Nervous System Flashcards
What is the Nervous System?
A processing Information System consisting of the Central and Peripheral Nervous System
What is the function of the central nervous system?
The CNS consists of the Brain and Spinal Cord. Its function is to process sensor input and make decisions/give order
What are the 2 prominent neuroimaging tools?
- Computerized Tomography (CT)/Computerized Axial Tomography (CAT)
- MRI (Magnetic Resonance Imaging)

The Central Sulcus separates the ______ and ______ lobe.
The Central Sulcus separates the frontal and parietal lobe.
The Lateral Sulcus (Sylvian Fissure) separates the ____ lobe from the _____ lobe.
The Lateral Sulcus (Sylvian Fissure) separates the temporal lobe from the parietal and frontal lobe
What is the Longitudinal Fissure
Separates the left and right hemisphere
What is the function of the peripheral nervous system?
The PNS consists of the spinal and cranial nerves. That are somatic/autonomic
Somatic Nervous System
sensory and motor Nerves that are voluntary that innervates muscle and skin
Autonomic Nervous System
(Involuntary) Sensory & motor nerves innervate visceral
organs and glands.
Sympathetic/Parasympathetic
What does the Brainstem consist of ?
Midbrain
Pons
Medulla
What does the Cerebrum consists of?
Consists of two hemispheres, which each contain:
Cerebral cortex
Basal Ganglia
Diencephalon (Thalamus, hypothalamus…)
