B) Micro Glia
C) Oligodendrocyte

Principle stating that the size, amplitude, and velocity of the action potential are independent of the intensity of the stimulus that initiated it

Swelling of the soma, the point where the axon begins

 
network of thin tubes within a cell that transports newly synthesized proteins to other locations
A)  Endoplasmic reticulum
B) Golgi bodies
C) Mitochondria

The main fuel of vertebrate neurons

The main difference between Interneuron/Intrustic Neuron and Local Neuron?
A) Local Neurons are only located in the CNS
B) Size
C) Local neuron has none, or small axon

This drug that attaches to the sodium channels of the membrane, preventing sodium ions from entering and thereby blocking action potentials
A) Morphine
B) Cannabis
C) Cocaine
D) Local anesthetic

Myelin is mainly made of?

Nucleus has 2 meanings, which ones?

Tansmission of an action potential down an axon is termed?
A) Propagation of an action potential
B) Saltatory conduction
C) Graded potential
D) Mediated potential

This specialized type of Neuron is found in the CNS, specifically, the Brain, including cerebral cortex, the hippocampus, and in the amygdala.
One of the main structural features of this neuron is the special shape of the soma, or cell body, after which the neuron is named. Other key structural features of this cell are a single axon, a large apical dendrite, multiple basal dendrites, and the presence of dendritic spines.

Name these neurons

The blood-brain barrier requires certain chemicals to be Actively transported.
a) What is transporting the chemicals?
b) What is the fuel used to transport this?

Metabolism in the neuron is performed mainly by which structure

Myelin sheath gaps are also called...?

glia cells that surround and insulate certain axons in the vertebrate brain and spinal cord

type of glia cells that guides the migration of neurons and the growth of their axons and dendrites during embryological development
A) Radical Glia
B) Schwann cells
C) Radial Glia
D) Microglia

Term for the time when potassium gates remain open wider than usual, requiring a stronger than usual stimulus to initiate an action potential?

 
jumping of action potentials from one node to another by the flow of positive ions

N+ channels are only to be found where in a myelinated axon

glia cell that surrounds and insulates certain axons in the body of vertebrate are named
a) for PNS?
b) for CSN?

What chemical is necessary for the metabolism of glucose?
