Week 2 Review
Warm-up Exercises
Ventral Brainstem
From memory, draw and label:
- Ventral brainstem and it's parts
- Cranial nerves
- Sensory, motor or both?
- "Bumps" and sulci
Posterior Brainstem
From memory, draw and label:
- The medulla, pons and midbrain.
- Cranial nerves.
- Cerebellar peduncles.
- All the "bumps", bodies and
Spinal Cord Sections
Draw and label the following sections of the brainstem:
- Caudal Medulla
- Rostral Medulla
- Caudal Pons
