A brain structure that helps regulate (via the Autonomic NS and the Endocrine System) many of the body's maintenance activities, such as eating, drinking, and body temperature.
The nerve cells that together from the nervous system -- allowing messages to travel to and from the brain.
Peripheral Nervous System
A network of sensory and motor neurons that connect the brain and spinal cord (CNS) with the rest of the body.
The gap that exists between neurons (specifically the gap between the axon terminals of the sending neuron and the dendrites of the receiving neuron).
A strip of brain tissue at the front of the parietal lobes that registers and processes body touch and movement sensations.
A brain structure that acts as the brain's sensory switchboard, directing messages from our senses (ex. eyes) to the sensory receiving areas in the brain's cortex.
The "little brain" attached to the rear of the brainstem -- it helps coordinate voluntary movements and balance.
Central Nervous System
The part of the nervous system that consists of the brain and spinal cord.
Somatic Nervous System
The division of the peripheral nervous system that controls voluntary movement of skeletal muscles.
A band of nerves that connects the two hemispheres of the cortex (left and right) and carries messages back and forth between them.
The thin outer part of the brain -- the brain's ultimate control and information processing center.
Autonomic Nervous System
The division of the peripheral nervous system that controls internal biological functions such as heart rate, breathing, blood pressure, and digestive processes.
A strip of brain tissue at the rear of the frontal lobes that controls voluntary movements.
The region of the cerebral cortex involved with decision making, problem solving, and planning, also includes the motor cortex.
The region of the cerebral cortex lying at the back of the head -- includes the initial (primary) visual processing areas of the brain.
The region of the cerebral cortex lying at the top of the head and toward the rear -- receives sensory input for touch and body position.
A brain structure involved in forming and indexing memories (part of the limbic system).
Part of the brainstem -- it controls basic life support functions like heartbeat and breathing.
Chemical messengers that cross the synaptic gaps between neurons, thereby influencing whether that neuron will or will not fire a neural impulse.
The division of the Autonomic NS that arouses the body to deal with perceived threats or strenuous activity.
Parasympathetic Nervous System
The division of the Autonomic NS that works to calm the body after an emergency or strenuous activity.
The region of the cerebral cortex lying roughly above the ears -- includes auditory (hearing) areas of the brain.
A nerve network in the brainstem that plays an important role in controlling wakefulness and arousal.
A brain structure that controls emotional responses, such as fear and anger (part of the limbic system).
