Quiz 4 CNS Part 1 APHY201

Which of the following best describes the multimodal association cortex? It integrates sensory input to produce understanding of an object being felt. It allows us to tie information that we receive to previous experience and knowledge and then helps us decide what action to take. It regulates our heart and other involuntary muscles in response to environmental stimuli. It permits the perception of sound stimuli and stores them for future reference.

It allows us to tie information that we receive to previous experience and knowledge and then helps us decide what action to take.

__________ is a division of labor in which each cerebral hemisphere has unique abilities NOT shared by its partner.

Lateralization

Which of the following best describes the nervous system function of integration?

The nervous system processes and interprets sensory input and decides what should be done at each moment.

__________ is responsible for communication between cerebral areas and between the cerebral cortex and lower CNS centers.

The thalamus

Obtaining medical histories and other information from a group of people with a particular disease and from a group without the disease to determine the relative frequency of a past exposure under study is an example of a:

case-control study

false

What part of the limbic system controls the increase of heart rate and respiratory rate, elevation of blood pressure, and diversion of blood to skeletal muscles?

hypothalamus

Which of the following is the autonomic control center?

hypothalamus

Which of the following is the autonomic control center? midbrain hypothalamus pons medulla oblongata

hypothalamus

Which part of the brain regulates thirst?

hypothalamus

Which of the following regions acts as an autonomic reflex center of the brain? medulla oblongata midbrain pons cerebellum

medulla oblongata

Nociceptors advise the brain of ___________.

pain

Localization and differentiation of thermal vs. mechanical (pressure) cutaneous stimuli involves the __________ cortex of the cerebrum.

parietal

Two point discrimination is processed in the __________ lobe.

parietal

The primary somatosensory cortex: perceives pain, temperature, touch, pressure, and conscious proprioception is located in the frontal lobe controls homeostasis is located in the occipital lobe

perceives pain, temperature, touch, pressure, and conscious proprioception

Which of the following is NOT a part of the diencephalon? epithalamus hypothalamus perithalamus thalamus

perithalamus

The ______________________ cortex resides in the postcentral gyrus of the parietal lobe, just posterior to the primary motor cortex. Neurons in this gyrus receive information from the general (somatic) sensory receptors in the skin and from proprioceptors (position sense receptors) in skeletal muscles, joints, and tendons. The neurons then identify the body region being stimulated, which is an ability called spatial discrimination.

primary somatosensory

All the following are functions of the amygdaloid body EXCEPT __________. assessment of danger or perceived threats emotional memory resolving mental conflict recognition of fear

resolving mental conflict

Blindfolded, a person is unable to identify the shape of a wooden cube placed in the left hand although the person can sense when the object was placed in the hand. The most probable location of the lesion is the:

right parietal association cortex

Which of the following is (are) dominated by the left cerebral hemisphere? intuitive thought artistic creativity solving math problems understanding jokes

solving math problems

Which of the following is most likely to be associated with a lesion (area of damage) of the frontal lobe? partial anesthesia flaccid paralysis partial deafness spastic paralysis

spastic paralysis

Concerning sensory perception, the two-point discrimination test assesses the patient's for __________.

spatial discrimination

Which of the following is a function of the basal nuclei?

thalamic nuclei

Before sensory information reaches the cerebral cortex, it is processed and integrated by the:

thalamus

thalamus and parietal cerebral cortex
