Functions of The N.S.
Acts as the central communication system/control center.
What is nervous system?
Described as the "boss" of the nervous system, this organ controls thinking, feeling, moving, and processes information from our senses.
What is the Brain?
Structure act like wires that connect the brain and spinal cord to the rest of the body, carrying messages back and forth.
What is nerves?
Known as the main cells in the nervous system, these structures carry messages throughout the body.
What are neurons?
Known as "helper cells," these play a crucial role in supporting and safeguarding neurons.
What are glial cells?
Sight, Touch, Taste, Sound, and Smell
What is our 5 senses?
This structure is described as a "highway" that connects the brain to the rest of the body and transmits messages back and forth.
What is the Spinal Cord?
The division of the peripheral nervous system controls voluntary movements.
What is the somatic nervous system?
Responsible for receiving messages from other neurons.
What are dendrites?
Neurons send messages, which travel along the axon to reach the synapse.
What are electrical signals?
Brain sends signals to the muscles and glands to make the body respond.
What is motor output?
In addition to thinking and feeling, the brain controls this third primary action.
What is moving?
Controls involuntary bodily functions that happen automatically.
What is the autonomic nervous system?
Sends messages out to other neurons or body parts.
What is an Axon?
In addition to safeguarding neurons and maintaining their proper functioning, glial cells eliminate waste and supply these vital materials.
What are nutrients?
The nervous system gathers information from our senses and sends it to the brain.
What is Sensory Input?
This neural pathway is composed specifically of a single motor neuron and a single sensory neuron.
What is a Reflex Arc?
Part of the autonomic nervous system which arouses the body and expends energy during exercise or stress.
What is the sympathetic nervous system?
The tiny gap located between neurons where messages are passed.
What is synapse?
At the synapse, an electrical message is converted into this specific form of signal.
What is the chemical signal?
In this process, the brain takes in incoming sensory information and makes decisions about what to do.
What is integration?
The main function of the reflex arc is to send this specific type of movement towards the brain.
What is reflexive?
This system calms the body down and works to conserve energy.
What is the parasympathetic nervous system.
Specialized neurons that send informtation towards each neuron and intercept information between the two.
What is interneurons?
These chemical substances cross the synapse to pass the message along to the next neuron.
What are neurotransmitters?
