Section 5: Brain and Heart
Brain Facts
1)
The central organ of the
human nervous system
2)
The brain consists
a)
Cerebrum
i. largest part of the human brain, divided into
two cerebral hemispheres
ii. Each hemisphere has four lobes; the frontal
lobe, (to control attention, abstract thinking, behaviour, problem solving
tasks, and physical reactions and personality), occipital lobe ( for visual
reception, visual-spatial processing, movement, and colour recognition),
parietal lobe, temporal ( to control auditory and visual memories, language,
and some hearing and speech)
iii. Outer part of the cerebrum is the cerebral
cortex made up of grey matter arranged in layers
iv. Beneath the cortex is the white matter of the
brain
v. The largest part of the cerebral cortex is the
neocortex (with six neuronal layers.)
vi. The rest of the cortex is of allocortex
vii. The two hemispheres are connected by commissural
nerve tracts with corpus callosum being the largest.
viii. the hemispheres are similar in shape and most
function except language is associated with left and visual-spatial ability in
the right.
b)
Brainstem. (divided into
the midbrain, the pons, and the medulla oblongata) Connects cerebrum to the
spinal cord.
c)
Cerebellum (important
role in motor control and perhaps do cognitive functions such as attention and
language)
3)
It controls most of the
activities of the body, processing, integrating, and it interrelates the
information received from the sense organs based on which it takes decisions for the rest of the body.
4)
Underneath the cerebral
cortex are the thalamus (large mass of gray matter with several functions such
as transmitting of sensory signals, including motor signals to the cerebral
cortex,) the epithalamus, the pineal gland, the hypothalamus, the pituitary
gland, and the subthalamus; the limbic structures
5)
The cells of the brain
include neurons (more than 86 billion neurons in the brain) and supportive
glial cells.
6)
Brain activity is made
possible by the interconnections of neurons who make form neural pathways,
neural circuits, and elaborate network systems and their release of
neurotransmitters in response to nerve impulses.
7)
Adult human brain weighs
4 pounds and comprises 60% of fat.
8)
It has the capacity to
generate 24 watts of power when awake.
9)
the brain gets 20%
of the total blood and oxygen that is produced in our body.
10)
neurons move information
at different speeds (fastest at 250 mph)
Heart Facts
1)
The heart is a muscular organ which pumps blood
through the blood vessels of the circulatory system
2)
Blood ( tissue) provides the body with oxygen and nutrients,
remove metabolic wastes
3)
It is divided into four chambers: upper left and
right atria; and lower left and right ventricles
4)
blood flows one way through the heart due to
four heart valves- one valve between each atrium and ventricle, and one valve the
exit of each ventricle
5)
Heart beats about 115,000 times each day and
pumps about 2,000 gallons of blood every day.
6)
The heart can continue beating even when it’s
disconnected from the body.
7)
A woman’s heart generally beats slightly faster
than a man’s heart.
8)
When the body is at rest, it takes 6 seconds for the blood to go from the heart to the lungs and back, time taken to travel back and forth the brain is 8 seconds and time taken to travel back and forth to toes is sixteen seconds
9)
The right heart collects deoxygenated blood from
the superior and inferior venae cavae. While in the left heart, oxygenated
blood is returned to the left atrium through the pulmonary veins.
10)
The pericardium is the sack that surrounds the
heart
