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)
