Divisions of the Central Nervous
System?
Brain and spinal cord.
Key word, central.

Coverings of the Brain and Spinal cord
The meninges
Dura mater
Arachnoid
Pia mater
Also called the Dural tube when referring just to the spinal cord
Cerebral spinal fluid flows in the subarachnoid space, provides buoyancy and protection to the CNS
Rectus Capitis posterior minor is said to have an attachment to the Dura mater

The Cerebrum -the largest portion of the
brain, the area of consciousness, intellect and
emotion, and skeletal motor movements
The Cerebellum-second largest part of brain,
controls co-ordination, balance, posture, muscle tone and complex movements

Brain Stem – Continuous with the spinal cord
midbrain (conducts impulses from the cerebrum to the pons
and sensory impulses from the spinal cord to the thalamus as
well as controls eye, head and neck movements in response to
visual and auditory stimulus),
pons varolli (relays impulses from one side of the cerebellum to
the other and helps control breathing)
medulla oblongata (conducts sensory and motor impulses
between the brain and spinal cord, and controls respiration,
cardiovascular impulses, digestive secretions, most vital
functions). The medulla oblongata is the most inferior part of
the brainstem
Diencephalon –
thalamus (sends sensory info to appropriate areas of the
cerebrum)
hypothalamus (regulates ANS and endocrine system by
controlling the pituitary gland, as well as circadian rhythm)
