Parts of the Brain
Presented by: Raechel Davis
6 Main Regions






Cerebrum
Diencephalon
Midbrain
Pons
Medulla
Cerebrellum
Formation of the Brain Stem



Midbrain, Pons, and Medula are
components.
Responsible for relaying signals to the
Cerebrum and Cerebellum.
Involuntary & voluntary actions are
produced from these 3 regions.
The Medulla


Highway between the brain and spinal
cord.
Various nuclei transmit nerve impulses that
control:
- heart rate
- sneezing
- swallowing
- blood pressure
- constriction and dilation of blood vessels
Cerebrum



Lower posterior
portion.
Responds to signals
from: muscles,
tendons, joints.
Controls: skeletal
muscle contractions,
maintaining
coordination, muscle
tone, balance, and
posture.
2 Parts of the Diencephalon
Thalamus
Hearing
Taste
Vision
Sensation
Wakefulness
Voluntary Motor
Control



Hypothalamus
Autonomic nervous
system
Secretion from glands
Heart rate
Intestine movement
Rage,
Aggression
Water balance

Cerebral Cortex



Human consciousness, motor skills,
language, imagination are vital functions.
Within each hemisphere there are a
number of nuclei.
The Basal Ganglia and Limbic System
contain a number of different nuclei and
sub divisions.
Cerebral Cortex
Components of:
Basal Ganglia
Caudate nucleus
Putamen
Globus palidus
Sub thalamic nucleus





Limbic System
Hippocampus
Contributes to
emotional states such
as: fear, anger, rage,
pleasure, and sorrow.
Also assoc. with
learning and memory
capabilities.
