Nervous System Intro Flashcards
2 Branches of Nervous System
Central and Peripheral
2 Parts of Central Nervous System
Brain and Spinal Chord
2 Parts of Peripheral Nervous System
Cranial Nerves (12 pairs) and Spinal Nerves (31 pairs)
Nervous System Controls
Motor function, sensory function, memory and emotions
2 Functional Aspects of Nervous System
Automatic and Somatic
Automatic Nervous System Function
Regulates glands, blood vessels and internal organs
Somatic Nervous System Functions
Controls voluntary functions
2 Parts of Automatic Nervous system
Sympathetic (fight or flight) and Parasympathetic (rest and digest)
3 Types of Meninges Surrounding Brain and Spinal Chord
Pin Mater (in contact with nervous tissue), arachnoid mater, dura mater external envelope (towards bone)
Super Sagittal Sinus Function
Drains spinal fluid from brain and spinal chord into subclavian vein. Used in waste removal
Limbic System Function
Controls memories and emotion
Space between Pia and Arachnoid
Spinal fluid that acts as shock absorber, immune system and nutrient transfer system
Sulci Def.
Pits in brain
Gyri Def.
Flat bits in brain
Outermost meninge (closest to skull)
Dura
Innermost meninge (closest to brain/spinal chord)
Pia
Parts of brain stem
Midbrain, Pons and Medulla Oblongata
Pons Function
Axons conduit between brain and spinal chord
Medulla Oblongata Function
Conduit. Regulates breathing and heart rate control and autonomic functions
Midbrain Function
Autonomic System. Conveys information to the rest of the brain
Sagittal Section Def.
Vertical (left to right) section
Coronal
Vertical (top to bottom) sectional
Grey Matter Def.
Contains neuron cell bodies
White Matter Def.
Contains neuron axons and dendrites
Cerebellum Def.
Muscle control and balance
Caudate Nucleus Def.
Group of neurons in brain. Found in basal ganglia
