Lecture: Anatomy of the Nervous System

Question 1

What are the names in the 3-vesicle stage?

Answer 1

Prosencephalon, Mesencephalon, Rhombencephalon

Question 2

What does the prosencephalon differentiate into?

Answer 2

Telencephalon and Diencephalon

Question 3

What does the mesencephalon differentiate into?

Answer 3

Mesencephalon –> Midbrain

Question 4

What does the rhombencephalon differentiate into?

Answer 4

Metencephalon and Myelencephalon

Question 5

What are the 3 layers of the meninges?

Answer 5

Dura mater, Arachnoid mater, and Pia mater (DAP mnemonic)

Question 6

What are the 2 major arteries that supply blood to the brain?

Answer 6

Internal carotid artery and vertebral artery

Question 7

Tracts

Answer 7

Axons within the CNS

Question 8

Unipolar (pseudounipolar) neuron

Answer 8

have a peripheral axonal process and a central axonal process that travel in a straight line, connected to the cell body only by a stalk that does not function in signal propagation

Question 9

Bipolar neuron

Answer 9

consist of one dendritic and one axonal process, with the cell body in-between. They are most often seen as the second neuron in sensory input layers (retina, olfactory bulb, etc.)

Question 10

Multipolar neuron

Answer 10

contains several arborized dendritic inputs and one arborized axonal output arising from the cell body
