What are the 7 main parts of the central nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).

What are the 5 parts of the central nervous system?

The CNS has three main components: the brain, the spinal cord, and the neurons (or nerve cells)….Spinal Cord

  • 8 cervical nerves.
  • 12 thoracic nerves.
  • 5 lumbar nerves.
  • 5 sacral nerves.
  • 1 coccygeal nerve.

What is the the central nervous system?

The central nervous system (CNS) is made up of the brain and spinal cord. It is one of 2 parts of the nervous system. The other part is the peripheral nervous system, which consists of nerves that connect the brain and spinal cord to the rest of the body. The central nervous system is the body’s processing centre.

What symptoms signal nervous system problems?

  • Loss of sight or double vision.
  • Memory loss.
  • Impaired mental ability.

What diseases affect the central nervous system?

Nervous system diseases

  • Alzheimer’s disease. Alzheimer’s disease affects brain function, memory and behaviour.
  • Bell’s palsy.
  • Cerebral palsy.
  • Epilepsy.
  • Motor neurone disease (MND)

What diseases affect the nervous system?

What are the 3 major organs of the nervous system?

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

How to strengthen your central nervous system?

Da rk chocolate – it is full of antioxidants,tryptophan and flavonols.

  • Bananas,oranges,and pomegranates – they are good sources of potassium.
  • Broccoli is rich in vitamin K,which is an essential component for brain health.
  • Eggs contain vitamins and minerals that are useful for the nervous system to function effectively.
  • What parts make up the peripheral and central nervous system?

    8 cervical nerves,which serve the chest,head,neck,shoulders,arms,and hands (called C1-C8).

  • 12 thoracic nerves,which serve the back,abdominal muscles,and intercostal muscles (called T1 – T12).
  • 5 lumbar nerves,which serve the lower abdomen,thighs,and legs (called L1-L5).
  • Which neurons are present inside the central nervous system?

    Afferent Neurons. Afferent neurons carry signals towards the CNS – afferent means “towards”.

  • Efferent Neurons.
  • Interneurons.
  • Astrocytes.
  • Oligodendrocytes.
  • Microglia.
  • Ependymal Cells.
  • Schwann Cells.
  • What Four Ways is the central nervous system protected?

    Soak a towel in water and rub your body with it,following the following pattern: hands and shoulders,feet,torso.

  • Alternating arm baths. Put your arms in hot water,one at a time. Then,put them in cold water.
  • Ending a bath with a cold shower is very beneficial.
