of the brain?

• pons

• medulla oblongata

• parietal lobe

• frontal lobe

• occipital lobe

A student noticed that when he closed his eyes, he could still determine the position of his arms and legs. This is largely due to the activity

• pain receptors

• mechanoreceptors

• Meissner's corpuscules

• chemoreceptors

Receptors for fast pain

• generally arise from muscles or internal organs

• give rise to a phenomenon called referred pain

• transmit action potentials to the brain along the same neurons used by the spinal neurons

• generally occur in or near the skin

• initiate action potentials that travel more quickly

An insufficent number of particular types of cones causes

• impaired night vision

• detachment of the retina

• impaired color vision

• glaucoma
