Neuron Structure
The part of the neuron that contains the nucleus.
What is the Soma/ Cell Body?
The three types of neurons are:
What are Sensory neurons, Motor neurons, and Interneurons OR Relay neurons?
This organ acts as the main control center of the nervous system by interpreting signals and directing the body’s actions.
What is the brain?
This is any change in the environment our sense organs pick up that causes a reaction in an organism.
What is a Stimulus or input?
In the structure of a neuron, the signals exits at this part.
What are the Terminal Endings OR Axon Terminal?
The parts of the Neuron are:
What are Dendrites, Soma/Cell Body, Nucleus, Axon, Myelin Sheath, and Terminal Endings?
These neurons send messages from your eyes, ears, and skin to your brain and spinal cord.
What are sensory neurons?
The Central Nervous System consists of these body parts:
What are the Brain and Spinal Cord?
This is how the body reacts after detecting a stimulus.
What is a response or output?
Neurons transmit messages in the form of:
What are electric impulses?
This part of the neuron collects the signal from either another neuron or from a sense organ and passes it to the Cell Body/Soma.
What are the Dendrites?
These neurons carry signals from the central nervous system to effectors like muscles.
What are Motor Neurons?
The Peripheral Nervous System is composed of:
What are Nerves?
Hearing a loud thunderclap makes you cover your ears. The loud thunderclap is this.
What is a stimulus?
A loud alarm sounds in the hallway. The signal first enters the nervous system through receptors located in this sense organ.
This part of the Neuron protects the signal as it travels down the axon.
BONUS: What other job does this part of the neuron have.
What are Myelin Sheath?
These neurons carry signals from sensory neurons to motor neurons during many reflex actions.
What are Relay Neurons?
These cells are the basic structural and functional units of the nervous system
What is a neuron?
Bright sunlight causes your pupils to get smaller. The pupil shrinking is this.
What is the response?
You touch a hot pan. The signal first enters the nervous system through receptors in your skin and travels along this type of neuron.
What are Sensory Neurons?
name the part of the neuron labeled as the long extension that carries impulses away from the cell body.
What is the Axon?
The space between two neurons is called _______.
What is Synapse?
The two main parts that make up the nervous system are:
What are the Central Nervous System and the Peripheral Nervous System?
Smelling smoke causes a person to leave a building. Leaving the building is this type of nervous system action.
What is a response?
The pathway of a message from the sense organs to the muscle is:
What is
Sense Organ -> Sensory Neuron -> Relay Neuron -> Motor Neuron -> Muscles?
