Nervous System
This is the body's speedy electrochemical communication network.
What is the nervous system?
These are the chemical messengers that cross the gaps between neurons.
What are neurotransmitters?
This system uses glands to release chemical messengers into the bloodstream.
What is the endocrine system?
This brain structure helps control balance and voluntary movements
What is the cerebellum?
This lobe is located at the back of the brain and processes visual information.
What is the occipital lobe?
This division consists of the brain and spinal cord.
What is the central nervous system?
This part of the neuron receives messages and carries impulses toward the cell body.
What are dendrites?
These chemical messengers are released by endocrine glands and travel through the bloodstream.
What are hormones?
This almond-shaped structure is associated with fear, rage, and aggression.
What is the amygdala?
This lobe is located above the ears and processes auditory information.
What is the temporal lobe?
These neurons carry incoming information from sensory receptors to the brain and spinal cord.
What are sensory neurons? (afferent)
This fatty covering surrounds the axon and helps neural impulses travel faster.
What is the myelin sheath?
This division of the autonomic nervous system activates the body during stressful situations.
What is the sympathetic nervous system?
This brain structure regulates hunger, thirst, and body temperature.
What is the hypothalamus?
This lobe is responsible for planning, judgment, speaking, and voluntary movements
What is the frontal lobe?
These neurons communicate internally within the brain and spinal cord between sensory inputs and motor outputs.
What are interneurons?
This is the brief electrical charge that travels down the axon.
What is an action potential?
This division calms the body and conserves energy after a stressful situation.
What is the parasympathetic nervous system?
This structure in the limbic system is important for learning and memory.
What is the hippocampus?
This area of the left frontal lobe controls the muscle movements involved in speech.
What is Broca's area?
This division of the nervous system connects the central nervous system to the limbs and organs.
What is the peripheral nervous system?
This process occurs when neurotransmitters are reabsorbed by the sending neuron
What is reuptake?
These glands sit above the kidneys and release adrenaline and norepinephrine during stressful situations.
What are the adrenal glands?
This brainstem structure controls heartbeat and breathing.
What is the medulla?
Damage to this area of the left temporal lobe can make it difficult to understand spoken or written language.
What is Wernicke's area?
