Cards

Term
hindbrain
Definition
coordinates information coming into and out of the spinal cord
Term
medulla
Definition
an extension of the spinal cord into the skull that coordinates heart rate, circulation, and respiration
Term
reticular formation
Definition
a brain structure that regulates sleep, wakefulness, and levels of arousal
Term
cerebellum
Definition
a large structure of the hindbrain that controls fine motor skills
Term
pons
Definition
relays information from the cerebellum to the rest of the brain
Term
tectum
Definition
orients an organism to its environment
Term
tegmentum
Definition
involved in movement and arousal
Term
forebrain
Definition
highest level of the brain, controls complex cognitive, emotional, sensory, and motor functions
Term
cerebral cortex
Definition
the outermost layer of the brain visible to the naked eye, divided into two hemispheres
Term
subcortical structures
Definition
areas of the forebrain housed under the cerebral cortex near the very center of the brain
Term
thalamus
Definition
relays and filters information from senses and transmits the information to the cerebral cortex
Term
hypothalamus
Definition
regulates body temperature, hunger, thirst, and sexual behavior
Term
pituitary gland
Definition
the "master gland," releases hormones that direct the function of many other glands in the body
Term
limbic system
Definition
a group of structures that includes the hypothalamus, amygdala, and hippocampus, involved in motivation, emotion, learning, and memory
Term
hippocampus
Definition
creates new memories and integrates them into a network of knowledge so they can be stores in different parts of the cerebral cortex
Term
amygdala
Definition
plays a central role in emotional processes, particularly the formation of emotional memories
Term
basal ganglia
Definition
a group of subcortical structures that direct intentional movements
Term
corpus callosum
Definition
connects the two cerebral hemispheres
Term
occipital lobe
Definition
processes visual information
Term
parietal lobe
Definition
processes information about touch, contains the somatosensory cortex
Term
temporal lobe
Definition
controls language and hearing, contains primary auditory cortex
Term
frontal lobe
Definition
specialized areas for movement, abstract thinking, planning, memory, and judgement
Term
association areas
Definition
composed of neurons that help provide sense and meaning to information registered in the cortex
