Science Flashcards
A network of cells called neurons coordinates actions and transmits signals between different body parts.
Nervous System
- central to the functioning of the nervous system
-They are able to communicate with other cells.
Neurons
The brain, spinal cord, and cerebellum
Central Nervous System
Sensory neurons, and neurons that communicate with other subdivisions.
Peripheral Nervous System
- One of the largest organs in the body.
- It centers all thought, memory, judgment, and emotion.
Brain
- Pain at the temples, in front of the ears.
- Commonly caused by: jaw injury, poor posture, misalignment of jaw
TMJ
- Pain behind the cheekbone
- Commonly caused by: colds
Sinus
- Pain in and around one eye
- Commonly caused by: insufficient sleep, stress, heat exhaustion, eye strain, alcohol & smoking.
Cluster
- Pain is like a band squeezing the head.
- Commonly caused by: fatigue, stress, depression, eye strain, caffeine, alcohol & smoking.
Tension
- Pain in the half of the face.
- Commonly caused by: fatigue, stress, depression, eye strain, caffeine, sleep pattern changes
Migraine
- Pain is at the top or back of head.
- Commonly caused by: poor posture, fatigue, over usage of gadgets, bad sleeping position, dehydration
Neck
These are layers of tissue that separate the skull and the brain.
Meninges
Outermost layer
Dura Mater
Thin and wispy
Arachnoid mater
Bound tightly to the surface
Pia Mater
- Known as the cerebral cortex
- The largest part of the human brain
- Associated with thought and action
Forebrain
Acts as the relay station for our visual and auditory systems
MidBrain
- Known as the brainstem
- One of the most important parts as it connects the brain to the spinal cord
- Associated with vital functions such as breathing and heartbeat.
Hindbrain
- The largest section of the brain
- Located in the upper portion of the brain which is responsible for thoughts, judgment, memory, problem-solving, and language.
Cerebrum
CEREBRAL HEMISPHERES
Right hemisphere
creativity and artistic ability.
CEREBRAL HEMISPHERES
Left hemisphere
analytical and mathematical ability.
LOBES OF THE CEREBRUM
Contains the language area of the brain.
– Left and right portions of the cerebrum.
Temporal Lobe
LOBES OF THE CEREBRUM
Receives and interprets nerve impulses.
– The most superior portion of the cerebrum.
Parietal Lobe
LOBES OF THE CEREBRUM
Controls vision and recognition.
— The most posterior portion of the cerebrum.
Occipital Lobe
