What are Neurons?
Basic building block of the nervous system
Cells that carry information in the for of electrical pulses
What four parts make up the neurons?
What does the Dendrite do?
It picks up information.
What is the Cell Body for?
It organizes the information
What does the Axon do?
It carries the information
What does the Terminal Button do?
It passes the information on to organs, muscles, brain, skin, eyes, (everything)
What types of Neurons are there?
What do Sensory Neurons do?
They Transmit information about the inside world to the spinal cord and brain.
What do Motor Neurons do?
They convey messages from the brain and spine to muscles that control movement.
What do Interneurons do?
They connect Neuron to Neuron
Inside the spinal cord
They help us protect ourselves.
What order do that Neurons work?
What kind of beings are we?
How many stages does the electrical current take and what are they?
1) Resting potential
3) Action Potential
4) Refractory Period
What is Resting Potential?
When the cell is not sending out any information and is at rest
What is Depolarization?
When the Neuron is getting ready for the next step.
What is Action Potential?
When the cell is in action and is sending the message to the specific part of the body
What is Refractory Period?
Slowing down and stopping, as well as recovery period.
Define Nervous System
It's an intricate network of neurons that are organized in a complex communication network
What are the two points of the Nervous system?
Central and Periphiral
What does the Central Nervous system consist of?
What is the Hind Brain?
It controls the basic functions
What is the Mid Brain?
It's the section of the brain that allows us to take control of things.
What is the Forebrain?
It's your self of self
It's who you are
What is the job of the Spinal Cord?
To receive incoming info to be processed
Transmits outgoing info
Control's spinal reflexes
What is the three parts of the Hind Brain?
What is the oldest part of the brain?
The Hind Brain
What does the Mid Brain do?
It controls automatic movement of the eye muscles as well as the brain stem
It regulates attention, alertness, and arousal
(Alcohol interrupts this aspect of the brain-Drowsiness)
What is the largest part of the Brain?
What are the parts to the Forebrain?
What is the job of the Talamus?
It route information from the sense receptors
What is the job of the Hypothalamus?
Regulates Thirst, Hunger, Body Temperature, and Emotional States
(When the Hunger comes, the body stops regulating emotion and temperature to reserve energy)
What is the job of the Lymbic System?
What is the job of the Cerebral Cortex?
Responsible for our ability to:
What does the Cerebral Cortex Control?
States of Motivation
Processing of Sensory Information
How many hemispheres are there in the Cerebral Cortex?
How are the two Hemspheres of the Cerebral Cortex Connected?
By the Corpus Collosum
How Many Lobes does each Hemisphere have?
And What are they?
Where is the Occipital Lobe located?
The Back of the Brain
What does the Occipital Lobe do?
It Processes visual information
(Found in the back for protection)
Where is the Parietal Lobe located?
The sides of the Brain
What does the Parietal Lobe do?
It processes sensory information from the Body
(Hearing, touch, taste)
Where is the Frontal Lobe Located?
The front of the Brain
What Does the Frontal Lobe do?
It is the executive center of the brain
(Who you are)
Where is the Temporal Lobe located?
Beneath and Behind the Frontal Lobe
What does the Temporal Lobe do?
Performs higher mental Functions
(Reasoning, and stores memories *Works with the Frontal Lobe*)
What are the Brain Specializations for the LEFT side of the brain?
What are the Brain Specializations for the RIGHT side of the brain?
Non Verbal Processing
Processing Musical Sounds
What is the Brain Plasticity?
Flexibility in Processing
Adaptability for functioning (E.g. Stroke recovery)
Our mind is constantly figuring out how to communicate with newly formed neurons. It works on arranging where the safest place of the mind that the different parts can be. stops at a certain age
What age does Brain Plasticity stop?
