The Nervous System The Brain

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?

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

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

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

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

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

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?

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

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