Nervous System Flashcards
What are the 2 types of neurotransmitters?
Excitatory and Inhibitory
What is an example of an excitatory neurotransmitter?
Acetylcholine, Norepinephrine, Dopamine
What is an example of an inhibitory neurotransmitter?
Acetylcholine, Gamma - aminobutyric acid (GABA), Glycine
What makes up the Central nervous system?
Brain, Spinal cord
What are the 4 main sections of the brain?
Cerebrum, Cerebellum, Diencephalon, Brain stem
The cerebrum is also known as?
Grey matter
Name the 4 lobes that make up the cerebrum.
Frontal lobe, Parietal lobe, Temporal lobe, Occipital lobe
The cerebrum is the largest part of the brain, responsible for higher brain functions.
What functions are associated with the frontal lobe?
Speech, Problem solving, Planning, Decision making, Emotional control
The frontal lobe is crucial for cognitive functions and control of voluntary movements.
What functions are associated with the parietal lobe?
Taste, Touch, Movement, Pain, Orientation
The parietal lobe is involved in processing sensory information from various modalities.
What functions are associated with the temporal lobe?
Hearing, Memory, Speech
The temporal lobe plays a key role in auditory processing and language comprehension.
What function is associated with the occipital lobe?
Vision
The occipital lobe is primarily responsible for visual processing.
Folds in the cerebrum are called?
Gyri
Gyri are the raised portions of the brain’s surface.
Deep grooves separating the gyri are called?
Fissures
Fissures are larger grooves that divide the brain into regions.
Shallow grooves separating the gyri are called?
Sulci
Sulci are smaller grooves that increase the surface area of the brain.
The cerebrum is separated into left and right?
Hemispheres
Each hemisphere of the cerebrum controls different functions and processes.
What is the 2nd largest part of the brain?
Cerebellum
The cerebellum is responsible for coordination and balance.
