Week 1 Review

Question 1

Discuss the neuron doctrine
Golgi vs Cajal

Answer 1

Golgi: Reticular Theory: the nervous system has a continuous syncytial network

Cajal: Neuron Doctrine: neurons are not continuous and thereby communicate through contact

Question 2

Key components of a neuron

Answer 2

Soma
Axon - axon hillock - axon terminal
Dendrites

Nucleus - rER - golgi apparatus

Question 3

Neuronal structure and function, focusing on proteins involved in the neural cell body
(e.g., rough ER, mitochondria)

Question 4

Nissil vs Gogli stains

Answer 4

neuronal and glia cells

Question 5

Differentiate between neuronal cell types and glia cells

Answer 5

astrocytes, oligodendrocytes, microglia, and diseases

Question 6

Functions of mitochondria, smooth and rough ER in neurons

Answer 6

Mitochondria:

Question 7

Axoplasmic transport: anterograde vs retrograde transport, proteins, and ATP

Question 8

Classification of neurons: Based on structure (number of neurites, dendrites) and
function

Question 9

Glial cells and associated disorders: Be able to identify characteristics of astrocytes,
oligodendrocytes, microglia, and Schwann cells, along with diseases related to them
(e.g., MS, ALS)

Question 10

What is the role of the cytoskeleton in neurons and its involvement in neurodegenerative
diseases?

Question 11

The role of the BBB – blood brain barrier and the consequences of disruption

Question 12

What are the factors associated with the RMP- resting membrane potential?

Question 13

What is the role of the lipid bilayer?

Question 14

What is the difference between channels and pumps?
