The document summarizes the main parts and functions of the human nervous system. It is divided into three main parts: the forebrain, midbrain, and hindbrain. The forebrain includes the cerebrum, thalamus, and hypothalamus and is associated with higher functions like thought and action. The midbrain includes the tectum and tegmentum and is involved in vision, hearing, eye movement, and body movement. The hindbrain includes the cerebellum, pons, and medulla. It controls functions like equilibrium, motor control, sensory analysis, consciousness, sleep, breathing, and heart rate.

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
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"
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.
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.
