#1
An organ of soft nervous tissue contained in the skull.
What is the brain
The largest part of the brain, divided into two hemispheres, or halves; it controls muscle functions, speech, thought, emotions, reading, writing, and learning
What is the cerebrum?
The portion of the brain in the back of the head between the cerebrum and the brain stem, which controls balance for walking and standing, and other complex motor functions.
What is the cerebellum?
The part of the brain that is connected to the spinal cord, which consists of the pons, midbrain, and medulla oblongata.
What is the brain stem?
Cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions.
What are motor neurons?
Part of the nervous system which, in vertabrates, consists of the brain and spinal cord
What is the Central Nervous System (CNS)
Located in the back of the cerebrum and is the visual processing area of the brain.
What is the occipital lobe?
Pair of cerebral lobes that are responsible for processing sensory information from the body, including touch, pain, temperature, and the sense of limb position.
What is the parietal lobe?
The nervous system containing the nerves outside the brain and spinal cord.
What is the Peripheral Nervous System (PNS)
A thing or event that evokes a specific functional reaction in an organ or tissue.
What is a stimulus?
The lobe of the cerebrum that is responsible for higher cognitive functions such as memory, emotions, impulse control, problem solving, social interaction, and motor function.
Pair of cerebral lobes that are involved in understanding language and learning and remembering verbal information.
What is the temporal lobe?
The uppermost portion of the brainstem, associated with reward, vision, hearing, and movement.
What is the midbrain?
Part of the brain stem that relays signals to the cerebellum and deals with respiration, bladder control, swallowing, along with other functions.
Pons
The lowest portion of the brainstem and the point where the spinal cord connects to the brainstem; maintains heart rate and respiration.
What is the medulla oblongata?
A nervous system cell specialized for electrical and chemical transmission of signals.
What is a neuron?
Finger-like part of the neuron that receives input from other neurons.
What is a dendrite?
The cell body of a neuron, which contains the nucleus and various other organelles.
What is soma?
Portion of a neuron that carries nerve impulses away from the cell body.
What is an axon?
Specialized area where a neuron contacts another cell; they allow for chemical communication between neurons and other cells through the use of neurotransmitters.
What is a synapse?
Part of the nervous system that extends from the brainstem to the lumbar vertebrae of the spine.
What is the spinal cord?
Cells that detect inputs from the environment, convert them into signals, and pass the information on to the brain and spinal cord, where a response can be generated.
What are sensory neurons?
