The Command Center (CNS & PNS)
This primary division of the nervous system consists only of the brain and the spinal cord
What is Central Nervous System
These branch-like structures act as the main "inputs" that receive signals from other cells
What are Dendrites
This part of the brain is essential for balance, posture, and muscle coordination
What is the Cerebellum
This large, upper part of the brain is responsible for high-level thinking and complex behavior
What is the cerebrum
Found at the very back of the brain, this lobe is dedicated to processing vision
What is the Occiptial Lobe
These two types of nerves—cranial and spinal—make up this "outer" nervous system
What is the Peripheral Nervous System
This is the long, cable-like part of the neuron that carries the electrical signal to its destination
What is the Axon
Located in the brainstem, this structure controls vital survival functions like breathing and heart rate
What is the Medulla Oblongata
This "relay station" directs incoming sensory information to the correct parts of the brain.
What is the Thalamus
Located near the temples, this lobe is responsible for hearing and language
Wha is the Temporal Lobe
This branch of the PNS controls voluntary movements, such as walking or waving
What is the Somatic Nervous System
This insulating layer speeds up signal transmission along the axon
What is the Myelin Sheath
This middle section of the brain helps coordinate basic visual and auditory reflexes
What is the midbrain
This small structure maintains the body’s internal balance, regulating things like temperature and hunger
What is the Hypothalamus
This lobe is the center for logic, personality, and voluntary movement.
What is the Frontal Lobe
This system manages involuntary functions like your heartbeat, breathing, and digestion
What is the Autonomic Nervous System
This specific area is the "threshold" or decision-point where a neuron fires an impulse
What is the Axon Hillock
These three structures—the medulla, pons, and midbrain—collectively form this "trunk" of the brain
What is the Brainstem
This group of structures is the brain’s "emotional center," involved in memory and feelin
What is the Limbic System
This specific part of the frontal lobe handles "executive functions" like planning and impulse control
What is the Prefrontal Cortex
These are the two specific divisions of the Autonomic system: one for "rest and digest" and one for "fight or flight."
What are the Parasympathetic and Sympathetic divisions
These are the small, uninsulated gaps between myelin segments where the signal is boosted
What are Nodes of Ranvier
This structure acts as a "bridge" between the cerebellum and the rest of the brain
What is the Pons
These are the two subdivisions of the forebrain: one containing the cerebrum and the other containing the thalamus
What are Telencephalon and Diencephalon
While the others focus on sight and sound, this lobe is responsible for processing touch and spatial awareness
What is the Parietal Lobe
