21) Routine activities and energy conservation controlled by the:
A) peripheral : 1380929.
21) Routine activities and energy conservation are controlled by the:
A) peripheral nervous system.
B) parasympathetic division.
C) sympathetic division.
D) thalamus.
22) Which of the following would be a function of the sympathetic division?
A) stimulate the stomach
B) constrict the pupils
C) stimulate the gallbladder
D) accelerate heart rate
23) You are giving first aid to a semiconscious person who (before your arrival) told a bystander something about taking a drug overdose. The person has dilated pupils and a dry mouth. You recall reading that many drugs “mimic” the effects of nervous system functions, and you quickly size up which part of the nervous system is being mimicked here. The bystander is calling 911. In order to save time and best advise the emergency dispatcher about the treatment EMTs should be prepared to begin when they arrive, you tell the bystander to tell the 911 operator that the drug taken probably mimics which nervous system division?
A) somatic
B) parasympathetic
C) sympathetic
D) sfferent
24) Which of the following best describes the structural aspect of the cerebral cortex?
A) a thin band of gray matter making the outer layer of the cerebrum
B) a thick band of white matter making the outer layer of the cerebrum
C) a core of fast, myelinated axons in the interior of the brain
D) a cap of white matter over the spinal cord, made mostly of the thalamus
25) Most sensory information is routed through which structure before arriving in the cerebrum?
A) pons
B) medulla oblongata
C) midbrain
D) hypothalamus
E) thalamus
26) Which part of your brain processes the information in this question and, you hope, retrieves the information necessary to answer it?
A) cerebellum
B) cerebral cortex
C) pons
D) hypothalamus
E) midbrain
27) The term “brain dead” may refer to the fact that all brain centers have ceased to function except the:
A) cerebrum.
B) cerebellum.
C) thalamus.
D) hypothalamus.
E) medulla oblongata.
28) Proprioceptors provide us with:
A) sight.
B) hearing.
C) the sense of touch.
D) information about the position of the joints.
29) Which of the following best describes sensory receptors?
A) Sensory receptors interpret sensation.
B) Sensory receptors translate action potentials into stimuli.
C) Sensory receptors translate stimulation into action potentials.
D) Sensory receptors work through efferent pathways.
30) The Pacinian corpuscle is important to:
A) sight.
B) hearing.
C) the sense of touch.
D) information about the position of the joints.
