7. • The Central Nervous System (CNS)
The CNS has two major structures the brain
and the spinal cord.
• The brain is protected by the cranial
cavity and the spinal cord is
surrounded by the spinal cavity in
the vertebral column.
• They are both covered by protective
membranes called meninges.
• Question(s): What are the two
major structures of the CNS?
• What are these structures protected
by?
8. • The brainstem is the most inferior
portion of the brain. It is composed
The CNS of the following sections:
• Medulla Oblongata
• Pons
• Midbrain
• The lowest part of the brainstem is
the medulla oblongata.
• It is an enlarged extension of the
spinal cord. It lies inside the cranial
cavity above the foramen magnum.
• The medulla consists of gray and
white matter mixing to form the
reticular formation.
• Question: What are the three parts
of the brainstem?
9. • In the spinal cord, gray and white
matter do not mix. The core of the cord
The CNS is gray and the white matter surrounds
it.
• The pons and the midbrain consists of
white matter and scattered bits of gray
matter.
• All three parts of the brainstem function
as two way conduction paths.
• Sensory fibers conduct impulses up
from the cord to other parts of the
brain.
• Motor fibers conduct impulses down
from the brain to the cord.
• Question: What are the functions of
Sensory and motor fibers within the
CNS?
10. • Many important reflex centers are
The CNS located within the brainstem.
• Cardiac
• Respiratory
• Vasomotor
• Collectively these centers are called
vital centers and are located within
the brainstem.
• Impulse from these centers control
heart beat, respiration, and blood
vessel diameter – regulates blood
pressure.
• Question: What reflex centers make
up vital centers in the brain?
11. 1. What are the two major components of
the CNS?
2. What membrane is responsible for
The CNS Review 02/04 protecting both the brain and spinal cord?
3. What is the most inferior portion of the
brain called?
4. What are the three parts to the most
inferior portion of the brain?
5. Just above what cranial structure does the
medulla oblongata lie?
6. What does the reticular formation consist
of?
7. What function do all three parts of the
brainstem serve as?
8. What are the functions of sensory and
motor fibers within the CNS?
* You may select one of the above questions as
an exit ticket question.
12. • The cerebellum is the second largest part
of the human brain.
The CNS • It is located under the occipital lobe of the
cerebrum.
• The thin, folded outer layer forms a large
surface area and is composed of gray
matter.
• White matter forms most of the interior
portion of the cerebellum. The white
matter tracts form a tree-like pattern
called the arbor vitae.
• Functions of the cerebellum are:
• smooth, coordinated movements,
maintain equilibrium, and sustain normal
posture.
• It also may play a role in an overall
coordinating function of the entire brain.
• Question: What is the second largest part
of the brain?
13. • The diencephalon is a small, important
region of the brain. It is located
The CNS
between the midbrain and the
cerebrum.
• The diencephalon consists of three
major structures:
• Hypothalamus
• Thalamus
• Pineal gland
• The hypothalamus is located below the
thalamus.
• The pituitary gland and the walls of the
third ventricle are extensions of the
hypothalamus.
• Question: What are the three major
parts of the diencephalon?
14. • The hypothalamus is one of the most
important brain structures.
The CNS • The hypothalamus controls virtually all
internal organs.
• The hypothalamus controls:
• Heartbeat
• Constriction and dilation of blood vessels.
• Contraction of the stomach and intestines
• Body temperature
• Sleep cycles
• Appetite and emotions
• Some neurons of the hypothalamus
function to make hormones that the
posterior pituitary secretes into the blood.
One of these hormones is called ADH
(antidiuretic hormone) which affects the
volume of urine excreted.
• Question: What is the name of one of the
hormones released by the hypothalamus?
15. • Some of the neurons of the
The CNS hypothalamus function as glands.
• Their axons secrete chemical
releasing hormones into the blood.
• These hormones then cause other
hormones to be released by the
anterior pituitary gland.
• This action influences the hormone
secretion of other endocrine
glands.
• The hypothalamus indirectly helps
to control every cell in the body.
• Question: What are the functions of
chemical releasing hormones?

have?

in the absence of disease may be the result
of injury to what diencephalon structure?

question
17. • The thalamus is located just above
The CNS the hypothalamus.
• It is a dumbbell –shaped section of
gray matter.
• Each end of the dumbbell lies in a
lateral wall of a fluid filled chamber
called the third-ventricle.
• The thalamus is composed of
dendrites and cell bodies of
neurons that have axons extending
up toward sensory areas of the
cerebrum.
18. • The functions of the thalamus include:
The CNS • Producing sensations
• Associates sensations with emotions
• The pineal gland: Located posterior to
the thalamus protruding from the back
of the diencephalon.
• Receives information about the
strength of light seen by the eyes and
adjusts its output with the hormone
melatonin
• Melatonin helps to keep the body’s
clock on time with daily, monthly and
seasonal cycles of sunlight and
moonlight.
19. • The cerebrum is the largest portion
The CNS of the brain.
• It contains many convolutions (gyri)
and grooves called sulci.
• The deepest sulci are called fissures
• Fissures divide the cerebrum into
right and left hemispheres.
