NERVOUS SYSTEMNervous system !!!
The nervous system begins pre-natally…
It eventually develops
into
the spinal chord with a
specialized extension,
the brainstem
The posterior portion of brain
stem develops the more specialized
cerebellum, and the anterior
Develops the cerebral hemispheres
THE CENTRAL NERVOUS SYTEM
Comprises two parts: the brain and
spinal chord
Encased in bone for protection. In
addition,
Cerebrospinal fluid circulates inside and
around
the brain for additional protection
Brain – the organ that directly controls
our thoughts,
emotions and motivations.
Spinal cord – a series of interconnected neurons
Extending from the brain to the center of the back.
It carries information to and from the brain
the two directional communication in the nervous
system involves two different kinds of nerves and
neurons…..
Receptors – are structures designed to receive sensory
information from the outlying
Nerves of the body and transmit that information back to the
brain thru the spinal chord
Effectors – transmit motor information about
how the body should act in response to the
Information it receives that usually comes from
the brain
The Peripheral Nervous System
Comprises all of the nerve cells except those of the brain and the
spinal cord.
The primary job of the PNS is to relay information between the
CNS and the receptors
And effectors lying outside the CNS.
The PNS connects with the receptors in both our external sensory
organs and our Internal body parts.
it connects with the effectors that
produce
Movement, speech and so on.
he PNS comprises of two main parts:
vous system – controls quick and conscious movement of
muscles. these muscles are attached directly to
the bone and allow us to move. We have voluntary
control over the muscles served by the somatic system
omic nervous system – controls movement of our non skeletal
muscles (heart and smooth muscles).
The smooth muscles
include those of the blood vessels and the
internal body organs
the Autonomic system is divided into two parts…..
Sympathetic nervous system - is concerned primarily with ‘catabolism,’
the process by which your body captures
stores, and uses energy and materials from
food and eliminate wastes
rasympathetic nervous system – concerned with ‘anabolism,’ the process that
stores energy in the body.
These two systems tend to work
in tandem….
T h e b r a i
n
Structures and functions
forebrain
Located toward the top and front of the brain
comprised of two parts: the telencephalon and diencephalon
Telencephalon:
- three parts
~ the cerebral cortex (outer layer of cerebral hemisphere)
plays vital role in our thinking
~ the basal ganglia
a collection of nerves crucial to motor functions
~ the limbic system
imp. to emotion, motivation and learning. Comprises
3 interconnected cerebral structures
a. hippocampus- plays an essential role in the
formation of memories
b. amygdala- plays a role in anger and
aggression
c. septum- involved in anger and fear
Diencephalon
- between the telencephalon and midbrain
- comprises the thalamus and hypothalamus
Thalamus- relays incoming sensory information thru
projection fiber to the appropriate
region in the cortex
Hypothalamus- involved in water balance in
tissues and bloodstreams. It
controls much of the autonomic
nervous system and endocrine system
also involved in temp. regulation.
interacts with and is sometimes
viewed as part of the limbic system
therefore involved in behavior
related to survival : fighting, feeding,
fleeing, mating.
hypothalamus
the main source of control for visual and auditory
Information. The reticular activating system of the midbra
Regulates state of consciousness, including sleep, wakefuln
Arousal, and attention, as well as breathing and heartbeat
Midbrain
hindbrain
Most rearward portion of the brain
1. Medulla oblongata- part of the reticular activating system
helps control heartbeat, breathing,
swallowing, digestion
2. pons- serve as a kind of relay station for signals
passing from one part of the brain to another.
3. cerebellum- involved in bodily coordination, balance,and
muscle tone.

Nervous system ppt (1)

  • 2. The nervous system begins pre-natally… It eventually develops into the spinal chord with a specialized extension, the brainstem The posterior portion of brain stem develops the more specialized cerebellum, and the anterior Develops the cerebral hemispheres
  • 3. THE CENTRAL NERVOUS SYTEM Comprises two parts: the brain and spinal chord Encased in bone for protection. In addition, Cerebrospinal fluid circulates inside and around the brain for additional protection Brain – the organ that directly controls our thoughts, emotions and motivations. Spinal cord – a series of interconnected neurons Extending from the brain to the center of the back. It carries information to and from the brain
  • 4. the two directional communication in the nervous system involves two different kinds of nerves and neurons….. Receptors – are structures designed to receive sensory information from the outlying Nerves of the body and transmit that information back to the brain thru the spinal chord Effectors – transmit motor information about how the body should act in response to the Information it receives that usually comes from the brain
  • 5. The Peripheral Nervous System Comprises all of the nerve cells except those of the brain and the spinal cord. The primary job of the PNS is to relay information between the CNS and the receptors And effectors lying outside the CNS. The PNS connects with the receptors in both our external sensory organs and our Internal body parts. it connects with the effectors that produce Movement, speech and so on.
  • 6. he PNS comprises of two main parts: vous system – controls quick and conscious movement of muscles. these muscles are attached directly to the bone and allow us to move. We have voluntary control over the muscles served by the somatic system omic nervous system – controls movement of our non skeletal muscles (heart and smooth muscles). The smooth muscles include those of the blood vessels and the internal body organs the Autonomic system is divided into two parts…..
  • 7. Sympathetic nervous system - is concerned primarily with ‘catabolism,’ the process by which your body captures stores, and uses energy and materials from food and eliminate wastes rasympathetic nervous system – concerned with ‘anabolism,’ the process that stores energy in the body. These two systems tend to work in tandem….
  • 8. T h e b r a i n Structures and functions
  • 9. forebrain Located toward the top and front of the brain comprised of two parts: the telencephalon and diencephalon
  • 10. Telencephalon: - three parts ~ the cerebral cortex (outer layer of cerebral hemisphere) plays vital role in our thinking ~ the basal ganglia a collection of nerves crucial to motor functions ~ the limbic system imp. to emotion, motivation and learning. Comprises 3 interconnected cerebral structures a. hippocampus- plays an essential role in the formation of memories b. amygdala- plays a role in anger and aggression c. septum- involved in anger and fear
  • 11. Diencephalon - between the telencephalon and midbrain - comprises the thalamus and hypothalamus Thalamus- relays incoming sensory information thru projection fiber to the appropriate region in the cortex Hypothalamus- involved in water balance in tissues and bloodstreams. It controls much of the autonomic nervous system and endocrine system also involved in temp. regulation. interacts with and is sometimes viewed as part of the limbic system therefore involved in behavior related to survival : fighting, feeding, fleeing, mating. hypothalamus
  • 12. the main source of control for visual and auditory Information. The reticular activating system of the midbra Regulates state of consciousness, including sleep, wakefuln Arousal, and attention, as well as breathing and heartbeat Midbrain
  • 13. hindbrain Most rearward portion of the brain 1. Medulla oblongata- part of the reticular activating system helps control heartbeat, breathing, swallowing, digestion 2. pons- serve as a kind of relay station for signals passing from one part of the brain to another. 3. cerebellum- involved in bodily coordination, balance,and muscle tone.
