Brain & Nerve Z
Brain Parts and Nervous System - Bio I
| Question | Answer |
|---|---|
| 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. |
