Neuro Flashcards
What are the two main parts of the nervous system?
Central Nervous System (CNS) and Peripheral Nervous System (PNS).
Which part of the nervous system controls everything?
Central Nervous System (CNS).
What are the two main pathways in the nervous system?
Motor (Efferent) Pathways and Sensory (Afferent) Pathways.
Which pathway sends signals from the brain to muscles?
Motor (Efferent) Pathways.
Which pathway brings sensory info to the brain?
Sensory (Afferent) Pathways.
What are the three major parts of the brain?
Forebrain, Midbrain, and Hindbrain.
Why does the brain need a lot of oxygen?
The brain requires 20% of your blood supply; low oxygen can lead to confusion or dizziness.
Which lobe controls vision?
Occipital Lobe.
Which lobe helps with hearing and memory?
Temporal Lobe.
What happens if Broca’s area is damaged?
A person can think of words but cannot say them (expressive aphasia).
What is the function of the frontal lobe?
Decision-making and movement.
Which lobe processes vision?
Occipital Lobe.
What happens if Wernicke’s area is damaged?
A person can hear words but not understand them (receptive aphasia).
What is the role of the Central Nervous System (CNS)?
Acts as the command center for the body.
What happens if the CNS is damaged?
Communication breaks down, affecting bodily functions.
What are the two types of motor control?
Pyramidal System and Extrapyramidal System.
What is the function of the Pyramidal System?
Controls voluntary movement.
What does damage to the Extrapyramidal System cause?
Movement disorders like Parkinson’s.
What does the Dorsal Column-Medial Lemniscus pathway do?
Carries fine touch, vibration, and proprioception information.
What does damage to the Spinothalamic Tract affect?
Ability to feel pain and temperature properly.
What is the function of the Prefrontal Cortex?
Controls decision-making, personality, and problem-solving.
What happens if the Primary Motor Cortex is damaged?
Weakness or paralysis on the opposite side of the body.
What is the role of the Occipital Lobe?
Processes vision.
What is Wernicke’s Area responsible for?
Helps understand language.
