Nervous System

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
