Study Guide – Nervous System, Nervous Tissue, and the CNS
1. A 75 year old patient develops a menigioma, a slow growing tumor
that arises from the middle meningeal layer. Which layer is the origin
of the menigeoma?
A= Arachnoid mater
2. Gyri are ridges on the surface of the brain that increase the brain’s
surface area. T or F
A= TRUE
3. Theta Waves are typically observed in who?
A= children and sometimes in adults during concentration
4. List functions of each
a- Medulla oblongata = regulates heart rate and respiratory rythmn
b- Midbrain = controls visual and auditory reflexes
c- Cerebellum= coordinates muscle movements and balance
d- Pons = conduction pathway between cerebrum and cerebellum
5. What structure separates the precentral gyrus and postcentral gyrus?
A= Central Sulcus
6. The fibrous cord that attaches the conus medullaris to the coccyx,
stabilizing the cord is what?
A = filum terminale
7. T or F- the corticospinal tract is responsible for carrying sensory signals
to skeletal muscles
A = False
8. Which structure in both human and sheep brain connect the brain and
the spinal cord?
A= medulla oblongata
9. Which spinal root contains the axons of sensory neurons?
A= dorsal root
10. A head injury has caused severe balance and coordination
problems in a patient. They struggle with walking, maintaining posture,
