Presentation Transcript

  1. The Nervous System The Brain

  2. Cranial Meninges If the brain and spinal cord contain no pain receptors, what are the possible explanations for head pain? What is the function of the dural sinuses?

  3. Spinal Meninges Dura mater Epidural space Piamater Indicate the anterior (ventral) side in this view. Where are the dorsal root ganglia? Subarachnoid space Vertebral body

  4. Circulation of CSF Where is CSF made? Describe the chemical composition of CSF. How is CSF “recycled”?

  5. Forebrain: Cerebral Cortex List some of the functions of the cerebrum. Are the functions of both hemispheres identical?

  6. Functional Areas of theCerebral Cortex List and briefly describe the 4 types of functional areas.

  7. Forebrain – continued… Describe the structure and function of the reticular formation (RAS). Pineal gland Thalamus Hypothalamus Not shown: Neurohypophysis Optic nerves and tracts

  8. The Reticular Formation and RAS What information is received by the reticular formation? How is that information used? Where does awareness of sensation occur, and how is this different from sensation, and perception?

  9. Developments from the Midbrain Corpora quadrigemina Trochlear N. (IV) Cerebral peduncle Cerebral aqueduct Identify the pineal gland of the diencephalon. What features of the hindbrain are visible in this figure? What view is this?

  10. Developments of the Rhombencephalon (Hindbrain) Cerebellarpeduncles The reticular formation extends from the spinal cord to the diencephalon (thalamus). Name the brain structures in which this neuron “network” is found. Pons 4thventricle Cerebellum Medullaoblongata What kinds of information are sent to the cerebellum, and how is this related to its function? Name the important nuclei (control centers) in the pons and medulla.
