Parts of the Brain
Controls most functions of the body and mind. It consists of two parts: the brain and spinal cord
CNS (Central Nervous System)
Test that detects changes in blood flow using magnets
fMRI
What part of the brain would be injured if you experienced a loss in motor functions?
Frontal Lobe
Contains the genetic information of the neuron
Nucleus
Carry signals from the outer parts of your body into the central nervous system
Sensory neurons
Relays information between your brain and the rest of your body. It consists of nerves and ganglia outside of the brain/spinal cord
PNS (Peripheral Nervous System)
Test that measures electrical activity in the brain using small, metal discs attached to the scalp
EEG
Which lobe of the brain plays essential roles in vision?
Occipital Lobe
Branches surrounding the cell body and they receive information
Dendrites
Carry signals from the CNS to the outer parts of your body such as your muscles, skin, and glands
Motor Nuerons
Located at the lower part of the brain and is connected to your spinal cord and is apart of your CNS
Brain Stem
Test that uses a radioactive dye that detects sugar use and blood flow in the brain
PET
Signals from the _________ regulates body temperature, thirst, hunger, and the circadian rhythm.
Hypothalamus
Combines information from different dendrites
Cell Body
In the 1930’s it was known as a “miracle cure” and was used to treat mental disorders
Lobotomy
Largest part of the brain split into two hemispheres
Cerebrum
Test that uses X-ray images taken from different angles to create cross-sectional images of the bones, blood vessels and soft tissues of the brain
CT Scan
What is the function of the myelin sheath?
It transmits the signal to other neurons
Which part of a nueron "moves the message along"?
Axon
What causes Multiple Sclerosis?
Demyelination
Located in the middle of the brain and is responsible for processing fearful and threatening stimuli
Amygdala
An abnormality seen on a brain imaging test that causes damage to the brain
Brain lesion
The ________controls the processing of your sense of smell.
Olfactory Bulb
Allows electrical impulses to transmit quickly and efficiently along the nerve cells
Myelin Sheath
Regulates growth, metabolism, and reproduction through the hormones that it produces
Pituitary Gland
