Brain & Nerve Z

Brain Parts and Nervous System - Bio I

QuestionAnswer
Cerebrum The largest major region of the brain involved in perception, thought, memory, voluntary movement, and other complex functions.
Cerebral cortex The outer layer of the cerebrum involved in complex processing, perception, cognition, and voluntary movement.
Frontal lobe Brain region involved in planning, decision-making, voluntary movement, language, and executive functions.
Parietal lobe Brain region involved in processing body sensations and integrating spatial information.
Temporal lobe Brain region involved in auditory processing, language, memory, and aspects of recognition.
Occipital lobe Brain region primarily involved in visual processing.
Cerebellum Brain region important for coordination, balance, motor learning, and fine-tuning movement.
Hypothalamus Brain region that helps regulate homeostasis, hormones, temperature, hunger, thirst, and other physiological states.
Hippocampus Brain structure strongly associated with memory formation and spatial learning.
Amygdala Brain structure involved in emotional processing, especially threat and fear-related responses.
Basal ganglia Group of structures involved in movement control, habit formation, action selection, and reward-related behaviors.
Prefrontal cortex Part of the frontal cortex involved in planning, judgment, decision-making, working memory, and impulse control.
Corpus callosum Large bundle of nerve fibers connecting the left and right cerebral hemispheres.
Thalamus A major relay and processing center for many sensory signals traveling to the cerebral cortex.
Brainstem Region connecting the brain and spinal cord and involved in vital functions such as breathing and heart regulation.
Motor cortex Cortical region involved in planning and controlling voluntary movement.
Sensory cortex Cortical regions that process information from sensory systems.
Visual cortex Cortical region primarily responsible for processing visual information.
Auditory cortex Cortical region that processes auditory information.
Limbic system A network of interconnected structures involved in emotion, motivation, learning, memory, and behavior.
Gray matter Brain and spinal-cord tissue rich in neuron cell bodies, dendrites, and synaptic connections.
White matter Tissue composed largely of myelinated axons that connect different regions of the nervous system.
Central nervous system (CNS) The brain and spinal cord.
Peripheral nervous system (PNS) Nerves and structures outside the brain and spinal cord that connect the CNS to the body.
Upper motor neuron A motor neuron located in the brain or spinal cord that communicates with lower motor neurons or motor circuits.
Lower motor neuron A motor neuron whose axon leaves the CNS and directly communicates with skeletal muscle.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
