Brain (FINAL) Flashcards

Frontal Lobe
Part of Cerebrum
- Motor control (voluntary motor skills)
- Motor speech
- Concentration, planning, & problem solving
- “Thinking”

Parietal Lobe
Cerebrum
- Somato-sensory cortex = feeling/touch
- “Feeling” your body
- Understanding speech & using words

Occipital Lobe
Cerebrum
- Visual cortex = vision
- Process of “seeing” an image

Temporal Lobe
Cerebrum
- Hearing (pitches)
- Recognizing auditory patterns (“what am I hearing?”)
- Memories

Cerebellum
- Function: balance, coordination, & motor control
- “The bell of the ball loves to dance”
The brain stem is composed of what parts?
- Medulla oblongata
- Pons
What are the two parts of the medulla oblongata?
- Life support
- Decussation of pyramids
The life support function of the brain is found where?
Medulla oblongata in the brain stem
The decussation of pyramids is found where in the brain?
Medulla oblongata in the brain stem
The pons is found where on the brain?
The brain stem
The medulla oblongata is found __________ the pons
Below
What is the function of the life support function of the medulla oblongata?
Life Support
- Breathing
- Heart rate
- Heart beat
- Vomitting
- Coughing
What is the function of the decussation of pyramids of the medulla oblongata?
Decussation of Pyramids
- Cross over nerve tracts
- Right side of the brain crosses over to the left side of the body
- Left side of the brain crosses over to the right side of the body
What is the pons?
Pons = “bridge”
- The pons is a bridge from the lower brain (brain stem) to the upper brain (the higher brain)
What are the two functions of the pons?
- Bridge between the brain stem (lower brain) and upper brain (higher brain)
- Regulates breathing
- The pons tells the body how fast, slow, deep, shallow your breathing should be
- More complex breathng
What is another name for the midbrain?
Mesencephalon
What is another name for mesencephalan?
Midbrain
What are the components of the mesencephalan?
Mesencephalan
- Corpora quadrigemina
- Cerebral aqueduct
- Cerebral pedunc;e
What are the components of the midbrain?
Midbrain
- Corpora quadrigemina
- Cerebral aqueduct
- Cerebral peduncle
What is the function of the corpora quadrigemina
Corpora Quadrigemina
- Involuntary eye reflexes
- Dilating and constricting pupils
- Blinking
- Involuntary ear reflexes
- Ringing and muffles
- Turning ear to sound (turning and listening)
What is the function of the cerebral aqueduct?
Cerebral aqueduct
- The function of the cerebral aqueduct is to move/drain cerebrospinal fluid out of the brain
What is the function of the cerebral peduncles?
Cerebral Peduncles
- Peduncle = tracts (nerve bundles/ fibers)
- The cerebral peduncle connects the lower brain to the higher brain
- Carries information from the lower to higher parts of the brain
What is the function of the cerebellum?
Cerebellum
- Balance, coordination, and motor control
- “The bell of the ball wants to dance”
What part of the brain is considered the “second brain”
Diencephalon
