Flashcards in W19-L1: General Structure of the CNS Deck (6):
1

3 roles of thalamic nuclei

1. Relays sensory information to specific areas of cortex
2. Relays of non-sensory information from cortex and basal ganglia to specific areas of cortex
3. Project globally to cortex; arousal, sleep

2

Function of brainstem

Controls:
• Facial muscles
• Sensation from face and head
• Cardiorespiratory control
• Arousal, sleep/wake cycle

3

Dorsal roots axon type

sensory axons

4

Ventral root axon type

ventral horn motor axons (control skeletal muscle of body)

5

What is the structure of the Dorsal root ganglia neurons

Branching axon
• One branch in peripheral nerve – detects stimulus
• One branch enters dorsal horn via dorsal root

6

What does the BBB lack?

pinocytotic transfer, have very tight tight
junctions
