AP Psych: parts of the brain

pituitary gland
often referred to as the master of the endocrine system,
because it receives orders from a part of the brain located just above it and communicates those orders out to all of the other parts of the nervous system using “tropic” chemical messengers.

is the oblong-shaped part of the brainstem that controls a
person’s heartbeat, heart rate and breathing, among some of the most important survival functions.

the part of the brain that relays all sensory information
received from the body, except smell, to the appropriate part of the cerebral cortex for processing – for instance, it sends information from the eyes to the appropriate cortex where sight is processed.

is a part of the brain and component of the limbic system
that plays an essential role in the formation of new memories, as well as serving as one of the destinations for any sensory information related to the sense of smell.

Reticular activating system (RAS)
is the part of the brain located atop the brainstem, crossing
into the midbrain, whose function is to control alertness and arousal, that is greatly affected by alcohol consumption, and if severed, would result in you lapsing into a coma.

corpus callosum
is a wide band of neural fibers that connects the two hemispheres of the cerebral cortex together, allowing for communication and coordination of mental processes and behaviors between the left and right sides.

sympathetic nervous system
prepares the body fro emergencies, responsible for fight or flight response. brings blood from internals to externals (muscles), slows down digestion, signals adrenal glands to release hormones

cerebral cortex
layer covering the cerebrum

peripheral nervous system
carries info from the sense organs to the CNS and then from the CNS to the muscles and glands

frontal lobe; parietal lobe; occipital lobe; temporal lobe
front to back order of lobes

structure located above the medulla

parasympathetic nervous system
slows down conserves bodily resources. slows down heartrate, reduces blood pressure

Neurons that function within the brain and spinal cord

word recognition
is typically controlled by the left hemisphere

in the frontal, temporal, occipital, and parietal lobes
Association areas are located

Broca’s area
controls the muscles needed to form speech

somatic nervous system
nerves that connect voluntary skeletal muscles to sensory receptors (skin, muscles and joints)

central nervous system
the brain and the spinal cord.

right frontal lobe
During open brain surgery, Adam’s left ankle twitched whenever the surgeon electrically stimulated a specific area within Adam’s

plays a central role in emotional processes, fear, and agression

sensory neurons
brings info from sensory receptors to CNS such as from the eyes ears etc

Wernicke’s area
pieces together sights and sounds interprets auditory codes to establish meaning

The limbic system structure that regulates hunger

coordinating voluntary movement and enables nonverbal
learning and memory.

somatic nervous system and the autonomic nervous system
The two divisions of the peripheral nervous system are the
