15. Spinal Cord

16. Spinal Cord
A cordlike neural
structure encased in
the backbone that
serves as a pathway
for afferent &
efferent messages. It
is also the
connection center
for reflexes.

17. Reflex/es
Simple inborn automatic responses of some
parts of the body
Reflex Babinski Refl
Pu pillary ex
Moro / Startle Reflex

19. The Human Brain

20. The Human Brain
The part of the CNS that
lies within the skull. It is
the decision maker, the
central processor, and
the interpreter of
stimuli.
Controls our thoughts,
emotions and motivation.

THE BRAIN

25. PRINCIPAL SECTIONS OF
THE BRAIN
Hindbrain
Midbrain
Forebrain

26. The Hindbrain
THE SECTION OF THE
BRAIN CLOSEST TO
THE SPINAL CORD.
IT IS RESPONSIBLE
FOR THE BASIC LIFE
PROCESSES, LIKE
BREATHING, HEART
RATE, AND
TEMPERATURE.

IT IS LOCATED JUST ABOVE THE HINDBRAIN. IT

IS RESPONSIBLE IN CONNECTING THE
CEREBRUM WITH THE BRAINSTEM AND THE
N
SPINAL CORD.

28. Serves as the connecting link between hindbrain and
forebrain and have a special role in visual and auditory
activities.
Midbrain

29. THE LARGEST AND THE MOST COMPLEX PART OF THE HUMAN
BRAIN.
IT IS RESPONSIBLE FOR THE INTERPRETATION, DECISION
MAKING, AND OTHER HIGHER MENTAL FUNCTIONS.

Forebrain

31. Thalamus
THE MAJOR SWITCHING POINT
IN THE HUMAN BRAIN.

32. Limbic System
Hippocampus
Pituitary Gland
Amygdala

33. Cortex
CORTEX – The biggest
part of the forebrain. It is
divided into four (4)
lobes.
Frontal Lobe
Parietal Lobe
Temporal Lobe
Occipital Lobe

Nervous System

38. Voluntary Muscles
Activated when we’re
moving or in motion

Automatically activated
without a person conscious control

Conserves energy
Operates in relax state
