Sensory Input
Receptors on or near body surface, respond to stimuli, and send messages to the Central Nervous System
Intergration
Central Nervous System receives, processes, and interprets the sensory information and decides what to do with it.
Motor Output
Central Nervous System sends information to muscles in response to sensory input.
sensory input, integration, and motor output
When you touch a hot stove (__________), a signal needs to go to your brain quickly so that you can realize it hurts(___________) and you ill your hand away (__________) before you do some serious damage.
Integration, motor output, sensory input
The three general functions of the Nervous System.
central nervous system and peripheral nervous system
The two main divisions in the nervous system
brain and spinal cord
Your central nervous system consists of these parts
Frontal lobe
Intelligence, motivation, behavior, memory, decision making, and emotions
Parietal lobe
Perception of touch, pressure, and pain
Occipital lobe
Visual perception (sight)
Cerebellum
Controls balance and coordination
Brainstem
Control breathing, heart rate, and other involuntary functions, sends signals to and from the brain
Temporal lobe
Understanding language and hearing
Vertebrae
Protects the spinal cord by encasing it
The spinal cord
Serves as an informational superhighway, passing messages from the body to the brain and from the brain to the body.
Brainstem, pelvis
The spinal cord is a thin, tubular bundle of nervous tissue that extends from the ___________ and continues down the center of the back to the __________.
The sensory division and the motor division
The two major parts that the peripheral nervous system
Peripheral nervous system
Consists of nervous tissue outside of the central nervous system
The sensory division
Carries messages from sense organs to the central nervous system.
the five senses
Sight, hearing, touch, taste, and smell
Sense organs
Eyes, ears, tongue, nose, and skin
sensory neurons
Receive message form the environment that cause a response in the body.
Occipital lobe
Sensory neurons in the eyes send messages to the brain about light. What lobe of the brain is this being sent to?
Parietal lobe
Sensory neurons in the skin send messages to the brain about touch. What lobe of the brain is this being sent to?
Motor division
Carries messages from the central nervous system to muscles and is further divided into the somatic and autonomic nervous system..
Central nervous system, muscles
The motor division carries messages from the _______________ to _______________.
Somatic nervous system
Controls voluntary commands to skeletal muscles, allowing a person to perform such actions as drinking, eating, and walking.
Autonomic nervous system
Carries autonomic (automatic) commands to a variety of muscles and glands throughout the body, allowing the brain to control this such as breathing, heart rate, blood pressure, and sweat production.
Dimension
An aspect of feature
Internal Ifluence
Choices from within you. (Likes and dislikes, morals and values)
External Influence
influences from around you. (friends, media)
Intrinsic Motivation
Performing an action or behavior because you enjoy the activity itself.
Extrinsic Motivation
When we are motivated to perform a behavior to claim a reward or avoid punishment.
Stimulus
Something that causes a specific reaction
Impulse
Electrical messages
Glands
An organ that produces and releases substances that perform a specific function in the body.
Sensation
The way we interpret senses
Integration
The process of combining information from different sources.
Vital
Absolutely necessary or important
Voluntary
To willingly do something
Neurotransmission
The process by which signals in the nervous system move from neuron to neuron.
Neurons
The building blocks of the nervous system. They generate signals which allow them to quickly transmit information
Dendrites
Receive information from other neurons
Axons
Send information to other neurons
Cell body
Is where the signals from dendrites are joined and passed on
Myelin Sheath
An insulating substance that speeds transmission
Synapse
Where information is carried from one neuron to the next
Sensory neurons and motor neurons
The two different types of neurons
Sensory neurons
Receive input from the environment
Motor neurons
Control motor (muscle) movement
