The Brain
The part of the brainstem that controls heartbeat and breathing is the
medulla
The autonomic nervous system controls the internal functions, such as heart rate and glandular activity. The word autonomic means
automatic
This covers the axon and helps speed neural impulses
myelin sheath
a cerebral cortex area at the rear of the frontal lobes that controls voluntary movements
motor cortex
Failure to see visible objects because our attention is occupied elsewhere is called ____________ ___________.
inattentional blindness
The sensory control center
thalamus
The neurons of the spinal cord are part of the _________________ nervous system.
central
This part of a neuron receives messages from other cells
dendrites
a cerebral cortex area at the front of the parietal lobes that registers and processes body touch and movement sensation
somatosensory cortex
We register and react to stimuli outside of our awareness by means of ___________________ processing.
uncionscious/implicit
The three main parts of the brain that make up the limbic system
amygdala, hippocampus, hypothalamus
Our ______ nervous system enables voluntary control of our skeletal muscles
somatic
The tiny space between the axon of one neuron and the dendrite or cell body of another is called the
synaptic gap
the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
corpus callosum
When we devote deliberate attention to stimuli, we use _____________ processing.
conscious/explicit
The neural structure that most directly regulates homeostasis (eating, drinking, and body temperature) is the
hypothalamus
The __________ nervous system arouses and expends energy. Also, known as fight or flight system.
sympathetic
these neurons carry outgoing messages from the CNS to muscles and glands
motor neurons
If someone touched an area in the motor cortex on the left hemisphere of my brain, what would happen?
move an area of the right side of my body
Name two states of consciousness
sleeping, meditating, day dreaming, dissociation, mood altering substances, etc.
the “little brain” at the rear of the brainstem; functions include processing sensory input, coordinating movement output and balance, and enabling nonverbal learning and memory
cerebellum
The ___________ nervous system conserves energy as it calms you. Also known as rest and digest
parasympathetic
these neurons communicate within the central nervous system and process information between incoming and outgoing messages
interneurons
Name a body part that would take up a large amount of space in my somatosensory cortex.
Lips, fingertips, any areas that are more sensitive.
_______________ is our subjective awareness of ourselves and our environment
consciousness
