Question

BIO150 BRAIN & CRANIAL NERVES ASSIGNMENT lecture tost. P4 in the texbok to complete this assignment. This material is on the next lecture test. Put the I. Introduction Just like the spinal cord, the brain has two protective structures answers in your own words and in the simplest terms as possible. 1) Bone: these are the skull bones 2) Meninges these are coverings made of CT The three meninges are dura, arachnoid and pia mater. They have the same structure, function, and location as the meninges of the spinal cord The meninges of the brain and spinal cord are continuouts Just like the spinal cord, the brain has gray and whi te matter. The structure and function If necessary of gray and white matter is the same between the brain and spinal cord. I review the structure and function of gray and white matter. Also review important definitions leamed from Unit 8 Part A lecture such as the terms nuclei, tracts, afferent efferent, sensory, motor, etc. The brain has four intenal chambers called ventricles (fig 14.6) which are found in the The interventricular The largest ventricles are the two-# region of the brain called the- #3 The foramen connects the lateral ventricle to the which is located cerebral aqueduct leads to the _#4- _._ _ and between the two regions of the brain called the-# the #7 CSF (cerebral spinal fluid) is continuously produced by the cells lining the subarachnoid space, by the ependymal cells lining the ventricles, and by a mass of blood capillaries The fourth ventricle forms the of the spinal cord which also contains CSF in the in the floor of each ventricle called the choroid plexus, CSF circulates between the ventricles of the brain, in the subarachnoid space, and in the central canal of the spinal cord (fig 14.7). Eventually the CSF is reabsorbed by the blood.
