Chp 16 Sensory, Motor, and Integrative System

Which of the following is NOT a basic function of the sensory, motor, and integrative systems of the nervous system?

• Sleep in mammals

• Learning and memory

• Language

• Digestion

What is the term for the conscious or subconscious awareness of changes in the external or internal environment?

• Integration

• Sensation

• Perception

• Stimulation

What happens when sensory impulses reach the cerebral cortex?

• We become consciously aware of the stimulus and can identify specific sensations.

• The stimulus is ignored.

• The stimulus is amplified.

• The stimulus is converted into a motor response.

Which of the following is a general sense?

• Vision

• Hearing

• Somatic senses

• Equilibrium

Which sensory modality includes tactile sensations, thermal sensations, pain sensations, and proprioception?

• Visceral senses

• Somatic senses

• Special sensations

• Motor senses

Which of the following is a special sensation?

• Touch

• Pressure

• Smell

• Pain

What is the first step in the process of sensation?

• Integration of sensory input

• Generation of nerve impulses

• Stimulation of a sensory receptor

• Transduction of the stimulus

What must occur within the sensory receptor's receptive field for sensation to begin?

• A nerve impulse must be generated.

• An appropriate stimulus must occur.

• The stimulus must be ignored.

• The stimulus must be amplified.

What is the process called when a sensory receptor converts energy in a stimulus into a graded potential?

• Integration

• Transduction

• Generation

• Stimulation

What is required for the generation of nerve impulses in the process of sensation?

• The sum of graded potentials must reach threshold and trigger a nerve impulse.

• The stimulus must be ignored.

• The stimulus must be amplified.

• The receptor must be destroyed.
