Nervous System Classification Flashcards
What does the prosencephalon divide into
Telencephalon
Diencephalon
What does the Rhimbencephalon divide into
Metencephalon
Myelencephalon
What does encephalon mean
Brain
What does Myelos mean
Marrow/medulla
What region of the brain does the Prosencephalon refer to
Forebrain
What region of the brain does the Mesencephalon refer to
Midbrain
What region of the brain does the Rhombencephalon refer to
Hindbrain
What are the main functions of the forebrain
Receiving sensory info
What is the main function of the midbrain
Coordinate reflex responses
What are the functions of the hindbrain
Reflecting controls of respiration, blood circulation and dexterity
What make up the Central Nervous System
Brain
Spinal cord
What make the the Perhipheral Spinal Cord
Cranial nerves
Spinal Nerves
Ganglia (collection of cell bodies from nerves)
If nerves are only in the PNS what are the CNS equivalents
Tracts
What myelinates nerves
Schwann Cells
How does Myleination increase nerve impulse travel speed
Creates insulation, so impulses jumps between nodes of ranvier (less distance to travel along axon)
What nerves arrive the the CNS
Afferent
(Sensory)
What nerves leave the CNS
Efferent
(Motor)
What are special afferent nerves
Transport impulses for special senses
What is the difference between white and grey matter
White matter have myelinated axons
Which nerves have cell bodies
Sensory (afferent)
What makes up grey matter
Lots of efferent cell bodies
What is the Somatic nervous system
Voluntary - changes relative to the external environment
What is proprioception
How you sense your body ready to the space around you
What is the visceral nervous system
Involuntary - how your body maintains your internal environment
