Sylvius Homework Assignment
Part 1 – Purves and sylvius brain atlas
Question 1; which 5 main brain subdivision arise from the neural tube vesciles
The 5 main brain subdivisions are: Telencephalon – diencephalon – mesencephalon
– metencephalon – myelencephalon
Question 2; in Purves Fig. A2, the central nervous system is divided on basis of
structures that can be recognized in all mammals. Which seven major structures are
used?
Telencephalon (cerebral cortex) – diencephalon – midbrain – cerebellum -- pons –
medulla – spinal cord
Question 3; which brain structure shows particularly strong developmental
characteristics in the human brain
Telencephalon is the most developed part in the human brain
Question 4; What component of the ventricular system do we encounter in:
Telencephalon – lateral ventricles
Diencephalon – third ventricle
Mesencephalon – cerebral aqueduct
Metencephalon – fourth ventricle
Myelencephalon – fourth ventricle
Question 5; What kind of neurological deficits would you expect to see if the 7 th
cranial nerve is damaged
The 7th nerve is the facial nerve it innervated the muscles of the facial expression and
have functions in the taste sensations.
When there is a deficit these functions are damaged.
Question 6; you are having a cavity filled and your dentist says that he caters to
cowards. Since you’re not in a heroic mood you accept the anaesthesia. (branches
of) which cranial nerve will the dentist try to target?
The dentist try to target cranial nerve V (trigeminal nerve), because these innervates
the muscles of the biting and chewing so this has to do with the teeth.
Question 7; What are gyri and suli?
Gyri: folded tissue
Suli; grooves that divide gryi
Question 8; what are hemispheres?
A hemisphere is one half of the cerebrum, the part of the brain that controls muscle
functions and also controls speech, thought, emotions, reading, writing and learning
Question 9; The cerebral cortex is characterized by a highly organized
cytoarchitecture that sets it apart from all other brain regions. Answer the following
questions using Purves.
1. Which features define cortical cytoarchitecture?
