Nervous System Michelle Carmona 5th period - Coggle Diagram

- - - - Neuron: Cells that communicate
        Neuroglia: Cells that support, nourish, protect, and insulate neurons.
- - - - Functions of the thalamus
        -Sorts and directs sensory information arriving from other parts of the nervous system to the cerebral cortex
        -Produces general awareness of the sensation,such as pain, touch and temperature.
      - Functions of the hypothalamus
        -Regulates heart rate and arterial blood pressure.
        -Controls movements and secretions of the digestive tract.
        -Regulates body temperature, water and electrolyte balance,
        hunger and body weight.
  - - - Functions of the cerebrum are
        -your Intelligence and personality
        -Interpretation of sensory input
        -Stores information for memory.
  - - - Midbrain
        -Located between the diencephalon and pons
        -Contains of the motor pathways between cerebrum and lower portions of the nervous system.
      - Pons
        Lies between the midbrain and medulla oblongata
        -Contains centers that help regulate the rate and depth of breathing.
      - Medulla Oblongata
        -Contains nuclei that control reflexes such as coughing, sneezing,
        swallowing, vomiting
        -Responisble for ascending and descending impulses between the brain and the spinal cord
        
        -Has three houses nuclei that control visceral functions which are cardiac center, vasomotor center and respiratory center
        
        Cardiac center: alters heart rate.
        
        Vasomotor center: controls vasoconstriction & vasodilation of blood vessels and helps control blood pressure
        
        .Respiratory center: Controls rate and depth of breathing.
- - - - Lumbar Enlargement
        A thickened region near the bottom of the spinal cord.
        -Provides nerves to the lower limbs
      - Cauda Equina
        Consists of spinal nerves in the lumbar & sacral areas
      - Cervical Enlargement
        A thickened area near top of spinal cord.
        -Provides nerves to upper limbs
- - - - Maxillary division: Sensory fibers conduct impulses from the upper teeth, upper gum, upper lip, lining of the palate, and skin of the face.
      - Mandibular division: Sensory fibers conduct impulses from the skin of the jaw, lower teeth, lower gum, and lower lip.
      - Ophthalmic division: Sensory fibers conduct impulses from the surface of the eyes, tear glands, scalp, forehead, and upper eyelids.
    - - Vestibular branch:Sensory fibers conduct impulses associated with the sense of equilibrium.
      - Cochlear branch: Sensory fibers conduct impulses associated with the sense of hearing.
    - - Sensory fibers conduct impulses from the pharynx, tonsils, posterior tongue, and carotid arteries.
    - - Somatic motor fibers conduct impulses to muscles associated with speech and swallowing;autonomic motor fibers conduct impulses to the heart, smooth muscle, and glands in the thorax and abdomen.
    - - Cranial branch: Motor fibers conduct impulses to muscles of the soft palate, pharynx, and larynx.
      - Spinal branch: Motor fibers conduct impulses to muscles of the neck and back.
- - - - 8 pairs of cervical nerves
      - 5 pairs of lumbar nerves
      - 12 pairs of thoracic nerves
      - 5 pairs of sacral nerves
      - 1 pair of coccygeal nerves
