central nervous system

2.  To know the general organization of human
nervous system.
 To understand about different parts of
nervous system.
 To get some inside about their funtions.

4.  The central nervous system is usually considered
to have seven basic parts:
1. Spinal cord
2. Medulla
3. Pons
4. Cerebellum
5. Midbrain
6. Diencephalon
7. Cerebral hemispheres

6.  For ease of memorizing central nervous
system is divided into three main parts:
 Forebrain
 Midbrain (Brainstem)
 Hindbrain

7.  Forebrain consists of:
 Cerebrum
 Thalamus
 Hypothalamus

10.  The cerebrum or cortex is the largest part of
the human brain, associated with higher brain
function such as thought and action.
 The cerebral cortex is divided into four
sections, called "lobes": the frontal lobe,
parietal lobe, occipital lobe, and temporal
lobe.

11.  Frontal Lobe- associated with reasoning,
planning, parts of speech, movement,
emotions, and problem solving
 Parietal Lobe- associated with movement,
orientation, recognition, perception of stimuli
 Occipital Lobe- associated with visual
processing
 Temporal Lobe- associated with perception
and recognition of auditory stimuli, memory,
and speech

13.  Thalamus and hypothalamus controls the
human emotions and termed as “The limbic
system” often referred to as the "emotional
brain"

14.  The midbrain consists of:
 Tectum
 Tegmentum

17.  It is involved in functions such as vision,
hearing, eye movement, and body movement.
 The anterior part has the cerebral peduncle,
which is a huge bundle of axons traveling
from the cerebral cortex through the brain
stem and these fibers (along with other
structures) are important for voluntary motor
function.

18.  Hindbrain consists of
 Cerebellum
 Pons
 Medulla

21.  Control of equilibrium is a vital function of
cerebellum.
 Cerebellum is specially vital during rapid
muscular activities like
 Running
 Typing
 Talking

22.  Pons- is the part of the metencephalon in the
hindbrain.
 It is involved in motor control and sensory
analysis for example, information from the
ear first enters the brain in the pons.
 It has parts that are important for the level of
consciousness and for sleep.
 Some structures within the pons are linked to
the cerebellum, thus are involved in
movement and posture.

23.  Medulla Oblongata- this structure is the
caudal-most part of the brain stem, between
the pons and spinal cord.
 It is responsible for maintaining vital body
functions, such as breathing and heart rate.
