Chapter 3 Flashcards
Neuron pathway
- Signal receives from a dendrite
- Passes through Axon
- End point: Axon terminal
Pyramidal cells
Makes up majority of the neurons in the Cerebral Cortex
These cells have heavy dendrite branching __________
Purkinje cells
Pathway of Motor Neurons
Spinal Cord - Muscles
Neurons around the nucleus and provides it with nutrients
Astrocytes
____________ maintains the blood brain barrier
Astrocytes
____________ is the waste removal of the brain and has an immune response to brain damage
Microglial cells
______________ produce cerebral spinal fluid
Ependymal Cells
Myelin forming cells in CNS
