Which functional area of the brain is responsible for our level of awareness and alertness?
Which functional area of the brain is responsible for our level of awareness and alertness?
The reticular activating system
is responsive to our sensory input and controls alertness to these sensory inputs and our awareness and responsiveness to our external (and internal) environment.
Which part of the brain is responsible for conscious control?
Its four major regions make this possible:
The cerebrum, with its cerebral cortex
, gives us conscious control of our actions. The diencephalon mediates sensations, manages emotions, and commands whole internal systems.
Which part of the brain is the executive suite that controls conscious brain activity?
Which part of the brain is the “executive suite” for all brain activity?
The cerebral cortex
is the “executive suite” of the nervous system, where our conscious mind is found. It enables us to be aware of ourselves and our sensations, to communicate, remember, understand, and initiate voluntary movements.
Which part of the cerebral cortex is involved in intellect cognition recall and personality?
| Question Answer | which part of the cerebral cortex is involved in intellect, cognition, recall and personality? prefrontal cortex | the primary auditory cortex is located in the ____ temporal lobe | which cells line the ventricles of the brain? ependymal cells |

What part of the brain keeps you awake and alert?
Your body’s internal clock is controlled by an area of the brain called the SCN (suprachiasmatic nucleus). The SCN is located in
the hypothalamus
. The SCN is sensitive to signals of dark and light.
Is the brain a solid organ that lacks cavities?
The brain is not a solid organ
. Instead, there are fluid-filled cavities within the brain called ventricles.
Which part of the brain controls conscious thoughts and voluntary movements?
The largest part of the brain,
the cerebrum
has two hemispheres (or halves). The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing.
Which of the following is considered the executive of the brain?
The cerebral cortex
is the “executive suite” of the nervous system, where most of our higher-level decision making occurs. It enables us to be aware of ourselves and our sensations, communicate, remember, understand, and initiate voluntary movements.
What are the major input and output pathways of the hypothalamus?
To exert its control over so many bodily functions, the hypothalamus uses three major outputs:
autonomic, endocrine, and behavioral systems
. In autonomic control, the hypothalamus contains neurons the send axons directly to the preganglionic neurons for both the sympathetic and parasympathetic nervous systems.
Which neural tracts convey information to the brain concerning temperature and pain?
Neural tracts that convey life-saving information to the brain concerning burning pain would be
the lateral spinothalamic tract
(option C). The lateral spinothalamic tract is responsible for the sensation of pain, temperature, light touch, pressure, tickle, itch, and sexual perceptions.
Which part of the cerebral cortex is mostly involved in intellect?
The frontal lobe is involved in reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement;
the prefrontal cortex
, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.
What would you find in the cerebral cortex?
The cerebral cortex is the largest site of neural integration in the central nervous system. It plays a key role in
attention, perception, awareness, thought, memory, language, and consciousness
.
What is the large commissure that connects the right and left sides of the brain?
The corpus callosum
is the largest set of commissural fibers in the brain and is a pathway of crucial importance to speech-language functions (Fig. 2-10, B). The corpus callosum serves as the major connection between the hemispheres and conveys neural information from one hemisphere to the other.
How long does it take for your brain to fully wake up?
Most people are fully alert
about 15 minutes after waking up
. Unless you’re sleep-deprived, in which case you’ll likely be foggy all day.
What hormone makes you wake up?
Melatonin
levels stay elevated for most of the night while you’re in the dark. Then, they drop in the early morning as the sun rises, causing you to wake up.
